A silver halide photographic light-sensitive element which comprises at least one silver halide emulsion layer and at least one hydrophilic colloid layer containing at least one dye represented by the following formula (I): ##STR1## wherein R represents a hydrogen atom, an aliphatic hydrocarbon group, an aromatic hydrocarbon group or an aralkyl group; X represents a hydrogen atom, a halogen atom, an aliphatic hydrocarbon group, an alkoxy group, an alkylthio group or a substituted amino group; L represents a methine group; M represents a cation; and p represents an integer of 1 to 3. The dyes are useful in antihalation and filter layers, and can be decolorized readily and completely.
一种银卤化物照相感光元件,包括至少一层银卤化物乳胶层和至少一层含有至少一种由下式(I)表示的染料的亲水胶体层:##STR1## 其中R代表氢原子、脂肪烃基、芳香烃基或芳基烃基;X代表氢原子、卤素原子、脂肪烃基、烷氧基、烷基硫基或取代氨基;L代表亚甲基基团;M代表阳离子;p代表1至3的整数。这些染料在抗光晕和滤光层中很有用,可以轻松完全地脱色。
