Abstract

The present invention provides a silver halide color photographic light-sensitive material including a substrate having a photographic constituent layer coated thereon including at least one light-sensitive layer which includes a light-sensitive silver halide emulsion, a developing agent, a compound capable of forming a dye by a coupling reaction with the oxidation product of the developing agent, and a binder, the light-sensitive material after the exposure thereof being put together with a processing material including a substrate having a constituent layer coated thereon including a processing layer comprising a base and/or a base precursor, in the presence of water supplied to the light-sensitive layer of the light-sensitive material or to the processing layer of the processing material in an amount ranging from 1/10 to the equivalent of an amount which is required for the maximum swelling of the entire coating layers of these materials, so that the light-sensitive layer and the processing layer face each other, and being heated for the purpose of heat development to form a color image in the light-sensitive material, in which the light-sensitive silver halide emulsion contains at least one ion selected from the group consisting of a metal ion and a metal complex ion which are each an electron trap having a depth of 0.6 eV or less, and contains at least one kind of tabular grain having an average aspect ratio ranging from 4 to 100.
