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.
摘要翻译：一种卤化银照相感光材料，其中选择性地染色特定层并且不扩散到其它层中的高度不变的新型亚芳基双型染料被并入亲水性胶体层中。在感光材料中使用的染料可以在照相处理时容易地去除，并且不会不利地影响照相乳剂的照相性质，特别是光谱增感。

摘要： A silver halide light-sensitive material is disclosed, comprising a support having provided thereon a silver halide emulsion layer that has been infrared-sensitized so as to have a sensitivity maximum at a wavelength longer than 750 nm and at least one light-insensitive hydrophilic colloidal layer on said silver halide emulsion layer, wherein said light-insensitive hydrophilic colloidal layer contains at least one dye having an absorption maximum at a wavelength shorter than 750 nm. The material has high sensitivity to infrared light, but can be handled under bright safelight.

摘要： A silver halide photographic light-sensitive material comprising a support having thereon at least one light-sensitive silver halide emulsion layer and a light-insensitive uppermost layer is disclosed. The light-insensitive uppermost layer has a melting time longer than that of the light-sensitive silver halide emulsion layer and the thickness of the light-insensitive uppermost layer is from 1.3 .mu.m to 5.0 .mu.m. The silver halide photographic light-sensitive material has an improved covering power and results in remarkably low degree of reticulation. Furthermore, when the material is used it results in a reduced amount of scum being formed in the processing solution.
