Abstract
Abstract A color image forming process is described, which comprises developing an imagewise exposed silver halide color photographic material with a color developer containing an aromatic primary amine developing agent and being substantially free of benzyl alcohol for a period of up to about 2 minutes and 30 seconds, wherein the silver halide color photographic material comprises a reflective support having thereon a blue-sensitive silver halide emulsion layer containing a yellow color-forming coupler, a green-sensitive silver halide emulsion layer contaning a magenta color-forming coupler, and a red-sensitive silver halide emulsion layer containing a cyan color-forming coupler in this order, the material further containing light-insensitive hydrophilic colloid layers between the blue-sensitive silver halide emulsion layer and the green-sensitive silver halide emulsion layer and between the green-sensitive silver halide emulsion layer and the red-sensitive silver halide emulsion layer and at least one light-insensitive hydrophilic colloid layer on the red-sensitive silver halide emulsion layer, the volume ratio of the oil component to the hydrophilic colloid in each of the light-insensitive layers is at most about 0.2 and both the light-insensitive layer between the green-sensitive silver halide emulsion layer and the red-sensitive silver halide emulsion layer and the light-insensitive layer on the red-sensitive silver halide emulsion layer each contains at least one ultraviolet absorbent compound represented by formula (F): ##STR1## wherein R 1 , R 2 , R 3 , R 4 and R 5 , which may be the same or different, each may represent a hydrogen atom or a substituent, and the R 4 and R 5 may bond together to form a 5-membered or 6-membered aromatic ring.
