Abstract

1531927 Photographic 2-equivalent cyanforming couplers FUJI PHOTO FILM CO Ltd 10 June 1976 [11 June 1975] 24157/76 Heading G2C [Also in Divisions C2 and C4] A photographic cyan-forming coupler substituted in the coupling position by a group of the Formula: -O-CX-Y-R where R is an optionally substituted aliphatic, aromatic or heterocyclic residue; and X and Y, the same or different, are O or S is incorporated in a photographic silver halide material (see Ex 1-5, 7 and 8) which may be a colour diffusion transfer material (see Ex 7), or developer (see Ex 6). The coupler may be dimeric (see specified couplers 10 and 36) or coloured (see specified couplers 28-32). Specified couplers 1, 5 and 6 may be incorporated in the developer.
