| titleOfInvention | Photographic elements in which gelatin silver halide layers contain polymers with semicarbazone or alkoxy carbonyl hydrazone groups |
| abstract | Abrasion marks by dry-friction and the tendency of producing pressure-scratches in photographic materials is reduced by incorporating in the gelatin silver halide emulsion layers polymeric compounds containing recurring units with semicarbazone or alkoxy carbonyl hydrazone groups in the side-chains. These recurring units are represented by one of the formulae: <IMAGE> wherein: A is a single bond or -CONH-alkylene-, -COO-alkylene-, or phenylene, B is a single bond or alkylene, R1 is hydrogen or methyl, R2 is hydrogen, phenyl or lower alkyl (1-4 C), R3 is -NH-COOR or <IMAGE> wherein R is lower alkyl (1-4 C) and each of R4, R5 and R6 is hydrogen or lower alkyl (1-4 C). |
