Abstract

1,226,562. Colour photographic material. FILMFABRIK WOLFEN VEB. March 25, 1968, No. 14164/68. Heading G2C. A colour photographic material comprising a plurality of silver halide emulsion layers sensitive to different regions of the spectrum, contains (1) a colour coupler and (2) a red-sensitive silver halide emulsion containing as screening dyestuff a Cu, Ni, Cr, A1 or Fe phthalocyanine dyestuff substituted in different benzo rings with 2 R 1 and 2 R 2 groups (in which R 1 is SO 3 X, R 2 is SO 2 NHR 4 ; R 4 is H or optionally substituted alkyl or aryl; X is H, K, Na or NH 4 ).
