Abstract
A heat-developable light-sensitive material including a support and at least one light-sensitive silver halide emulsion layer provided on the support, the light-sensitive silver halide emulsion layer containing light-sensitive silver halide grains, a compound to form a dye through coupling reaction with an oxidized product of a developing agent, and a binder, characterized in that the light-sensitive silver halide emulsion layer includes an emulsion containing a developing agent and tabular silver halide grains having a mean grain thickness of 0.01-0.07 .mu.m. The light-sensitive material enables to provide a convenient and quick method of forming color images.
Claims23
A heat-developable light-sensitive material comprising a support and at least one light-sensitive silver halide emulsion layer provided on the support, the light-sensitive silver halide emulsion layer containing light-sensitive silver halide grains, a developing agent, a compound to form a cyan, magenta, or yellow dye through a coupling reaction with an oxidized product of the developing agent, and a binder, wherein the light-sensitive silver halide emulsion layer comprises an emulsion containing tabular silver halide grains having a mean grain thickness of 0.01-0.07 .mu.m.
A silver halide color light-sensitive material comprising a first support and a first photographic constitutive layer provided thereon by way of coating and including at least one light-sensitive layer, the light-sensitive layer containing light-sensitive silver halide grains, a compound to form a cyan, magenta, or yellow dye through a coupling reaction with an oxidized product of a developing agent, and a binder, wherein the silver halide color light-sensitive material, after exposure, is adhered to a processing material comprising a second support and a second photographic constitutive layer provided on the second support and including a processing layer, in the presence of water between the surface of the light-sensitive layer and the surface of the processing layer in an amount of 10% to 100% that required to maximally swell the layers of the materials, and subsequently heated to form an image in the silver halide color light-sensitive material, wherein at least one light-sensitive layer of the silver halide color light-sensitive material comprises an emulsion containing tabular silver halide grains each of which has an average equivalent circle diameter of at least 0.7 .mu.m, and a mean thickness of less than 0.07 .mu.m.
A method of forming color images comprising the steps of:
- exposing a silver halide color light-sensitive material comprising a first support and at least one light-sensitive layer provided on the first support, the light-sensitive layer containing light-sensitive silver halide grains, a compound to form a cyan, magenta, or yellow dye through a coupling reaction with an oxidized product of a developing agent, and a binder;
- feeding water to the light-sensitive layer surface of the light-sensitive material and/or the processing layer surface of a processing material comprising a second support and a processing layer provided on the second support;
- adhering the light-sensitive layer surface and the processing layer surface to each other;
- and
- heating the resultant assembly to thereby form an image in the light-sensitive material;
- wherein the silver halide color light-sensitive material contains a silver halide emulsion containing tabular silver halide grains having an average equivalent circle diameter of at least 0.7 .mu.m and a mean thickness of less than 0.7 .mu.m in at least one light-sensitive layer;
- and
- the silver halide color light-sensitive material contains either one of a slightly-soluble metal compound or a compound capable of increasing pH through a complex-forming reaction with a constituent metal ion of the slightly-soluble metal compound, while the processing material contains the other.
