A Century of Progress In the Synthesis of Dyes for Photography

Abstract

Dyes had no place in the Daguerreotype and other photographic processes in vogue a century ago. Today, dyes are vital not only to colour photography but also in much black-and-white photography. They are used as colour sensitizers, as desensitizers, for the prevention of halation effects, as filter layers in colour photography, in colour filters, and they constitute the coloured images in colour photographic processes. The development of these applications of dyes is reviewed in this paper.
