摘要:
The object is to provide a silver halide photographic light-sensitive material containing a developing agent which can effect color developing reaction efficiently with a known coupler without being restricted by the kind of the coupler. Namely, the present invention is a silver halide photographic light-sensitive material comprising a support having thereon at least one layer comprising at least one compound represented by the following general formula (1): ##STR1## wherein, R.sub.1 to R.sub.4 represent a hydrogen atom or substituent, A represents a hydroxyl group or substituted amino group, X represents a di- or higher valent connecting group selected from --CO--, --SO--, --SO.sub.2 -- and --PO
摘要:
A silver halide color photographic light-sensitive material is disclosed, capable of forming an image by, after exposure of a light-sensitive material, supplying water corresponding to from 1/10 to 1 times the water necessary for giving maximum swelling of all coated layers of a light-sensitive material and a processing material to the light-sensitive material or the processing material, laminating these materials to each other and then heating them, the light-sensitive material comprising a support having thereon at least one photographic light-sensitive layer comprising a light-sensitive silver halide, a developing agent, a compound capable of forming a dye upon coupling reaction with an oxidation product of the developing agent and a binder, and the processing material comprising a support having thereon a processing layer containing a base and/or a base precursor, wherein at least two kinds of silver halide emulsions having spectral sensitivity in the same wavelength region and different in the average grain projected area are used in combination such that an emulsion having a larger average grain projected area has a ratio of silver halide grain numbers per unit area of the light-sensitive material larger than the ratio of the values obtained by dividing the coated silver amount of the emulsion by the 3/2nd power of average grain projected area. Also disclosed is a method for forming a color image using the same.
