Abstract

942,934. Photographic colour materials. KODAK Ltd. Dec. 11, 1959 [Dec. 12, 1958], No. 42128/59. Heading G2C. A photographic silver halide emulsion containing a colour coupler is sensitized with a linear polymer containing thioether and/or ternary sulphonium salt groups in the linear chain, said polymer having a molecular weight of at least 250 and being substantially free from disulphide linkages. The polymeric sensitizer may be one of those described in Specification 942, 932 or one of the polyesters described in Specification 942,935. The emulsion also may contain a gold sensitizer and a sensitizer containing a labile sulphur atom. Application 25246/1911, Specifications 235,211, 541,589, 545,448, 627,814, 636,140, 649,660, 660,012, 680,488, 711,488, 736,922, 739,913, 791,219, 800,108, 873,198, 942,936, 942,938, U.S.A. Specifications 2,347,182 and 2,948,614 also are referred to.
