Abstract
Abstract A silver halide color photographic material comprising a support having thereon, in succession, a 1st silver halide photographic light-sensitive emulsion layer, a photographic auxiliary layer, and a 2nd silver halide photographic light-sensitive emulsion layer, or comprising a support having on one side thereof a 1st silver halide light-sensitive layer and on the other side thereof a photographic auxiliary layer and a 2nd silver halide photographic light-sensitive layer, the photographic auxiliary layer having a spectral reflectance of higher than 20% in a wavelength range of 410 nm to 700 nm and a spectral transmittance of higher than 5% in the same wavelength range. The invention provides a color photographic material giving recorded images, etc., capable of viewing by both reflected light and transmitted light.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A silver halide color photographic light-sensitive material comprising a support having thereon, in succession, a 1st silver halide photographic light-sensitive emulsion layer, a photographic auxiliary layer, and a 2nd silver halide photographic light sensitive emulsion layer, or a support having on one side thereof a 1st silver halide photographic light-sensitive emulsion layer and on the other side thereof, in succession, a photographic auxiliary layer and a 2nd silver halide photographic light-sensitive emulsion layer, said photographic auxiliary layer comprising a hydrophilic colloid having dispersed therein at least one kind of white pigment having a mean particle size of 0.1 to 1.0μ in an amount of at least 10% by weight, having a thickness of 0.5 to 5μ, having a spectral reflectance of not less than 20% in a wavelength range of 410 nm to 700 nm and having a spectral transmittance of not less than 5% in said wavelength range.
Claim 2
Dependent Claim
149 words
A silver halide color photographic light-sensitive material comprising a support having thereon, in succession, a 1st silver halide photographic light-sensitive emulsion layer, a photographic auxiliary layer, and a 2nd silver halide photographic light sensitive emulsion layer, or a support having on one side thereof a 1st silver halide photographic light-sensitive emulsion layer and on the other side thereof, in succession, a photographic auxiliary layer and a 2nd silver halide photographic light-sensitive emulsion layer, said photographic auxiliary layer comprising a hydrophilic colloid having dispersed therein at least one kind of white pigment having a mean particle size of 0.1 to 1.0μ in an amount of at least 10% by weight, having a thickness of 0.5 to 5μ, having a spectral reflectance of not less than 20% in a wavelength range of 410 nm to 700 nm and having a spectral transmittance of not less than 5% in said wavelength range.
Claim 3
Dependent Claim
45 words
