A silver halide photographic light-sensitive material comprising a support having provided thereon a layer containing at least one cyan dye image forming compound represented by the following formula (1):

Silver halide photographic light-sensitive material

A method for improving light fastness of an image, which comprises releasing or forming an image forming dye or a precursor thereof corresponding or counter-corresponding to silver development and allowing an image formed by transferring said image forming dye or precursor thereof to coexist with a compound represented by general formula (I) in an image forming material ##STR1## The symbols in formula (I) are defined in the description. Also disclosed is an image forming material for use in the method.

Method for improving light fastness of images, and image forming material

A pyrazolylazophenol dye exhibiting excellent spectral characteristics and having high fastness to light, heat, air or chemicals, and a color light-sensitive material containing an image forming compound comprising the dye, which releases a magenta dye exhibiting excellent spectral characteristics and having high fastness to light, heat, air or chemicals.

Pyrazolylazophenol dye

A thermal transfer recording material capable of giving a color image having an excellent color reproducibility as well as good light fastness and free from fading, bleeding and contamination of an article contacted is provided. The thermal transfer recording material comprises a thermal transfer dye donating material containing the specified thermally migratable, dissociative heteryl azo dye of phenol or naphthol type and an image receiving material for thermal transfer printing, containing at least one of basic materials and mordants as a dye receiving compound.

Thermal transfer recording material

A silver halide color photographic material is disclosed, which comprises a support having provided thereon at least one hydrophilic colloidal layer, wherein the hydrophilic colloidal layer contains a novel coupler compound having a high dye forming rate and a high color density represented by general formula (I):

Silver halide color photographic material

A silver halide color photographic material containing at least one coupler compound of the formula (1) in at least one hydrophilic colloid layer which is provided on a support:

A silver halide color photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, wherein the silver halide color photographic material comprises i) a nondiffusive coupler represented by the general formula (I) or (II): ##STR1## and ii) an acyl acetamide coupler comprising, as an acyl group, a group represented by the general formula (A) ##STR2## The silver halide color photographic material provides a high color density and exhibits a small fluctuation of photographic performance during preservation thereof and improved color image fastness and color reproducibility.

A silver halide color photographic light-sensitive material includes a support and at least one hydrophilic colloid layer formed on the support. The hydrophilic layer contains a coupler compound which is represented by formula (I) below and has a high dye formation rate and a high color forming density. This silver halide color photographic light-sensitive material can achieve an improved sharpness and a high sensitivity:

Disclosed is a silver halide color photographic material containing a silver halide emulsion having a high silver iodide content and containing a novel yellow colored cyan coupler. The material has a high sensitivity, a good graininess, an excellent color reproducibility and a sufficient sharpness. The material has at least one light-sensitive emulsion layer on a support and is characterized in that it contains at least one yellow colored cyan coupler, that the emulsion layer contains chemically sensitized silver halide grains, and that the chemically sensitized silver halide grain in the emulsion has a silver iodobromide phase with a silver iodide content of from 15 to 45 mol % as a distinctly layered structure and has a silver iodide content of more than 7 mol % based on the whole grain.

Silver halide color photographic material having a high silver iodide
