Abstract
The present invention provides a diffusion transfer heat-developable color photographic light-sensitive material comprising a support having thereon at least one light-sensitive silver halide emulsion layer and a nondiffusing dye-providing compound which releases or forms a diffusive dye in response to or in counter response to a reaction by which a silver halide is reduced to silver under the presence of a reducing agent, and an organic solid pigment in at least one of light-sensitive silver halide emulsion layer and the layer(s) adjacent thereto, and a method for forming a color image using the light-sensitive material.
Claims11
A diffusion transfer heat-developable color photographic light-sensitive material comprising i) a support having thereon at least one light-sensitive silver halide emulsion layer and a nondiffusing dye-providing compound which releases or forms a diffusion dye in response to or in counter response to a reaction by which silver halide is reduced to silver in the presence of a reducing agent, and ii) a substantially water-insoluble condensed polycyclic organic solid pigment selected from the group consisting of an isoindolinone, an anthraquinone, a flavanthrone, an anthraquinone, a quinophthalone and a copper complex salt of an azomethyne and having a maximum absorption spectrum of 500 nm or less in at least one of said at least one light-sensitive silver halide emulsion layer and a layer(s) adjacent thereto.
A diffusion transfer heat-developable color photographic light-sensitive material comprising i) a support having thereon at least one light-sensitive silver halide emulsion layer and a nondiffusing dye-providing compound which releases or forms a diffusive dye in response to or in counter response to a reaction by which silver halide is reduced to silver in the presence of a reducing agent, and ii) a substantially water-insoluble organic solid pigment having a maximum absorption spectrum of 500 nm or less in at least one of said at least one light-sensitive silver halide emulsion layer and a layer(s) adjacent thereto, wherein said organic solid pigment is represented by the following general ##STR37## wherein R.sub.1 to R.sub.10 each represents a hydrogen atom, or a substituent selected from the group consisting of a halogen atom, an alkyl group, an alkoxy group, a nitro group, an acyl group, an aryl group, an aryloxy group, a sulfamoyl group, an alkylsulfamoyl group, an arylsulfamoyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, an alkylcarbamoyl group, an arylcarbamoyl group, an acylamino group, an alkylsulfonylamino group, an arylsulfonylamino group, a ureido group and group represented by the general formula (I-a):
- ##STR38## wherein R.sub.1 to R.sub.5 are as defined in the general formula (I);
- said substituents may be further substituted with at least one of these substituents;
- with the proviso that R.sub.1 and R.sub.2, R.sub.2 and R.sub.3, R.sub.3 and R.sub.4, R.sub.4 and R.sub.5, R.sub.6 and R.sub.7, R.sub.7 and R.sub.8, R.sub.8 and R.sub.9 or R.sub.9 and R.sub.10 on the same benzene ring may together form a heterocyclic ring;
- said organic solid pigment may be in a form of a bis compound formed by connecting two molecules represented by the general formula (I) via the respective R.sub.3 or R.sub.8, or via a single bond at the position of R.sub.3 or R.sub.8 on the benzene ring.
A process for forming a color image which comprises subjecting a diffusion transfer heat-developable color photographic light-sensitive material comprising i) a support having thereon at least on light-sensitive silver halide emulsion layer and a nondiffusing dye-providing compound which releases or forms a diffusive dye in response to or in counter response to a reaction by which silver halide is reduced to silver in the presence of a reducing agent, and ii) a substantially water-insoluble condensed polycyclic organic solid pigment selected from the group consisting of an isoindolinone, an anthraquinone, a flavanthrone, an anthraquinone, a quinophthalone and a copper complex salt of an azomethyne and having a maximum absorption spectrum of 500 nm or less in at least one of said at least one light-sensitive silver halide emulsion layer and a layer(s) adjacent thereto, to imagewise exposure to light, heat-developing said color photographic light-sensitive material in the presence of a reducing agent, and transferring a diffusible dye thus released or formed to an image receiving material.
