Book excerpt: The Chemistry of Synthetic Dyes, Volume VII covers the synthesis and application of dyes, fluorescent brightening agents, color and electronic states of organic molecules, photochemistry of dyes, and physical chemistry of dyeing. This book is organized into five chapters—sulfur dyes; Bunte salt dyes; state of dye in dyebath and substrate; kinetics, equilibrium, dye-fiber affinity, and mechanisms; and applications of synthetic dyes to biological problems. This compilation specifically discusses the sulfur dyes of known constitution, analysis of sulfur dyes, and chemistry of Bunte salts. The chemical modification of proteins and dyes as antibacterial and therapeutic agents is also treated. This volume is recommended for organic chemists and technologists interested in the synthesis of dyes and their applications.
