The science of chemistry is so broad that it is normally broken into fields or branches of specialization. The manufacture of drugs and dyes is one of the most practical industrial applications of chemistry. This collection presents the reader with a broad spectrum of chapters on drugs and dyes, thereby demonstrating key developments in this rapidly changing field. It examines dyes in chemical interaction and production of drugs for pharmaceutical use as well as in forensic work and in the production of materials.

The first edition of the Printing Ink Manual was published by the Society of British Printing Ink Manufacturers in 1961 to fill the need for an authorative textbook on printing technology, which would serve both as a training manual and a reliable reference book for everyday use. The book soon became established as a standard source of information on printing inks and reached its fourth edition by 1988. This, the fifth edition, is being published only five years later, so rapid has been the development in technology. The objective of the Printing Ink Manual remains unchanged. It is a practical handbook designed for use by everyone engaged in the printing ink industry and the associated industries. It provides all the information required by the ink technical for the day-to-day formulation of printing inks. It supplies the factory manager with details of the latest equipment and manufacturing methods, including large-scale production, and gives guidance on achieving quality assessment and total quality management specifications. Care has been taken to maintain the value of the Manual for training both technical personnel and others who requiresome kn- ledge of inks. Readers with little scientific knowledge will not find dif- culty in using the Manual, but sufficient chemistry and physics have been included to provide an explanation of the underlying principles and theories governing the behaviour of inks for use by the advanced te- nologist. Suppliers of raw materials, substrate manufacturers, printers and print users will find the book a valuable source of information.
