Abstract

1324046 Light-sensitive silver halide photographic material KONISHIROKU PHOTO INDUSTRY CO Ltd 19 April 1971 [20 March 1970] 24745/71 Heading G2C A photographic element comprising a support carrying a layer of a light sensitive silver halide emulsion, contain in a layer or layers thereof (A) at least one compound of the formula:- wherein R 1 is 1-5C alkyl or sulphoalkyl, hydroxyalkyl, or alkoxycarbonylalkyl the alkyl portions having 1-5C or phenylcarbonylmethyl; R 2 is alkyl or alkenyl each having 1-5C or sulphoalkyl, hydroxyalkyl, carboxyalkyl, alkoxycarbonylalkyl, acyloxyalkyl, phenyl or sulpho- or carboxysubstituted phenyl; Z 1 forms with N-(CH=CH) n -C a 5-or-6-membered ring; Z 2 forms with C-CO-N a 5-membered ring; and n is 0 or 1; and (B) at least one compound of the formula:- wherein R 4 and each of R 5 and R 6 are H, alkyl, alkenyl, aryl or aralkyl. The element may additionally contain a spectrally sensitising dye in at least one silver halide emulsion layer. The compound of the above general formulae may be present in a coupler containing layer. Many examples of these compounds are given. These elements produce colour images having low graininess.
