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, the chapter describing how the colour industry has been responding to environmental issues is expanded to reflect this growing importance and a new chapter is introduced on colour in cosmetics. Broad and balanced in its coverage, this book is ideal for students, graduates and those in industry and academia seeking an introduction to the topic.
