Since Surface Coatings first appeared in 1974, the industry has undergone dramatic and rapid changes both in direction and emphasis, and this new edition mirrors these changes. Volume I includes coverage of aqueous systems, with chapters on emulsions and aqueous resins as well as providing an excellent introduction to polymer science, pigments, solvents and additives.
Although the research actIvItIes of dyestuff chemists worldwide have been influenced to a great extent, in recent years, by the need to respond to a variety of environmental issues associated with the manufacture and application of synthetic dyes and pigments, a significant level of targeted research continues to be devoted to new chemistry aimed at enhancing the technical properties of dyes in commerce. This book is a presentation of various aspects of basic research conducted during the past decade but not reported in the recent review literature. The coverage herein is unique in that it emphasizes systematic approaches commonly utilized in the design and synthesis of dyes and pigments and the required intermediates. While it is well known that certain transition metals are important in the synthesis of technically viable metallized dyes for polyamide and protein fibers, these metals are demonstrated in Chapter 1 also to be effective agents in the regiospecific placement of substituents into azo compounds. The scope and limitations of this chemistry are presented. In other synthetic work, a description of the different processes employed to produce the major families of reactive dyes is presented. In Chapter 4, special attention is given to reactive dyes containing more than one reactive group, and to the more recent developments in the field. The two chapters which follow provide a review of the recent literature pertaining to novel chromophores and dyes for the D2T2 process, respectively.
More than one and a half decades have passed since the last book was published describing developments in the analytical chemistry of synthetic colorants. In the intervening period, the scope and technical capabilities of instrumentation for analysing dyes and pigments has significantly expanded. It is now possible to rapidly resolve a number of problems whose solutions were previously either unattainable or very difficult to achieve. For instance, the unambiguous assignment of all the signals in the proton NMR spectrum of a trisazo direct dye, and the confirmation of the molecular weight of involatile, and, in particular, sulphonated dyes, without derivatisation, are now routine analytical techniques in many laboratories today. In addition, it is now possible to record the NMR spectrum of a dye molecule on less than 1 mg of material, and we are no longer limited to solution spectra, since solid samples can now be routinely analysed in NMR experiments. Whilst not attempting to be all encompassing, this volume is intended to bridge the gap between what was covered in the earlier work edited by Professor Venkataraman and the developments which have since ensued in some key areas. It provides important updates in X-ray crystallography, proton NMR, IR spectroscopy and mass spectrometry, and additionally covers topics such as ESR, micro spectrophotometry and emission spectroscopy.
This simple handbook aims to enable readers to make their own lake pigments or dye their own textiles using dyes from naturally occurring raw materials in a simple way under relatively controlled conditions and using recipes optimised for easy use in the laboratory or indeed the classroom. The book provides the basic principles of dying and lake pigment making (using the term lake pigment in its original, historical, sense indicating a naturally occurring dye precipitated onto a conventional usually white substrate, frequently a form of hydrated alumina) and from these the reader can try modifying the conditions or the amount of raw material, for example, to obtain different results. Suggestions for simple modifications are given. Contents: Introduction Natural dyes and their sources - plants, insect reds and shellfish purple The techniques of dyeing and pigment making - the basic chemistry behind the processes Recipes for dyeing Recipes for pigment making Bibliography
This treatise pertains to dyes composed of a central polymethine moiety and two cyclic terminal subunits. The polymethine linker can be unsubstituted or substituted, and at least one terminal subunit is a heterocyclic system. The classes of compounds reviewed range from classical cyanines, ?rst s- thesized in the 1850s, to hemicyanines, to styryl dyes, to merocyanines, to coumarinpolymethines, andtosquarylium dyesthatweresynthesized forthe ?rst time in the 1960s. These structurally diverse classes of compounds have one commondenominator, namely electronconjugation that involves the t- minalheterocyclic/aromaticsubunitsandthecentralpolymethinelinkerofthe molecule. Such conjugated molecules show absorption and ?uorescence that are a function of the structure of the three moieties. By changing the length and substitution of the polymethine linker and/or the structures of the t- minal moieties, molecules can be designed with absorption and ?uorescence ranging from the blue visible region (> 400nm) to the near-infrared region (> 700nm) of the electromagnetic spectrum. The synthetic developments of the last decade are reviewed and references to older but important work are provided tohelpdesignadye ofinterest fora desired speci?c application.

The role indigo has played elsewhere has been fairly well documented, but in the case of the Arab world, little or no thorough investigation has been previously undertaken. Sets out to provide comprehensive coverage of the subject from its earliest history to the present day.
Modern printing is based on digitizing information and then representing it on a substrate, such as paper, pixel by pixel. One of the most common methods of digital printing is through inkjet printers. The process of inkjet printing is very complicated, and the ink used must meet certain chemical and physicochemical requirements including those related to storage stability; jetting performance; color management; wetting; and adhesion on substrates. Obviously, these requirements - which represent different scientific disciplines such as colloid chemistry, chemical engineering, and physics - indicate the need for an interdisciplinary book that will cover all aspects of making and utilizing inkjet inks.This book provides basic and essential information on the important parameters which determine ink performance. It covers not only the conventional use of inkjet technology on graphic applications, but also the extension of this method to print various functional materials, such as the use of conductive inks to print light-emitting diodes (LEDs) and three-dimensional structures. Thus, the book will serve a large community: industrial chemists who deal with ink formulations and synthesis of chemicals for inks; chemical engineers and physicists who deal with the rheological and flow properties of inks; and researchers in academic institutes who seek to develop novel applications based on inkjet printing of new materials.

Drawing from the third edition of The Coatings Technology Handbook, this text provides a detailed analysis of the raw materials used in the coatings, adhesives, paints, and inks industries. Coatings Materials and Surface Coatings contains chapters covering the latest polymers, carbon resins, and high-temperature materials used for coatings, adhesives, and varnishes today. Featuring new and updated chapters, this text provides an in-depth examination of raw materials categorized into four types: resins, solvents, pigments, and additives. Concise chapters describe the development, chemical and physical properties, synthesis and polymerization, commercial uses, and other characteristics for each raw material and coating. In addition, the book demonstrates how application methods, environmental factors, and chemical interactions affect each surface coating's performance. Other unique topics include biocides, fluorocarbon resins, vegetable- and protein-based coatings and adhesives, gravure inks, and artists' paints. A comprehensive, yet practical source of reference, Coatings Materials and Surface Coatings provides an excellent foundation for comparing the properties and performance of coatings and choosing suitable materials based on specific service needs and environmental factors.
As our understanding of the science and functions of color in food has increased, the preferred colorants, forms of use, and legislation regulating their uses have also changed. Natural Colorants for Food and Nutraceutical Uses reflects the current tendency to use natural pigments. It details their science, technology, and applications as well as their nutraceutical properties.
Volume 3, like the preceding volumes, focuses on the diversity of surfactants, both in terms of chemical structure and physico-chemical / surface active properties. These properties may be predictable for simple molecules but, for most commercial surfactants (which may be regarded as multi-component blends), this is not so easy. Yet it is important to develop a greater understanding of the interactions within a multi-component mixture, in order to select the most appropriate product for a particular application in which a combination of surface active properties is required. A special feature of this volume is the initial chapter, in which the end uses of surface active agents are classified by industrial sector and the surfactant properties required for each application are presented in detail. The result is a unique guide to the influence of chemical structure on performance in end use, highlighting the benefits of particular surfactants and illustrating how some of the newer classes of surfactant may overcome the deficiencies of previously used products.
"Provides a wide range of information on the composition, utilization, and evaluation of colorants and pigments in food, pharmaceuticals, and cosmetic products. Tabulates key data for food, drug, and cosmetic colorants by Color Index Numbers. Thoroughly describes the relationships between coloring reactions."
This study sets out to provide coverage of the role of indigo in the Arab world, from its earliest history to the present day. It is based on fieldwork in all the principal countries concerned, as well as library and museum research, discussion with those working in related fields and personal experience of dyeing with indigo. The author surveys the story of indigo in antiquity, and then examines the record in the Arab world before Islam, during the Great Age of Islam, and in the subsequent centuries. She looks at all aspects in each period: technical, commercial, economic, and social, with reference to its importance in international trade and the impact of indigo products on Europe. The work covers each stage of indigo production, as well as the botanical and agricultural usages of indigo in the textile industry throughout the whole period, and the sundry purposes outside the field of textiles to which indigo has been put. The study ends with a brief look at indigo's future prospects.
Flavonoids are a group of natural products isolated from a wide variety of plants, responsible for much of the natural colouring in vascular plants. A single plant may contain up to 50 different flavonoids, and the distribution of flavonoids within a plant family can yield useful classifying information about that family. Flavonoids exhibit a wide range of biological activity and currently are of particular interest in the pharmaceutical industry as potential anti-cancer agents. They find applications in the food industry as natural food colourings and in the analysis of wine, and as insect anti-feedants, which are used as natural insecticides in agrochemistry and crop protection.
This book covers the chemistry of high solids compositions and focuses on the binder component and on the solvent. It discusses factors controlling the viscosity and the solid content of alkyd resins. The book describes different approaches to preparing high solid alkyds.
This book provides, for the first time, clear, authoritative guidance on removing graffiti and protecting surfaces from further attack.
Drawn from the third edition of The Coatings Technology Handbook, this book focuses entirely on testing, experimental design, and strategies for selecting processing techniques in the coatings, adhesives, paints, and inks industries. Coatings Technology: Fundamentals, Testing, and Processing Techniques contains the latest coating and processing methods capable of satisfying increasingly precise, application-specific requirements. The book contains analytical techniques used to elucidate surface chemistry, adhesion, and other physical properties. It also presents practical methods, such as accelerated light stability tests, to compare the resistance of different materials to wear, UV light/fading, and weathering. Subsequent chapters explore the most suitable techniques and the equipment for applying materials to different substrates, depending on material properties, service needs, and substrate types. Considering metal and nonmetal coatings and substrates, the book highlights the most recent advances on ink-jet printing, electrodeposition, vapor/chemical deposition technologies, high-speed dispersion, and other cutting-edge methods. Coatings Technology: Fundamentals, Testing, and Processing Techniques provides the the necessary information for scientists and engineers to perform testing and determine what materials and processing technique is most suitable for their own applications.
Increasing the Durability of Paint and Varnish Coatings in Building Products and Construction presents data and analysis on regularities in the appearance quality of protective and decorative coatings for building products and structures, also detailing the relationship between the resistance of coatings and the quality of their appearance. Developing a method for ensuring the quality of painted surfaces for building products and developing control methods is an important scientific, technical and economic problem. The conditions needed depend largely on the rheological properties of paint and the processes of wetting and application, with different variables for metal or concrete structures.
In the sixteenth century, one of the world's most precious commodities was cochineal, a legendary red dye treasured by the ancient Mexicans and sold in the great Aztec marketplaces, where it attracted the attention of the Spanish conquistadors. Shipped to Europe, the dye created a sensation, producing the brightest, strongest red the world had ever seen. Soon Spain's cochineal monopoly was worth a fortune. As the English, French, Dutch, and other Europeans joined the chase for cochineal -- a chase that lasted for more than three centuries -- a tale of pirates, explorers, alchemists, scientists, and spies unfolds. A Perfect Red evokes with style and verve this history of a grand obsession, of intrigue, empire, and adventure in pursuit of the most desirable color on earth.
In this book, industrial engineers and others will find a much needed introduction and reference on the science of coating. Drawn from a two-day course organized by the editors, this book delineates the major processes used in coating continuous webs, emphasizing precision application technology for the high performance coatings required by so many high-tech products. From fluid preparation and delivery through coating application and drying to finished product, expert contributors discuss limitations in speed and thickness, coating defects and their causes, handling the web, drying the coated web, and the effects on the process of the surface chemistry of coating fluid and coating support. The contributors represent the paper and converting industries as well as the photographic industry.
This book displays how optical (absorption, emission, and magnetic circular dichroism) spectra of phthalocyanines and related macrocyclic dyes can be varied from their prototypical ones depending on conditions. As these compounds can be involved in colorful chemistry (which might be driven by impurities in solvents), their spectra behave like the sea-god Proteus in their mutability. Therefore, those who have been engaged with phthalocyanines for the first time, including even educated professional researchers and engineers, may have been embarrassed by the deceptive behavior of their compounds and could have, in the worst cases, given up their projects. This book is aimed not merely at reviewing the optical spectra, but also at helping such people, particularly beginners, to figure them out by showing some examples of their prototypical spectra and their variations in several situations. For the purpose of better understanding, the book also provides an introduction to their theoretical backgrounds as graphically as possible and without mathematicization for readers who are weak in mathematics.
First published in 1919, as the second edition of a 1917 original, this book was written as part of the Cambridge Technical Series. The text provides a guide to the chemistry of dyestuffs and the dyeing process in two parts: part one discusses intermediate compounds; part two discusses dyestuffs. A bibliography and illustrative figures are also included. Notes are incorporated throughout. This book will be of value to anyone with an interest in applied chemistry, the history of science and the dyeing industry.
Arising from an examination in 1969 of the education and trammg opportumtles for paint industry technicians, it was recognized that the various courses available at that time did not fully serve their needs. While a few large companies had developed in-house training arrangements, the many medium and smaller fi.rms in the raw material supply, paint manufacturing or paint user industries, were unable to provide their own comprehensive training programs. With a view to improving this situation, an advisory committee comprising ofrepresentatives of the Australian Paint Manufacturers' Federation and the Oil and Colour Chemists' Association Australia was established to liaise directly with the New South Wales Department of Technical and Further Education. As a result plans were developed for the introduction of a Special Course in 'Surface Coatings Technology' in 1971, conducted by the Sydney Technical College. The scope of the course was designed to cover all aspects of surface coatings technology ranging from raw materials and formulations to the production, testing, evaluation, application and use of finished products. The course proved to be highly successful and in 1973 a similar syllabus was introduced by the Melboume School of Painting, Decorating and Signcrafts in Victoria. In 1980, New Zealand followed suit with a similar course conducted by the Auckland Technical Institute. |
