Abstract
1,128,418. Sensitized photographic silver halide emulsions. FUJI SHASHIN FILM K.K. Oct.19, 1966 [Oct.22, 1965], No. 46774/66. Heading G2C. Photographic silver halide emulsions are super-sensitized with at least one dye of Formula I: - where W 1 and W 2 are halogen, R 1 and R 2 are alkyl or substituted alkyl including carboxyalkyl and sulphoalkyl, allyl, aryl or substituted aryl or aralkyl, X is an anion and n is one when an inner salt is formed or 2 when such a salt is not formed, and at least one dye of Formula II: - where R 3 is alkyl, R 4 and R 5 are selected from the same values as R 1 and R 2 , Y and Y<SP>1</SP> are each sulphur or selenium, V 1 to V 4 are each hydrogen, hydroxyl, halogen, alkyl, alkoxy or aryl, R 3 being methyl when V 1 and V 2 are both hydrogen, V 3 and V 4 are both halogen and Y and Y<SP>1</SP> are both sulphur and X and n have the values given above. In Examples, emulsions sensitized with each dye separately are compared with similar emulsions sensitized with both dyes together.
