Abstract
Abstract Disclosed is a silver halide color photographic light-sensitive material comprising a reflective support comprising polyolefin resin coated paper and provided on one side thereof with photographic component layers comprising a hydrophilic colloidal layer containing a white pigment, a non-sensitive hydrophilic colloidal layer, and a silver halide emulsion layer, wherein at least one of said photographic component layers contains an oil-soluble dye or a colored pigment, either of which is not substantially incapable of being decolorized on a photographic-processing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
87 words
A silver halide color photographic light-sensitive material comprising a reflective support composed of polyolefin resin-coated paper having provided on one side thereof photographic component layers comprising a hydrophilic colloidal layer containing a white pigment, a non-light-sensitive hydrophilic colloidal layer, and a silver halide emulsion layer, wherein at least one of said photographic component layers contains an oil-soluble dye or a colored pigment, neither of which substantially decolorizes upon photographic processing, an iron content of a gelatin contained in said photographic component layers being less than 5 ppm.
Claim 2
Dependent Claim
87 words
A silver halide color photographic light-sensitive material comprising a reflective support composed of polyolefin resin-coated paper having provided on one side thereof photographic component layers comprising a hydrophilic colloidal layer containing a white pigment, a non-light-sensitive hydrophilic colloidal layer, and a silver halide emulsion layer, wherein at least one of said photographic component layers contains an oil-soluble dye or a colored pigment, neither of which substantially decolorizes upon photographic processing, an iron content of a gelatin contained in said photographic component layers being less than 5 ppm.
Claim 3
Dependent Claim
26 words
The material of claim 1, wherein a coating amount of a gelatin contained in said photographic component layers is not more than 9 g/m 2 .
Claim 4
Dependent Claim
17 words
The material of claim 1, wherein said oil-soluble dye is a anthraquinone compound or an azo compound.
Claim 5
Dependent Claim
