Abstract
A color diffusion-transfer photographic light-sensitive material provided with at least two light-sensitive silver halide emulsion layers, each of which is combined with a non-diffusive dye image forming compound forming or releasing a diffusive dye or its precursor in relation to silver development, or with a dye image forming compound whose diffusibility changes in relation to silver development, on a support, the light-sensitive material comprises a specific hydrazine compound and a specific compound improved in storability.
Claims4
A color diffusion-transfer light-sensitive material comprising, on a support, at least two light-sensitive silver halide emulsion layers, which are combined with a non-diffusive dye image forming compound that forms or releases a diffusive dye or its precursor in association with silver development, or with a dye image forming compound whose diffusibility changes in association with silver development, wherein the light-sensitive material comprises a compound represented by the following formula (I) and a compound represented by the following formulae (III)
- wherein, R20 represents an aliphatic group, an aromatic group or a heterocyclic group;
- R10 represents a hydrogen atom or a block group;
- G10 represents —CO—, —COCO—, —C(═S)—, —SO2—, —SO—, or —PO(R30)— (in which R30 is selected from the same range of the groups as defined for R10, and R30 may be different from R10) or an iminomethylene group;
- and A10 and A20 each represent a hydrogen atom, or one of A10 and A20 represents a hydrogen atom and the other represents a substituted or unsubstituted alkylsulfonyl group, a substituted or unsubstituted arylsulfonyl group, or a substituted or unsubstituted acyl group;
- wherein, Het represents an adsorptive group to a silver halide, provided that the group represented by Het is substituted with at least one —(Q)k2—(Hy), where Q represents a divalent connecting group that comprises an atom or atomic group containing at least one of a carbon atom, a nitrogen atom, a sulfur atom, and an oxygen atom;
- and Hy represents a group having a hydrazine structure represented by R1R2N—NR3R4, where each of R1, R2, R3 and R4 independetly represent an alkyl group, an alkenyl group, an alkinyl group, an aryl group, or a heterocyclic group, and R1 and R2, R3 and R4, R1 and R3, or R2 and R4 may respectively bond to form a ring, provided that at least one of R1, R2, R3 and R4 is an alkylene group, an alkenylene group, an alkinylene group, an arylene group, or a divalent heterocyclic residue, to be substituted by —(Q)k2—(Het)k1;
- k1 and k3 independently denote 1, 2, 3 or 4, and k2 denotes 0 or 1;
- wherein the compound represented by formula (III) is added to a silver halide emulsion layer or a non-light-sensitive layer.
