    • 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. ##STR1## 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; ##STR2## wherein R.sub.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.sub.22 and R.sub.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.
    • 公开了含有由通式[I]表示的成色剂和至少一种由通式[XII]表示的化合物中的至少一种的卤化银照相材料。 式(I)其中Z是完全含氮杂环所必需的一组非金属原子,其中由Z形成的环可以被取代; X是氢原子或与彩色显影剂的氧化产物反应而释放的取代基,R是氢原子或取代基; 其中R 21为氢原子或选自烷基,烯基,环烷基和芳基的基团,R 22和R 23独立地选自烷基, 基,烯基,环烷基和芳基。 照相材料提供高度稳定的抗热和光的染料图像,并且防止在非图像区域形成污点。
