Abstract
Abstract A silver halide color photographic light-sensitive material is disclosed. The material is improved in a developing stability, whose red density-green density balance is hardly affected even by change in a developing condition. The photographic material comprises a support and, provided on a side of the support, at least one red-sensitive silver halide emulsion layer and at least one green-sensitive silver halide emulsion layer. The total thickness of the layers provided on the emulsion coated side of the suport, is within the range of from 5 to 18 μm. The red-sensitive emulsion layer contains a cyan-dye forming coupler and a clored cyan-dye forming coupler, and a ratio of the colored cyan-dye forming coupler to the total amount of the cyan-dye forming coupler and the colored cyan-dye forming coupler is within the range of from 15 to 80 mol %.

Claim 1
Independent Claim
115 words
A silver halide color photographic light-sensitive material comprising a support having, on a side thereof, plural layers including at least one red-sensitive silver halide emulsion layer and at least one green-sensitive silver halide emulsion layer, in which the total thickness in a dry state of said plural layers is within the range of from 5 to 18 μm, and said red-sensitive silver halide emulsion layer contains a non-diffusible cyan-dye forming coupler and a colored non-diffusible cyan-dye forming coupler and a ratio of said colored non-diffusible cyan-dye forming coupler to the total amount of said non-diffusible cyan-dye forming coupler and said colored cyan dye-forming coupler is within the range of from 15 to 80 mole %.
Claim 2
Dependent Claim
115 words
A silver halide color photographic light-sensitive material comprising a support having, on a side thereof, plural layers including at least one red-sensitive silver halide emulsion layer and at least one green-sensitive silver halide emulsion layer, in which the total thickness in a dry state of said plural layers is within the range of from 5 to 18 μm, and said red-sensitive silver halide emulsion layer contains a non-diffusible cyan-dye forming coupler and a colored non-diffusible cyan-dye forming coupler and a ratio of said colored non-diffusible cyan-dye forming coupler to the total amount of said non-diffusible cyan-dye forming coupler and said colored cyan dye-forming coupler is within the range of from 15 to 80 mole %.
Claim 3
Dependent Claim
47 words
