Abstract
1,083,049. Photographic silver halide emulsions. FUJI SHASHIN FILM KABUSHIKI KAISHA. July 28, 1965 [July 28, 1964], No.32366/65. Heading G2C. A silver halide emulsion for use in a colour negative process using a p-phenylenediamine colour developing agent contains (I) a pyrazolone coloured coupler having in its 4 position an -N=NR group where R is a substituted or unsubstituted aryl or heterocyclic group, (II) a fog inhibitor which is a colourless coupler being a pyrazolone having in its 1 position a phenyl group substituted by an -SO 2 M or -CO 2 M group where M is H, NH 4 or an alkali-metal, and optionally (III) a masking control agent of formula wherein R 1 is a substituted or unsubstituted alkyl, acylamino N-arylamino or sulphonamido group; R 2 is a substituted or unsubstituted phenyl, naphthyl or heterocyclic group; and X 5 , X 6 and X 7 are each a substituted or unsubstituted alkyl, alkylcarbamyl, alkoxy, aryloxy, sulphonamide, acylamino, hydrogen or halogen radical. Preferred colour couplers (I) have the formula and preferred colourless couplers (II) have the formula wherein R 1 and R 2 are as defined above, X 4 is a -CO 2 M or -SO 3 M group, M is as defined above, and X 1 and X 2 are each a group listed under X 4 to X 7 .
