Dye coupling
Description
“One of the most elegant solutions to the problem of forming a colored image, lies in the utilization of the products formed by the action of the developer upon the latent image. By this means there is formed a dye image whose intensity follows closely that of the silver. This possibility was first realized by Dr. B. Homolka not long after the significance of the group relations in an organic developer was disclosed by the Lumieres, Seyewetz, and Andresen.”
