Abstract
A survey of the history of monopack or multilayer photographic color processes, including the methods of greatest importance at the present time: (a) silver dye-bleaching methods and (b) silver dye-coupling methods. Silver dye-coupling methods appear to be most promising, and have been successfully applied to monopack films according to two distinct principles. In one method, color-forming compounds are added to the developing solutions. Color separation in this method depends upon control of the speed at which bleaching solutions penetrate superposed emulsion layers. In the second method, employed in the new Agfacolor process, the different color-forming substances, instead of being added to the developing solution, are incorporated in emulsions coated in superposition so that three differently colored images are simultaneously formed in a single development. The metallic silver is subsequently removed by solvents leaving only pure dye images. The process is based upon the pioneer work on color-forming methods of R. Fischer who, before the World War, developed the process substantially as it is now being used. The contributions to improving this process are the perfection of dyestuff-coupling components better than those available to Fischer, improved methods of preventing diffusion of the color-forming compounds, and methods of precisely controlling the manufacture of multilayer film upon a large scale.
