Abstract

1401859 Supersensitizing silver halide emulsions KONISHIROKU PHOTO INDUSTRY CO Ltd 14 Aug 1972 [14 Aug 1971] 37840/72 Heading G2C A light-sensitive silver halide photographic emulsion is supersensitized by a combination of at least one compound of general formula:- in which R 1 and R 2 are each -CH 3 , -C 2 H 5 or substituted alkyl e.g. alkyl having 1-4C substituted by -COOH or -SO 3 M, M being H or an alkali metal atom, R 3 is -CH 3 or -C 2 H 5 , Y 1 and Y 2 are each S or Se, V 1 , V 2 , V 3 and V 4 are each H, -CH 3 , -C 2 H 5 , -OCH 3 , -OC 2 H 5 or halogen or V 1 and V 2 and/or V 3 and V 4 may together form a benzene ring; X is an anion and m is 0 or 1, and at least one compound of general formula:- in which R 4 and R 5 are each -CH 3 or -C 2 H 5 , substituted alkyl e.g. alkyl having 1-4C substituted by -SO 3 M or -COOH, or aryl, Z completes a benzoxazoline, benzothiazoline, benzoselenazoline, thiazoline or pyrroline nucleus bearing the R 4 substituent shown and which may be further substituted; and Q completes a rhodanine ring, 2- thiohydantoin ring ( which may be further substituted in addition to the R 5 substituent shown) or a 2-thiooxazolidinedione ring. The supersensitizing dye combination is particularly useful in lith-type emulsions.
