Abstract

1319967 Sensitising photographic silver halide emulsions AGFA-GEVAERT AG 10 Sept 1970 [12 Sept 1969] 43291/70 Heading G2C Photographic silver halide emulsions are super-sensitised by adding (i) a dye of the formula: - wherein X is O, S or Se, R is H or alkyl, cycloalkyl or aryl which may be substituted, R 1 and R 2 are each amino which may be mono- or di-substituted with alkyl of up to 6C, cycloalkyl, aralkyl or aryl, or the nitrogen of which may form part of a 5, 6 or 7 membered heterocyclic ring, R 3 and R 4 are each H, alkyl or alkoxy of up to 6C and A is an anion, together with (ii) a compound of the formula:- Q-Z-SH wherein Z is a carbocyclic aromatic ring or a substituted or unsubstituted 5 or 6 membered heterocyclic ring to which benzene or naphthalene rings may be condensed, and Q is an acid group (i.e. one containing a labile proton) attached directly or via vinylene to Z, which acid group may be in salt form, and includes acidic sulphonamide groups. The compound has a supersensitising effect on the dye, and the emulsion is sensitised in the green region.
