    • PURPOSE:To obtain a photosensitive material capable of forming a yellow dye image high in sensitivity and developed color density by incorporating a specified photographic yellow coupler and a specified phenol derivative in a photographic constituent layer. CONSTITUTION:The photographic constituent layer contains the photographic cyan coupler represented by general formula [I] and the phenol derivative represented by general formula [II], thus permitting high sensitivity and high color density and good spectral absorption characteristics to be obtained and deterioration of color developing performance of the cyan coupler to be avoided even if a color developing soln. deprived of benzyl alcohol is used. In formulae [I], [II], R1 is alkyl or aryl; R2 is a monovalent group; Z is H or a group releasable at the time of the coupling reaction with the oxidation product of a color developing agent; l is an integer of 1-3 and when it is 2 or 3, each of R2 may be same or different; R3 is alkyl, alkenyl, cycloalkyl, aryl, alkoxy, or amino; R4 is a monovalent group; and n is an integer of 0-3, and when it is 2 or 3, each of R4 may be same or different.
    • 目的:为了获得能够形成高感光度的黄色染料图像的感光材料,并且通过将特定的照相黄色成色剂和特定的苯酚衍生物掺入照相构成层中而得到显色浓度。 构成:照相构成层含有由通式[I]表示的照相青色成色剂和通式[II]表示的苯酚衍生物,因此可以获得高灵敏度和高色密度以及良好的光谱吸收特性并降低颜色 显影青色成色剂的性能即使是显色溶液也要避免。 不使用苄醇。 在式[I],[II]中,R 1是烷基或芳基; R2是一价基团; Z是H或与彩色显影剂的氧化产物偶联反应时可释放的基团; l为1-3的整数,当为2或3时,R 2可以相同或不同; R3是烷基,烯基,环烷基,芳基,烷氧基或氨基; R4是一价基团; 并且n为0-3的整数,当为2或3时,各R4可以相同或不同。

    • PURPOSE:To provide a silver halide color photographic sensitive material giving stabilized yellow image by incorporating a stabilizer which causes no change in hue, produces no fog, and is well effective in improving the fastness of a yellow dye image without hindering dispersin or producing crystals into a photographic layer. CONSTITUTION:At least one kind of compound represented by general formula IIand at least one kind of compound represented by general formula I are incorporated into a layer contg. at least one kind of yellow coupler reprensted by general formula I (where X1 is a group which can be eliminated during a coupling reaction with the oxidized product of a developing agent) or at least one layer adjacent to said layer. The light and heat fasteness of a yellow dye image can be improved.
    • 目的:提供一种卤化银彩色照相感光材料,通过并入不会改变色调的稳定剂,产生不起雾的作用,可以有效地提高黄色染料图像的牢度,而不会妨碍分散或产生晶体 照相层。 构成:由通式II表示的至少一种化合物和至少一种通式I表示的化合物引入层中。 至少一种由通式I表示的黄色成色剂(其中X1是在与显影剂的氧化产物的偶联反应期间可以除去的基团)或与所述层相邻的至少一层。 可以改善黄色染料影像的光热耐热性。
