Abstract
1, 157, 504. Coupler incorporated silver halide materials. ILFORD Ltd. Sept. 8, 1966 [Sept. 10, 1965], No.38749/65. Heading G2C. [Also in Division C4] Photographic materials suitable for forming transfer images in colour comprises, in at least one silver halide emulsion layer or an adjacent layer, a yellow dye coupler of formula wherein R is a C 1-4 alkyl linkage, X is a linkage n is O or 1 and R 1 is a group which has a free p-portion to a hydroxyl group of formula selected from
