Abstract

1512040 Sensitizing silver halide emulsions FUJI PHOTO FILM CO Ltd 3 Nov 1975 [5 Nov 1974] 45696/75 Heading G2C [Also in Division C4] Silver halide photographic emulsion is sensitized by the incorporation of a dye of Formula I wherein R<SP>1</SP> is -L-(SO 3 M) k ; L is an alkylene group optionally substituted with at least one hydroxy group, phenyl group or a halogen atom wherein the carbon atoms in the straight chain alkylene portion are not more than 5 or is an arylene group optionally substituted with at least one of a halogen atom, an alkyl or alkoxy group having 1 to 4 carbon atoms or a hydroxy, phenoxy, amino, carboxy, or sulpho group; M is a hydrogen atom or an atom or group capable of forming a salt; R<SP>2</SP> is a hydrogen atom or a methyl group; R<SP>3</SP> is an alkyl or alkoxy group; k is 1 or 2; m is 0 or 1; n is 0, 1 or 2; and the dye is incorporated in an amount of 0À005 to 50g per mole of silver halide. The dye provides spectral sensitization and inherent sensitivity increasing effects, increases the sharpness and resolving power of the emulsion, and is rapidly decolored in photographic processing.
