COLOUR PHOTOPGRAPHIC MATERIAL FOR THE SILVER-DYE BLEACHING PROCESS, PROCESS FOR THE PRODUCTION OF THIS MATERIAL AND ITS USE IN THE PRODUCTION OF PHOTOGRAPHIC IMAGES

摘要

A color-photographic recording material for the silver dye bleach process, which contains oil-soluble azo dyes of the formula IMAGE in which R1 is hydrogen, alkyl, alkoxy, alkenyl, acyl, carbalkoxy, acylamino, carbamide, sulfonamide, alkylsulfone, arylsulfone, aryloxy, arylsulfonic acid ester, hydroxyl, cyano, nitro or halogen, R2 is hydrogen, alkyl, alkoxy, carbalkoxy, carbamide, sulfonamide, alkylsulfone, arylsulfone, aryloxy, cyano, nitro or halogen, R3 is hydrogen, alkyl, alkoxy, phenoxy, sulfonamide, alkylsulfone, sulfonic acid ester, cyano, nitro, halogen, carbalkoxy, carbamide or phosphoric acid diester, R4 is hydrogen, alkyl, alkoxy, carbalkoxy, carbamide, sulfonamide, acylamino, alkylsulfone, arylsulfone, hydroxyl, cyano, nitro or halogen, R5 is hydrogen, alkyl or carbalkoxy, X1 is hydrogen, alkyl, alkoxy, acylamino, alkylsulfonamide or hydroxyl, Y1 is hydrogen, alkyl, alkoxy, amino, carbalkoxy, arylsulfonamide, acylamino, halogen, hydroxyl or phosphamic acid ester, Z1 is hydrogen, alkyl, alkoxy, acylamino, acyl, carbalkoxy, alkylsulfonamide or halogen or forms a ring with Y1, and W1 is hydrogen, alkyl, alkoxy or halogen. The substituents mentioned can, where relevant, themselves be further substituted. The oil-soluble azo dyes are easily incorporated into silver halide gelatin emulsions and are very stable therein. Because of the good oil-solubility of the azo dyes, very thin layers can be cast in producing photographic materials, and this has an advantageous effect on, for example, the image sharpness.
