Abstract
Abstract Silver halide photographic materials containing at least one 3anilino-2-pyrazol-5-one type non-diffusing magenta coupler, the phenyl group of the coupler being substituted, in at least one ortho-position thereof, with a halogen atom or an alkyl, aryl, alkoxy, aryloxy, alkylthio, arylthio, amino, amido, hydroxyl, cyano or nitro group, and in at least one of the meta- and the para-positions thereof, with a sulfamoyl group. The photographic materials containing the magenta coupler(s) are suitably prepared according to an oil solution system. A sharp color image can be reproduced from the photographic material according to a color subtractive process.
