In this book the authors go back to basics to describe the structural differences between dyes and pigments, their mechanisms of action, properties and applications. They set the scene by explaining the reasons behind these differences and show how dyes are predominately organic compounds that dissolve or react with substrates, whereas pigments are (predominantly) finely ground inorganic substances that are insoluble and therefore have a different mode of coloring. They also describe the role of functional groups and their effect on dyeing ability, contrasting this with the way in which pigments cause surface reflection (or light absorption) depending on their chemical and crystalline structure and relative particle size. The book explores the environmental impact of dyes in a section that covers the physical, chemical, toxicological, and ecological properties of dyes and how these are used to assess their effect on the environment and to estimate whether a given product presents a potential hazard. Lastly, it assesses how, in addition to their traditional uses in the textile, leather, paper, paint and varnish industries, dyes and pigments are indispensable in other fields such as microelectronics, medical diagnostics, and in information recording techniques.

Chronicles the history of dyes and pigments and their related industries, discussing colors in the Middle Ages; the explosion of supply and demand in the sixteenth, seventeenth, and eighteenth centuries; and advances in industrial chemistry.

The purpose of this essay collection is to recover color's complex and sometimes morally troubling past. By emphasising color's materiality, and how it was produced, exchanged and used, contributors draw attention to the disjuncture between the beauty of color and the blood, sweat, and tears that went into its production, circulation and application as well as to the complicated and varied social meanings attached to color within specific historical and social contexts.

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.

Colour is all around us; we take it for granted as a naturally occurring element of all things. Yet colours are also manufactured, and the science of pigments, hues and dyes has an ancient and fascinating history. This book surveys the story of dyes and pigments, the invention of new colours and the industries that were fuelled by them. What were the colours of ancient Egypt? What did its 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 there? Why do we dye our food? Who invented ink? What is the symbolism of yellow? From cerise to crimson, from puce to periwinkle, this book is as rich, varied and delightful as a box of crayons.
