Abstract
1,137,580. Super-sensitized photographic silver halide emulsions. FUJI SHASHIN FILM K.K. Dec.30, 1966 [Dec.30, 1965], No.58381/66. Heading G2C. A photographic silver halide emulsion is supersensitized by (i) at least one dye of the formula: - where R 1 and R 2 are each substituted or unsubstituted alkyl or aryl, allyl or aralkyl, R is alkyl or allyl, R 3 is hydrogen, alkyl or aryl, Y and Y' each complete a heterocyclic ring, Q is oxygen or sulphur, X is an anion, n 1 , n 2 and n 3 are each 0 or 1 and n is 1 or 2, n being 1 when the dye forms an internal salt, and (ii) at least one condensate of formaldehyde and a hydroxy-benzene compound of the formula; - where R 4 and R 5 are each -OH, -OM, -0R 6 , - NH 2 , -NHR 6 , -N(R 6 ) 2 , -NHNH 2 or -NHNHR 6 , where R 6 is alkyl or 1-8 carbons, aryl or aralkyl, and M is alkali-metal or alkaline earth metal and n 4 and n 5 are each 1, 2, or 3. The condensate preferably has 2-10 units. The usual additives may be present.
