Silver halide photosensitive materials for color photography

Abstract

Abstract Wherein Y1 and Y2 each stand for a non-metallic atomic group necessary for forming a nitrogen-containing heterocyclic ring nucleus selected from the group consisting of pyrroline, thiazoline, thiazole, benzothiazol, naphthothiazole, selenazole benzoselenazole, naphthoselenazole, oxazole, benzoxazole, naphthoxozole, imidazole, benzimidazole, pyridine, and quinoline, which heterocyclic ring nucleus may be substituted by a halogen atom, a lower alkyl group, a lower alkoxy group, or an aryl group, which group may be substituted by a halogen atom, a lower alkyl group or a lower alkoxy group; R1 stands for a lower alkyl group, a hydroxyalkyl group, or a sulfoalkyl group; R2 is a hydrogen atom or a lower alkyl group; A designates an alkylene group or a group -(CH2)2 -O -(CH2)2 -or, -(CH2)2-O -CH2CH(OH) CH2-; and n1 and n2 are each 0 or 1. A silver halide photosensitive material for color photography providing excellent color reproducibility is disclosed which comprises a support and at least three emulsion layers supported thereon; said layers being a red-sensitive emulsion layer, a green-sensitive emulsion layer, and a blue-sensitive emulsion layer; the blue-sensitive emulsion layer containing a sensitizing dye represented by the following formula:
