A silver halide color photographic light-sensitive material comprising a support having coated thereon at least one silver halide emulsion layer, the color photographic light-sensitive material having at least one layer containing at least one 2-equivalent magenta coupler of the 5-pyrazolone type represented by the following general formula (I): ##STR1## wherein W represents a phenyl group substituted with at least one substituent selected from the group consisting of a halogen atom, an alkyl group, an alkoxy group, an alkoxycarbonyl group and a cyano group; Y represents an acylamino group or an anilino group; and Z represents a group capable of being released upon coupling, and at least one compound represented by the following general formula (II): ##STR2## wherein R.sup.1 and R.sup.2, which may be the same or different, each represents a hydrogen atom, an alkyl group or an aryl group, provided that both R.sup.1 and R.sup.2 do not represent hydrogen atoms at the same time; Z.sup.1 represents a methine group, a substituted machine group or the group --N.dbd.; and Q represents an atomic group which contains a nitrogen atom, a sulfur atom or an oxygen atom and is necessary to form a 5-membered or a 6-membered heterocyclic ring together with the group ##STR3## The silver halide color photographic light-sensitive material can provide an excellent magenta color image without the occurrence of stain, even when the color photographic material is processed in a processing solution under the running condition.
一种银卤化物彩色感光材料,包括一种支撑体,其上涂覆有至少一层银卤化物乳剂层,该彩色感光材料具有至少一层,其中包含至少一种5-吡唑酮类2当量品红偶联剂,其由以下通式(I)表示:##STR1## 其中W表示苯基,其上取代有至少一种取自卤素原子、烷基、烷氧基、烷氧羰基和氰基的取代基;Y表示酰胺基或苯胺基;Z表示能够在偶联时释放的基团,以及至少一种由以下通式(II)表示的化合物:##STR2## 其中R1和R2,可以相同或不同,分别表示氢原子、烷基或芳基,但是当R1和R2不同时,两者都不能同时表示氢原子;Z1表示亚甲基基团、取代亚甲基基团或基团-N.dbd.;Q表示一个原子团,其中包含一个氮原子、一个硫原子或一个氧原子,并且必须与基团##STR3## 一起形成一个5元或6元杂环环。该银卤化物彩色感光材料可以在处理液中运行条件下处理,而不发生污点,并提供优异的品红色图像。
