摘要： A photographic material comprises a support bearing thereon at least one silver halide emulsion layer containing at least one non-colour-developable and diffusion-resistant phenol compound and, as phenol cyan layer, at least one compound of the formula:
wherein R 1 represents a ballast radical which endows with diffusion-resistance said phenol cyan coupler and a cyan dye produced by said coupler, Ar represents an aryl radical, and X represents hydrogen or a radical capable of splitting off upon coupling of said coupler to the oxidant of an aromatic primary amine color developing agent.-

摘要： A silver halide photographic material containing at least one of couplers represented by the general formula (I) and at least one of the compounds represented by the general formula [XII] is disclosed. Formula [I]
wherein Z is a group of nonmetal atoms necessary to complete a nitrogen-containing heterocyclic ring where the ring formed by Z may be substituted; X is a hydrogen atom or a substituent capable of being released upon reaction with the oxidation product of a color developing agent and R is a hydrogen atom or substituent;
wherein R 21 is a hydrogen atom or a group selected from the group consisting of an alkyl group, an alkenyl group, a cycloalkyl group and aryl group, R 22 and R 23 are independently selected from the group consisting of an alkyl group, an alkenyl group, a cycloalkyl group and an aryl group. The photographic material provides a dye-image highly stable against heat and light, and a formation of stain at a non-image area is prevented.摘要翻译： 公开了含有由通式（I）表示的成色剂和由通式[XII]表示的至少一种化合物中的至少一种的卤化银照相材料。 式[I]其中Z是完成含氮杂环所必需的非金属原子基团，其中由Z形成的环可以被取代; X是氢原子或能够在与彩色显影剂的氧化产物反应时释放的取代基，并且R是氢原子或取代基; 其中R 21是氢原子或选自烷基，烯基，环烷基和芳基的基团，R 22和R 23独立地选自烷基，链烯基， 环烷基和芳基。 照相材料提供对热和光高度稳定的染料图像，并且防止了在非图像区域形成污点。

摘要： There is disclosed a coupler for photography represented by the formula:
wherein R 1 represents a branched alkyl group having 3 to 5 carbon atoms: R 2 represents an aryl group; X represents a divalent linking group; Ar represents an aryl group; and Z is a hydrogen atom or a group eliminable through the coupling reaction with the oxidized product of an aromatic primary amine type color developing agent, and a light-sensitive silver halide photographic material comprising the same. The coupler mentioned above is not only excellent in solubility in organic solvents, but also can be easily purified, thus being capable of exhibiting excellent characteristics with respect to spectral absorption characteristics, sensitivity, colour density, color staining as well as with respect to image storability such as light resistance, heat resistance and humidity resistance.
