Preface to Volume 1
This Second Edition of a textbook first published in 1990 forms part of a series on colour and coloration technology initiated by the Textbooks Committee of the Society of Dyers and Colourists under the aegis of the Dyers’ Company Publications Trust Management Committee, which administers the trust fund generously provided by the Worshipful Company of Dyers.

The initial objective of this series of books has been to establish a coherent body of explanatory information on the principles and application technology of relevance for students preparing to take the Associateship examinations of the Society. This particular book has been directed specifically to the subject areas covered by Section A of Paper B: the organic chemistry and application of dyes and pigments and of the auxiliaries used with them in textile coloration processes. However, many qualified chemists and colourists interested in the properties of colorants and their auxiliaries have found the First Edition useful as a work of reference. For several reasons it has been convenient to divide the material into two separate volumes: 1. Colorants, 2. Auxiliaries. Although fluorescent brighteners share some features in common with colorants, they have been treated as auxiliary products in this book.

This first volume of the book is concentrated on the chemical characteristics of dyes and pigments, with emphasis on attempts to interpret their colouring and fastness properties in terms of the essential structural features of colorant molecules. This Second Edition has been extensively updated and greater attention has also been given to factors associated with the potential impact of colorants and their metabolites on the environment. All chapters have been affected by these changes, but the concluding chapter on reactive dyes contains more new material than the others. Rationalisation of the global dyemaking industry during the 1990s means that many of the traditional commercial names of dyes and pigments have disappeared. For this reason Part 2 of the Colorants Index has been eliminated and colorants have been specified almost always by their CI Generic Names. The fundamental value of the unique Colour Index International to colorant makers and users is recognised worldwide.

Chapters 4 and 7 in the First Edition were written by Vivian Stead and Chapter 5 by Frank Jones. Sadly, Frank died in 1989 and Vivian in 1996, but my co-authors and myself would like to record our tribute for the major contributions to this volume by our former friends and colleagues. We have tried to preserve their original style intact during the necessary updating process. Our grateful thanks are due to John Holmes and Catherine Whitehouse for their patient copy editing and to the publications staff of the Society, especially Carol Davies, who have prepared all the material in this new edition for publication.
