Colour photographic material for dark stability for high dye yield

摘要

The material comprises: (a) a base with blue-, green- and red-sensitive Ag halide emulsion layer(s) contg. yellow, magenta and cyan couplers respectively; and (b) light-insensitive layers, where: (i) blue-sensitive layer contg. yellow coupler contg. an N-substd. acrylamide (deriv.) of formula (I) in combination with a phenol of formula (II) : R1, R2 = H or Me; R3 = alkyl or aryl; R4 = H, alkyl or aryl; or R3 and R4 = gp. forming a 5-8-membered ring, R3 is sec. or tert. alkyl or 2-substd. or 2,6-di-substd. aryl if R4 is H; R11, R15 = H or R13; R12, R14 = H, alkyl, acyl or alkoxy; and R13 = alkyl, acyl, acylamino or alkoxy, and adjacent gps. R11-R15 are gp. forming a 5-6-membered ring.
