Light-sensitive photographic silver halide material comprising a hydrophilic colloid layer containing in dispersed state a light-absorbing merostyryl dye that corresponds to the following general formula: ##STR1## in which: R.sup.1 is hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, aralkyl or substituted aralkyl, R.sup.2 is carboxy, alkoxycarbonyl, aryloxycarbonyl, carbamoyl, ureido, sulphamoyl or one of the groups represented by R.sup.1 ; at least one of R.sup.1 and R.sup.2 being or containing carboxy or carbamoyl, R.sup.3 is hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, and when R.sup.3 is alkyl or alkoxy it stands in ortho or para in respect of the hydroxy group, which itself is in ortho or para in respect of the methine group, said merostyryl dye containing no group that renders the dye soluble in the hydrophilic colloid layer.
含有亲水性胶体层的感光银卤素材料,其中分散着一种与以下通式相对应的吸光的美洛菲染料: ##STR1## 其中:R.sup.1是氢、烷基、取代烷基、芳基、取代芳基、芳基烷基或取代芳基烷基,R.sup.2是羧基、烷氧羰基、芳基氧羰基、氨基甲酰、脲基、磺酰胺或由R.sup.1表示的其中一种基团;R.sup.1和R.sup.2中至少有一个是或包含羧基或氨基甲酰基团,R.sup.3是氢、C.sub.1-C.sub.4烷基、C.sub.1-C.sub.4烷氧基,当R.sup.3是烷基或烷氧基时,它与羟基团相对,而羟基团本身与亚甲基团相对,所述美洛菲染料不含使染料在亲水性胶体层中溶解的基团。
