Copycolor

“Agfa-Gevaert developed its own instant printing materials during the 1980s, Agfachrome-Speed and Copycolor, both introduced commercially in 1983. Agfachrome-Speed was a single-sheet integral print material, whereas Copycolor was a peel-apart. Like their direct competitor, Ektaflex PCT, they gave photographers an easy way to obtain enlargements from color transparencies, without complicated manipulation or equipment. The image-forming chemistry of the films was based on a dye release mechanism in which dye releasers in unexposed regions of the negative were reduced to release a diffusible image dye (Walworth and Mervis 1997: 335).

Copycolor’s chemistry was similar to that of Agfachrome-Speed. Following exposure, the negative was fed together with either a print or a transparency positive sheet into a Copyproof-processor containing the alkaline activator. The two sheets were brought into close contact by laminating rollers. When processing was complete, the sheets were peeled apart, the negative was discarded, and the positive print or transparency was rinsed and dried (Walworth and Mervis 1989: 224).”
