Abstract
A silver halide photosensitive material for a color filter comprising at least three silver halide emulsion layers having different spectral sensitivities and each silver halide emulsion layer contains couplers which form blue, green and red by coupling reaction with the oxidation product of a developer, wherein the amount of the couplers in a red coloring layer is adjusted so that each transmission density of the yellow and magenta dye components measured when all the couplers in the red coloring layer are subjected to color development is 1.5 or more, and a black matrix part becomes substantially black of transmission density of 2.5 or more when all the couplers on a support are subjected to reaction.
