Abstract
Abstract There are disclosed a light-sensitive silver halide color photographic material having a light-sensitive silver halide emulsion layer containing at least one kind of cyan dye forming couplers represented by the formula [I] or the formula [II] as defined in the specification provided on a reflective support, and a light-sensitive silver halide color photographic material further having a green-sensitive silver halide emulsion layer containing at least one kind of magenta couplers represented by the formula [III] as defined in the specification. The light-sensitive silver halide color photographic materials according to this invention have excellent color forming characteristics and form very fast dyes to heat, light and humidity.
