Abstract
1,045,777. Supersensitizing dye combinations. ILFORD Ltd. April 13,1965 [April 20, 1964], No. 16271/64. Heading G2C. A photographic silver halide emulsion contains a sensitizing dye of formula: – where Y and Z are S,Se, -NR 12 or -CH = CH-,R 1 and R 3 are alkyl, carboxyalkyl, carbamoyl alkyl or sulphoalkyl. R 2 is H or alkyl 1-4C, R 5 ,R 6 ,R 9 and R 10 are H, halogen, alkyl, aryl, substituted aryl, alkoxy, alkoxy alkoxy or trifluoromethyl groups, R4 and R8 are hydrogen or together with R 5 and R 9 form part of benzene ring, R 7 and R 11 are hydrogen or together with R 6 and R 10 form part of a benzene ring, R 12 is alkyl, aryl or substituted aryl and n is o or 1 and X is an anion, together with a dye of general formula:- where R 4 – R 11 are as above, R 13 and R 14 are alkyl 1-4C,A is -O-or -NR 17 ,R 16 and R 17 are hydrogen, alkyl, aralkyl or substituted aryl and when n in the first formula is o either U or V must be an oxygen atom, the other is oxygen or sulphur and when n in the first formula is 1, U and V are the same and are oxygen or sulphur. Aryl groups may be substituted by alkyl, alkoxy or halogen.
