Abstract

Abstract In a color diffusion transfer photographic material which comprises a photosensitive element containing at least one silver halide emulsion layer having associated therein a non-diffusible dye image-providing material, an image-receiving element for immobilizing therein diffusible dye formed by the oxidation reaction of the dye image-providing material and a primary aromatic amino color developing agent to form dye images, and a processing composition for developing the exposed silver halide in the silver halide emulsion layer and transferring the diffusible dye formed into the image-receiving layer with at least one of the photosensitive elements, the image-receiving element or the processing composition containing a primary aromatic amino color developing agent or a precursor thereof, with the photosensitive element and/or the image-receiving element of the photographic material containing at least one of divinyl sulfone and a divinyl sulfone derivative represented by the formula (I): ##STR1## wherein B represents an atomic group necessary for forming an ammonium group, a sulfonium group or a phosphonium group; X - represents an acid anion; and n is 0, 1 or 2.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 254 words
A color diffusion transfer photographic material comprising a photosensitive element containing at least one silver halide emulsion layer having associated therewith a non-diffusible dye image-providing material; an image-receiving element for immobilizing therein a diffusible dye formed by the oxidation reaction of the dye image-providing material and a primary aromatic amino color developing agent to form dye images; a processing composition for developing silver halide in the silver halide emulsion layer once the silver halide is exposed and transferring by diffusion the diffusible dye to the image-receiving element and with at least one of the photosensitive element, the image-receiving element and the processing composition containing a primary aromatic amino color developing agent or a precursor thereof; with at least one of said photosensitive element and said image-receiving element of the photographic material having incorporated therein a material which both prevents color image fading and reduces the formation of stain in blank areas which is at least one of (1) divinyl sulfone and (2) a divinyl sulfone derivative represented by the general formula: ##STR12## wherein B represents an ammonium group represented by the formula: ##STR13## wherein R 1 , R 2 and R 3 , which may be the same or different, each represents a saturated or unsaturated, straight chain or branched chain aliphatic group having 1 to 7 carbon atoms; and R 1 R 2 and R 3 may combine with each other to form a 5-membered ring or a 6-membered ring; X - represents an acid anion; and n is 0, 1 or 2.
Claim 2
Dependent Claim 254 words
A color diffusion transfer photographic material comprising a photosensitive element containing at least one silver halide emulsion layer having associated therewith a non-diffusible dye image-providing material; an image-receiving element for immobilizing therein a diffusible dye formed by the oxidation reaction of the dye image-providing material and a primary aromatic amino color developing agent to form dye images; a processing composition for developing silver halide in the silver halide emulsion layer once the silver halide is exposed and transferring by diffusion the diffusible dye to the image-receiving element and with at least one of the photosensitive element, the image-receiving element and the processing composition containing a primary aromatic amino color developing agent or a precursor thereof; with at least one of said photosensitive element and said image-receiving element of the photographic material having incorporated therein a material which both prevents color image fading and reduces the formation of stain in blank areas which is at least one of (1) divinyl sulfone and (2) a divinyl sulfone derivative represented by the general formula: ##STR12## wherein B represents an ammonium group represented by the formula: ##STR13## wherein R 1 , R 2 and R 3 , which may be the same or different, each represents a saturated or unsaturated, straight chain or branched chain aliphatic group having 1 to 7 carbon atoms; and R 1 R 2 and R 3 may combine with each other to form a 5-membered ring or a 6-membered ring; X - represents an acid anion; and n is 0, 1 or 2.
