Abstract

Abstract A silver halide photographic material is disclosed, comprising a hydrophilic layer containing a dye dispersed in a solid particle form therein on at least one side of a support and at least one silver halide emulsion layer, wherein the coating weight of hydrophilic colloid in said layer containing a dye dispersed in a solid particle form therein is from 0.05 to 0.5 g/m 2 and the total coating weight of hydrophilic colloid on each side of said support is from 0.5 to 3 g/m 2 .

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 161 words
A silver halide photographic material comprising a hydrophilic colloid layer containing therein a dye dispersed in a solid particle form on at least one side of a support and at least one silver halide emulsion layer, wherein the coating weight of hydrophilic colloid in said hydrophilic colloid layer containing therein a dye dispersed in a solid particle form is from 0.05 to 0.5 g/m 2 and the total coating weight of hydrophilic colloid on each side of said support is from 0.5 to 3 g/m 2 , wherein said material comprises at least one undercoat layer comprising a first undercoat layer which contains polymers on a surface of said support and a second undercoat layer which contains hydrophilic colloid on the first undercoat layer, and said second undercoat layer is said hydrophilic colloid layer containing therein a dye dispersed in a solid particle form, and wherein said polymers are selected from the group consisting of styrene-butadiene copolymers and vinylidene chloride copolymers.
Claim 2
Dependent Claim 161 words
A silver halide photographic material comprising a hydrophilic colloid layer containing therein a dye dispersed in a solid particle form on at least one side of a support and at least one silver halide emulsion layer, wherein the coating weight of hydrophilic colloid in said hydrophilic colloid layer containing therein a dye dispersed in a solid particle form is from 0.05 to 0.5 g/m 2 and the total coating weight of hydrophilic colloid on each side of said support is from 0.5 to 3 g/m 2 , wherein said material comprises at least one undercoat layer comprising a first undercoat layer which contains polymers on a surface of said support and a second undercoat layer which contains hydrophilic colloid on the first undercoat layer, and said second undercoat layer is said hydrophilic colloid layer containing therein a dye dispersed in a solid particle form, and wherein said polymers are selected from the group consisting of styrene-butadiene copolymers and vinylidene chloride copolymers.
Claim 3
