A color-photographic recording material for the silver dye bleach process, which contains oil-soluble azo dyes of the formula ##STR1## in which R.sub.1 is hydrogen, alkyl, alkoxy, alkenyl, acyl, carbalkoxy, acylamino, carbamide, sulfonamide, alkylsulfone, arylsulfone, aryloxy, arylsulfonic acid ester, hydroxyl, cyano, nitro or halogen, R.sub.2 is hydrogen, alkyl, alkoxy, carbalkoxy, carbamide, sulfonamide, alkylsulfone, arylsulfone, aryloxy, cyano, nitro or halogen, R.sub.3 is hydrogen, alkyl, alkoxy, phenoxy, sulfonamide, alkylsulfone, sulfonic acid ester, cyano, nitro, halogen, carbalkoxy, carbamide or phosphoric acid diester, R.sub.4 is hydrogen, alkyl, alkoxy, carbalkoxy, carbamide, sulfonamide, acylamino, alkylsulfone, arylsulfone, hydroxyl, cyano, nitro or halogen, R.sub.5 is hydrogen, alkyl or carbalkoxy, X.sub.1 is hydrogen, alkyl, alkoxy, acylamino, alkylsulfonamide or hydroxyl, Y.sub.1 is hydrogen, alkyl, alkoxy, amino, carbalkoxy, arylsulfonamide, acylamino, halogen, hydroxyl or phosphamic acid ester, Z.sub.1 is hydrogen, alkyl, alkoxy, acylamino, acyl, carbalkoxy, alkylsulfonamide or halogen or forms a ring with Y.sub.1, and W.sub.1 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.

染料,其中R.sub.1为氢、烷基、烷氧基、烯基、酰基、羰基酯、酰胺基、
氨基甲酰基、磺酰胺基、烷基磺酰基、芳基磺酰基、芳基氧基、芳基
磺酸酯、羟基、
氰基、硝基或卤素,R.sub.2为氢、烷基、烷氧基、羰基酯、
氨基甲酰基、磺酰胺基、烷基磺酰基、芳基磺酰基、芳基氧基、
氰基、硝基或卤素,R.sub.3为氢、烷基、烷氧基、苯氧基、磺酰胺基、烷基磺酰基、
磺酸酯、
氰基、硝基、卤素、羰基酯、
氨基甲酰基或
磷酸二酯,R.sub.4为氢、烷基、烷氧基、羰基酯、
氨基甲酰基、磺酰胺基、酰胺基、烷基磺酰基、芳基磺酰基、羟基、
氰基、硝基或卤素,R.sub.5为氢、烷基或羰基酯,X.sub.1为氢、烷基、烷氧基、酰胺基、烷基磺酰胺或羟基,Y.sub.1为氢、烷基、烷氧基、
