Abstract
A color light sensitive material can be rapidly processed and is suitable for both surface exposure and high intensity scanning exposure. The exposed light sensitive material has excellent sharpness and residual color. The silver halide color photographic light sensitive material has on a support at least one silver halide emulsion layer containing a yellow dye forming coupler, at least one silver halide emulsion layer containing a magenta dye forming coupler, and at least one silver halide emulsion layer containing a cyan dye forming coupler. The characteristic colors of yellow, magenta and cyan are obtained using exposures according to a logarithmic relationship.
