Abstract
Abstract A silver halide light-sensitive material for color filter is disclosed, comprising a support having provided thereon at least three silver halide emulsion layers containing couplers and having color sensitivities different from each other and at least light-insensitive interlayer, wherein the total amount of the binder in the silver halide light-sensitive material is from 3 to 10 g/m 2 , the equivalent ratio of silver halide to couplers in each silver halide emulsion layer is from 1 to 2, and the average grain size (in the case of tabular grains, determined by the thickness) in each silver halide emulsion is from 0.05 to 0.9 μm, or wherein the proportion of organic compounds other than polymers to all organic compounds in each silver halide emulsion layer is 55 % by weight or less. Also disclosed are a preparation method of a color filter using the silver halide light-sensitive material and a color filter prepared according to the method.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
A method for preparing a color filter having a pixel pattern composed of blue, green and red colors, comprising subjecting a silver halide light-sensitive material to pattern exposure, color development and desilvering, the silver halide light-sensitive material comprising a support having provided thereon at least three silver halide emulsion layers containing couplers and having color sensitivities different from each other and at least one light-insensitive interlayer, wherein the total amount of binder in the silver halide light-sensitive material is from 3 to 10 g/m 2 , the equivalent ratio of silver halide to couplers in each silver halide emulsion layer is from 1 to 2, and the average grain size of silver halide (in the case of tabular grains, determined by the thickness) in each silver halide emulsion is from 0.05 to 0.9 μm.
Claim 2
Independent Claim
134 words
