Abstract (en)
[origin: EP0887703A1] Light- sensitive silver halide color photographic multilayer material which comprises a support base having coated thereon at least a blue light sensitive silver halide emulsion layer, associated with yellow dye forming couplers, containg a) a yellow dye forming DIR coupler having a 1,2,4-triazolyl group attached to the coupling position, from which the 1,2,4-triazolyl group is released during development, such 1,2,4-triazolyl group comprising an alkoxy- or aryloxy-carbonyl hydrolizeable group attached to a benzylthio substituent on the 1,2,4-triazolyl group, and b) a yellow dye forming malonodiamino DIR coupler in the coupling position having a group which supplies a compound with development inhibiting properties when the group is released from the coupling position during development, wherein said group is a 4,7-dihalogen-2-benzotriazolyl group.
