Definitions for "Chromogenic"
A color print made from a color transparency in which the print material has at least three emulsion layers of silver salts sensitized to one of the three primary colors of light (blue, green, and red). During processing dye couplers are added that combine with the silvers to form the colors corresponding to each emulsion layer. The final image appears in full color when seen against the white base of the paper stock. (Baldwin, 24)
