摘要： Disclosed is a positive type silver halide color photographic light-sensitive material comprising a support having thereon a mainly yellow image forming layer, a mainly magenta image forming layer and a mainly cyan image forming layer; wherein, when an exposure is conducted with 1/10 to 10 times an exposure amount giving minimum density of +0.2 on a first layer selected from said three layer after developing in the main spectra sensitivity region of the first layer, a second layer selected from said three layers is given lower density with said exposure than a density without said exposure; and after a photographic process comprising a color developing step, the mainly yellow, mainly magenta and mainly cyan image forming layers have the monochromatic yellow, magenta and cyan tones in toe portions thereof each of not less than 1.7. The silver halide color photographic light sensitive material is capable of providing a color proof improved in the approximation degrees of an image quality to a printed matter.
