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.

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.

The science of pigments, hues, and dyes has a long and ancient history. From the 40000-years-old caves at Lascaux and the medieval cloth trade that enriched Europe to the synthetic chemistry of modern times, colour making has had a central place in our lives. This book surveys the history of dyes and pigments, the invention of new colours, and the industries that fuelled them. It explores colouring and dyeing methods through history and asks questions relating to this, such as: what were the colours of Ancient Egypt?; what did artists use to paint their magnificent frescoes?; where do indigo and ochre come from?; why is purple the colour of royalty?; what are pastels?; how many colours are their?; why do we dye our food?; who invented ink?; what are white and black made of?; and what is the symbolism of yellow? This comprehensive text offers information and insights into many colours ranging from cerise to heliotrope, and gamboge to periwinkle.

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.

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.

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.

Colour is a sensation and as such it is a subjective and incommunicable quantity. Colour measurement is possible because we can create a correspondence between colour sensations and the light radiations that stimulate them. This correspondence concerns the physics of light radiation, the physiology of the visual process and the psychology of vision. Historically, in parallel to standard colorimetry, systems for colour ordering have been developed that allow colour specifications in a very practical and concrete way, based on the direct vision of material colour samples arranged in colour atlases. Colour-ordering systems are sources of knowledge of colour vision, which integrate standard colorimetry. Standard Colorimetry: Definitions, Algorithms and Software: * Describes physiology and psychophysics useful to understand colorimetry * Considers all the photometric and colorimetric systems standardized by CIE (XYZ, CIELAB, CIELUV, LMS) * Presents colorimetric instrumentation in order to guide the reader toward colorimetric practice * Discusses colorimetric computation to understand the meaning of numerical colour specification * Considers colorimetry in colour syntheses and in imaging colour reproduction * Includes ready-to-use, freely-available software, Colorimetric eXercise , which has multiple toolboxes dedicated to * displaying CIE systems, atlases, any colour and its whole numerical specification * colour-vision phenomena and tests Standard Colorimetry: Definitions, Algorithms and Software is an accessible and valuable resource for students, lecturers, researchers and laboratory technicians in colour science and image technology.
