Abstract

1, 157, 505. Coupler incorporated silver halide materials. ILFORD Ltd. Sept. 8, 1966 [Sept. 10, 1965], No.38750/65. Heading G2C. [Also in Divisions C2 and C4] Photographic material suitable for forming reversal transfer images in colour comprises, in at least one silver halide emulsion layer or an adjacent layer, a magenta dye coupler of formula wherein R is a C 1-4 alkyl group, R 1 is H, halogen or C 1-4 alkyl or alkoxy, X is-NH- or -CH 2 NH- and R 2 is a group which has a free p-position to a hydroxyl group of formula selected from
