Abstract

1323466 Colour photographic silver halide materials FUJI PHOTO FILM CO Ltd 7 Sept 1970 [5 Sept 1969] 42802/70 Heading G2C Photographic light-sensitive colour material contains at least two silver halide emulsion layers sensitive to different regions of the spectrum and, in addition in at least one layer, which may be an emulsion layer or a layer adjacent thereto, a merocyanine dye of the general formula:- where X is S, O, Se or a group = N-R 3 ; R 1 , R 2 and R 3 are H, substituted or unsubstituted alkyl or aryl; and Z completes a substituted or unsubstituted heterocyclic ring, which dye increases the colour contrast of the image by the inter-image effect.
