ABSTRACT:
A silver halide color photographic light-sensitive material comprising a support having thereon photographic constituent layers comprising at least three silver halide emulsion layers each having a spectral sensitivity different from one another and containing yellow, magenta and cyan color forming couplers, respectively and a light-insensitive hydrophilic colloid layer, wherein the cyan color forming coupler is at least one dye forming coupler represented by the formula (I) shown below, at least one of the silver halide emulsion layers containing the cyan color forming coupler contains a silver halide emulsion composed of high silver chloride content grains having a silver chloride content of 80 mol % or more, and the high silver chloride content grains are tabular silver halide grains having (100) faces as major faces: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 each represents a hydrogen atom or a substituent; Z represents a non-metallic atomic group necessary for forming a ring, which may be substituted; X represents a heterocyclic group, a substituted amino group or an aryl group; Y represents a hydrogen atom or a substituent; and R.sub.6 represents a substituent.
The silver halide color photographic light-sensitive material is rapidly processable, has less dependence on processing conditions and provides a color image having excellent image quality and sharpness. It is also suitable for scanning exposure using a semiconductor laser as a light source. A method of forming a color image comprising subjecting the silver halide color photographic light-sensitive material to scanning exposure is also disclosed.
