This revised and up-dated second edition provides a current insight into how the fundamental principles of the chemistry of colour are applied in dyes and pigments. The text has been expanded and re-written throughout, while largely maintaining the structure of the first edition. In particular, the chapter on functional dyes has been substantially re-written to embrace the significant developments in chemistry and technology that this area has experienced in the last decade. As industry and society have become increasingly sensitive towards environmental issues, the chapter describing how the colour industry has been responding is expanded to reflect this growing importance. A new chapter is introduced on colour in cosmetics, with particular emphasis on hair dyes, reflecting the growing international, industrial significance of this topic. This chapter is co-written with Dr Olivier Morel. Colour Chemistry will be of interest to academics and industrialists who are specialists in colour science or who have involvement with the diverse range of coloured materials, for example traditional application in textiles, paints, printing inks, plastics and cosmetics, and functional applications in electronics and biology. Broad and balanced in its coverage, this book provides an introduction to the chemistry of colour that is ideal for students, graduates and those in industry and academia seeking an introduction to the topic.

This book provides an up-to-date insight into the chemistry behind the colour of the dyes and pigments that make our world so colourful. The impressive breadth of coverage starts with a dip into the history of colour science. Colour Chemistry then goes on to look at the structure and synthesis of the various dyes and pigments, along with their applications in the traditional areas of textiles, coatings and plastics, and also the ever-expanding range of "high-tech" applications. Also discussed are some of the environmental issues associated with the manufacture and use of colour. The broad and balanced coverage presented in this book makes it ideal for students and graduates. In addition, many specialists in industry or academia will also benefit from the overview of the subject that is provided.

Students embarking upon a colour chemistry course usually approach it by way of a general introduction and proceed to more detailed treatment of the subject when they have acquired some knowledge of its character and scope. This book has been written with the twofold purpose of serving as a guide to such students during the introductory part of their course and of supplying the needs in this field of others whose main interest is in a related branch of technology or pure chemistry. An attempt has been made to present the main features of the subject in an easily assimilable form. The great amount of published information renders the choice of material for a short book somewhat difficult, and I am keenly conscious of topics that might be thought worthy of more extensive treatment. However, a concise account cannot be comprehensive, and suggestions for further reading are provided at the end of the book. The chemistry of colouring matters can be regarded as a branch of pure chemistry, but the development of knowledge in this field has followed a course determined chiefly by the applications of dyes and pigments. It has therefore appeared appropriate to treat the subject here as a branch of technology.

Chromic phenomena, or those produced by materials which exhibit colour in response to a chemical or physical stimulus, have increasingly been at the heart of 'high-tec' developments in a variety of fields in the last decade. Many of the newer technologies, which are at the cutting edge of research, are multi-disciplinary, involving researchers from areas as diverse as physics, biology, materials science and electronic engineering. Chromic Phenomena covers five main areas: Colour change materials, such as photochromic, thermochromic and electrochromic materials; Materials which absorb and reflect light - the classical dyes and pigments; Luminescent phenomena, including phosphorescence, fluorescence and electroluminescence; Materials which absorb light and transfer energy, eg photosensitisers, infra-red absorbers and laser-addressable compounds; Phenomena involving the manipulation of light by chemicals, such as liquid crystals, lustre pigments, optoelectronics and photonics Providing an entry point both for new researchers and for established ones, this book, with its emphasis on the technological applications of these chromic phenomena, develops and investigates new applications for colour chemistry. It will be of interest to industrialists and professionals in the biological, medicinal, electronics/telecommunications and colorant industries, as well as academics in these fields.

The foundations of the chemical dyestuffs industry were laid in 1856 when W. H. Perkin discovered the dye Mauveine. At approximately the same time modern chemistry was establishing itself as a major science. Thus, the chemistry of dyes became that branch of organic chemistry in which the early scientific theories were first used. This early eminence has now been largely lost. In fact, many of our academic and teaching institutions pay little attention to this vitally important branch of organic chemistry. We believe that this book will help to rectify this unfortunate situation. The majority of books that have been published on the subject of dyes have been technologically biased and, in our opinion, do not appeal to the mainstream organic chemist. We have, therefore, aimed at producing a book which emphasises the role of organic chemistry in dyestuffs and we have included appropriate modern theories, especially the modern molecular orbital approaches. We have assumed that the reader possesses a knowledge of the basic principles of organic chemistry;* the only other requirement is a general interest in organic chemistry.** The book should interest the newcomer to chemistry, the established academic, and the dyestuffs chemist himself.

Just as colours are organized in the visual world according to the Pantone scale, so in the world of smell they are translated into a periodic table derived from chemistry. This exhibition catalog features a total of 88 works by Spanish and international artists, selected on the basis of olfactory criteria. Perfumers and flavourists communicate in a special language of their own, expressed in terms of "olfactory notes." Each of these notes is represented by a particular colour that helps the perfumer or flavourist to create it. This classification system, which combines smell, colour and art, provides the leitmotif of the present exhibition, which offers us a new appreciation of the links within the world of sensory perception and of how the chemical combinations that produce smells can awaken us to new realms of sensation.

In this brief, Mary Virginia Orna details the history of color from the chemical point of view. Beginning with the first recorded uses of color and ending in the development of our modern chemical industry, this rich, yet concise exposition shows us how color pervades every aspect of our lives. Our consciousness, our perceptions, our useful appliances and tools, our playthings, our entertainment, our health, and our diagnostic apparatus – all involve color and are based in no small part on chemistry.

Colour has fascinated man ever since he was able to see a coloured object. When Perkin manufactured the fast synthetic dye in 1857, little was known of the chemistry of dyes and about dependence of colour on structure. The principles concerning this relationship emerged over the next two decades. The principles are now fully described using the molecular orbital theory. This book deals with all aspects of the chemistry of colour.

Color is one of the most significant cues used by consumers to determine the quality of a food. While color is usually assumed to be a property of the food itself, it is actually the individual's response to the visual signals generated by light on the product. An authoritative reference can best explain the ways that food color and quality are assessed and how they can be improved to benefit consumers and the food industry. This book reviews how color is perceived and measured, discusses food color chemistry and stability, and presents ways that color can be better controlled in food. Part one introduces the concept of the total appearance of food and examines the principles of instrumental color measurement, models of color appearance, color measurement by color reflectance, and sorting by color. Part two covers color control in food, focusing on the chemistry of food colorants, color stability, genetic modification for color enhancement, and developments in natural colorings.
