    摘要： There are described a method for retouching photographic images, compositions adapted for such retouching, and photographic elements containing dye-forming couplers that yield dye images that particularly lend themselves to retouching by this method. The method comprises contacting a photographic element containing a dye image with a defined retouching composition to solubilize and remove selected areas or amounts of dye. The composition comprises an aqueous basic solution of a dinucleophile and a water-soluble organic co-solvent. The preferred photographic element for application of this retouching method comprises a dye image formed from a pyrazoloazole magenta dye forming coupler having a cleavable ballast group joined to the remainder of the molecule by one or two electrophilic cleavage groups. The retouching composition cleaves the ballast from the dye and solubilizes the dye, allowing it to be washed from the element.

    摘要： A method of retouching a dye image comprises selective removal with an aqueous acidic organic solvent solution, as described in the application, 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 so 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) has a coupling reactivity that enables formation of maximum image density of at least 0.6. The method comprises the step of contacting the dye image with an aqueous acidic organic solvent solution, as described in the application, 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 as described in the application.
