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.

At a time when more and more plants and animals are threatened with extinction by humanity's ever-increasing pressure on the land and oceans of the planet, this book sets out to record sources of colorants discovered and used on all the continents from antiquity until the present day. Some 300 plants and 30 animals (marine molluscs and scale insects) are illustrated and discussed by the author, whose passion for natural dyes, with their colors of unequalled richness and subtlety, has taken her across the globe in search of dye sources and dyers. Botanical and zoological details are given for each source and chemical structures for each dye. Dyes employed by different civilizations are illustrated and relevant historical recipes and detailed descriptions of dyeing-processes by traditional dyers are quoted and explained in the light of modern science. Other current uses of such colorants, such as in medicine, and as colorants for food and cosmetics, are also noted. Although natural dyes have been largely replaced by synthetic dyes, increasing worldwide awareness of the harmful consequences of the pollution resulting from the production and use of some synthetic colorants has led to a significant revival and renewed interest in natural colorants. As potential renewable resources, natural dyes are an integral part of the major issue of our time: sustainable development. The aim of this book is to provide a scientific background for this important debate."

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.

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.

In the last two decades the EPA and other national and international agencies have placed increasingly strict regulations on the manufacture and use of synthetic colorants. The pigment and dye industry has had to develop the technology necessary to analyze and remediate pollutants in wastewater. Although these efforts have produced a considerable volume of information, until now, no single book has provided an organized, comprehensive treatment of the environmental chemistry of synthetic colorants.

Environmental Chemistry of Dyes and Pigments is the first comprehensive reference to address the environmental problems posed by synthetic colorants, and to provide a forum for the solutions proposed by industry, government, and academia. Focusing on developments in the field over the past two decades, it deals with all aspects of colored wastewater treatment, the disposal of dyes, analytical methods, toxicity, and regulatory questions.

In its coverage of wastewater treatment, this book addresses both the most commonly used methods and those specifically designed to address pollution problems at the source by analyzing for and removing dyes and pollutants from wastewater effluent. Throughout, real-world data on a wide variety of dyes and dye intermediates is provided, as well as cost-effective strategies for dealing with wastewater treatment.

In addition, several chapters are devoted to the perspectives of national and international experts on regulations governing the manufacture, handling, use, and disposal of synthetic dyes and pigments. The impact these regulations have had on both U.S. and foreign industry is also discussed.

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.

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.

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.

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.
