Colour Chemistry

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 or colour related phenomena are produced in response to a chemical or physical stimulus. This new edition will update the information on all those areas where chemicals or materials interact with light to produce colour, a colour change, or luminescence especially in the imaging, analysis, lighting and display areas. The book has been restructured to show greater emphasis on applications where 'coloured' compounds are used to transfer energy or manipulate light in some way therefore reducing the details on classical dyes and pigments. In the past eight years, since the previous edition, there has been a remarkable increase in the number of papers and reviews being produced reflecting the growth of interest in this area. This ongoing research interest is matched by a large number of new technological applications gaining commercial value covering e.g. biomedical areas, energy, data storage, physical colour, bio-inspired materials and photonics. This book appeals to industrial chemists, professionals, postgraduates and as high level recommended reading for colour technology courses.

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.

Volume 1 of the Handbook of Colorants Chemistry covers the fundamentals of color as well as the scientific principles, via the presentation of molecular compositions of inorganic and organic pigments. The book is supplemented by a comprehensive bibliography with references to standard works, monographs and original papers. The reader is provided with a unique overview of the field of color chemistry.

The updated third edition of the only textbook on colour The revised third edition of Colour and the Optical Properties of Materials focuses on the ways that colour is produced, both in the natural world and in a wide range of applications. The expert author offers an introduction to the science underlying colour and optics and explores many of the most recent applications. The text is divided into three main sections: behaviour of light in homogeneous media, which can largely be explained by classical wave optics; the way in which light interacts with atoms or molecules, which must be explained mainly in terms of photons; and the interaction of light with insulators, semiconductors and metals, in which the band structure notions are of primary concern. The updated third edition retains the proven concepts outlined in the previous editions and contains information on the significant developments in the field with many figures redrawn and new material added. The text contains new or extended sections on photonic crystals, holograms, flat lenses, super-resolution optical microscopy and modern display technologies. This important book: Offers and introduction to the science that underlies the everyday concept of colour Reviews the cross disciplinary subjects of physics, chemistry, biology and materials science, to link light, colour and perception Includes information on many modern applications, such as the numerous different colour displays now available, optical amplifiers lasers, super-resolution optical microscopy and lighting including LEDs and OLEDs Contains new sections on photonic crystals, holograms, flat lenses, super-resolution optical microscopy and display technologies Presents many worked examples, with problems and exercises at the end of each chapter Written for students in materials science, physics, chemistry and the biological sciences, the third edition of Colour and The Optical Properties of Materials covers the basic science of the topic and has been thoroughly updated to include recent advances in the field.

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.
