发明名称 PHOTOGRAPHIC MATERIAL AND PROCESS FOR RETOUCHING DYE IMAGES
摘要 PHOTOGRAPHIC MATERIAL AND PROCESS FOR RETOUCHING DYE IMAGES A method of retouching a dye image comprises selective removal with an aqueous acidic organic solvent solution of a portion of a dye image from an exposed and processed photographic silver halide element comprising a support bearing a dye image from a dye-forming coupler and a primary amine photographic color developing agent, wherein the dye-forming coupler: (a) contains no ionizable group that is retained as part of a dye formed upon oxidative coupling, (b) has a structure such that the Log P of the coupler is greater than 4 and is derived from a four-equivalent coupler that has a Log P less than 8, and (c) hag a coupling reactivity that enables formation of maximum image density of at least 0.5. The method comprises the step of contacting the dye image with an aqueous acidic organic solvent solution for a time and at a temperature sufficient to selectively dissolve and remove a portion of the dye image from the photographic element. A new photographic element designed for such retouching comprises new pyrazolotriazole couplers.
