摘要： A silver halide photographic material has at least one silver halide emulsion layer spectrally sensitized by spectral sensitizing dye(s), in which the silver halide emulsion layer contains in the hydrophilic dispersion medium a hydrophilic polymer having a cationic structure or a dispersion of the hydrophilic polymer and a luminous dye having a relatively weak adsorptive property to silver halide and simultaneously satisfying the conditions 1), 2), and 3), with the proviso that the light-collecting dye and the spectral sensitizing dye may be the same compound. The conditions are:
1) the equilibrium adsorption amount of the dye in an aqueous 5% gelatin solution containing silver bromide the outer surface of which is substantially composed of a {III} plane is not more than 10- 6 mole/m 2 per surface area of the silver bromide at a temperature of 40 °C, pH of 6.5 ±0.05, and a dye concentration in solution phase of 10- 4 mole/liter; 2) the luminous quantum yield of the dye is at least 0.1 at room temperature and at a concentration in dry gelatin of 10- 4 mole/dm 3 ; and 3) the dye has a luminous band at least partially overlapping the optical absorption band of the adsorptive spectral sensitizing dye on the silver halide.摘要翻译： 卤化银照相材料具有至少一个通过光谱增感染料光谱增感的卤化银乳剂层，其中卤化银乳剂层在亲水性分散介质中含有具有阳离子结构的亲水性聚合物或亲水性聚合物的分散体 以及对卤化银具有较弱吸附性并且同时满足条件1），2）和3）的发光染料，条件是光收集染料和光谱增感染料可以是相同的化合物。 条件是：1）在其外表面基本上由{III}平面构成的包含溴化银的5％明胶水溶液中染料的平衡吸附量不大于每表面积10-6摩尔/ m2 的溴化银在40℃的温度，6.5±0.05的pH和10-4摩尔/升的溶液相中的染料浓度; 2）染料的发光量子产率在室温下至少为0.1，并且在干明胶中的浓度为10-4摩尔/ dm3; 和3）染料具有至少部分与卤化银上的吸收光谱增感染料的光吸收带重叠的发光带。

摘要： A silver halide photographic light-sensitive material is disclosed. The material is comprised of a transparent support having provided on one side of the support at least two silver halide emulsion layers and a surface-protecting layer. One of the two silver halide emulsion layer is a tabular silver halide emulsion layer containing tabular silver halide grains having a diameter at least five times the thickness of the grains. The other silver halide emulsion layer is a non-tabular silver halide emulsion layer containing non-tabular silver halide grains. The tabular silver halide emulsion layer is positioned closer to the support than the non-tabular silver halide emulsion layer, and the non-tabular silver halide emulsion layer is positioned closer to the support than the surface-protecting layer. The material may include two similar silver halide emulsion layers and a surface-protecting layer on the opposite side of the support. The material provides images with improved sharpness without a decrease in sensitivity while effectively utilizing the amount of silver.
