| titleOfInvention | Photographic elements containing particular color couplers in combination with hydroquinone type stabilizers |
| abstract | A photographic element having at least one photosensitive silver halide layer and associated therewith both a particular type of color coupler and a particular type of stabilizer. The color coupler is of the general formula (1) or (2): ##STR1## wherein A and B represent the same or different electron-withdrawing group, n X is H or a group which splits off on coupling with oxidized color developer, n R is an alkyl, cycloalkyl, aryl or heterocyclic which may be substituted, --COR 1 , --CSR 1 , SOR 1 , SO 2 R 1 , --NHCOR 1 , --CONHR 1 , --COOR 1 , --COSR 1 , --NHSO 2 R 1 wherein R 1 is an alkyl, cycloalkyl, or aryl group any of which are optionally substituted, and wherein two or more of A, B, R, and X optionally form part of a ring, n Link is a linking group and n n is 0, 1 or 2. n The stabilizer is of the general formula: ##STR2## wherein: E 1 , E 2 , W 2 and W 3 may independently be a hydrogen atom, a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aromatic group, an acylamino group, a mono or dialkylamino group, an aliphatic or aromatic thio group, an aliphatic or aromatic oxycarbonyl group, or W 2 and W 3 in combination with the benzene ring may independently represent the atoms necessary to complete a fused ring system, or E 1 and W 3 together, and E 2 and W 2 together, may independently form a heterocyclic ring with an O. |
