摘要： A silver halide photographic light-sensitive material, in which a highly immobile novel arylidene bis type of dye which selectively dyes a specific layer and does not diffuse into other layers is incorporated in a hydrophilic colloidal layer. The dye used in this light-sensitive material can be easily removed upon photographic processing, and does not adversely affect photographic properties, particularly spectral sensitization, of the photographic emulsions.
