Abstract
1377013 Super-sensitized silver halide emulsions; colour materials KONISHIROKU PHOTO INDUSTRY CO Ltd 26 Sept 1972 [27 Sept 1971] 44309/72 Heading G2C A light-sensitive photographic silver halide emulsion has a super-sensitizing combination for the green region comprising a dye of formula:- in which R 1 and R 3 each represent alkyl (1-3C) or sulphoalkyl; R 2 represents H or alkyl (1-3C); Y 1 , Y 2 , Y 3 , Y 4 , Y 5 and Y 6 each represent H, halogen, alkyl (1-3C), alkoxy (1-3C) or phenyl, or Y 2 together with either Y 1 or Y 3 ; and/or Y 5 together with either Y 4 or Y 6 complete a naphthoxazole nucleus, X is an anion and n is 0, when R 3 is sulphoalkyl, or 1; and at least one compound of formula:- in which R 4 is alkyl (1-3C), hydroxyalkyl, carboxyalkyl or sulphoalkyl, Z completes an oxazole, benzoxazole, naphthoxazole, benzimidazole, thiazoline, thiazole, benzothiazole, naphthothiazole, indolenine or pyrroline nucleus which may be substituted by halogen, alkyl (1-3C), alkoxy (1-3C), phenyl or hydroxy and Q completes a rhodanine, thiohydantoin or 2- thio-oxazolidinedione which may be substituted by hydroxyalkyl, alkoxyalkyl, carboxyalkyl, sulphoalkyl, alkyl (1-3C), alkenyl (1-3C), phenyl or halogen substituted phenyl. The emulsion may also contain 4-hydroxy-6-methyl- 1, 3, 3a, 7- tetrazaindene as an anti-foggant. Example 3 describes a colour material in which a magenta coupler 1-(3-carboxyphenyl)-3- (4-stearoyl-aminophenyl)-5-pyrazolone is used in combination with a green super-sensitizing combination as described above.
