    • There is disclosed a light-sensitive photographic material which comprises a silver halide emulsion layer containing a first coupler dispersed in oil droplets, a second coupler dispersed in an alkali aqueous solution and a compound capable of releasing a diffusible development inhibiting substance or a precursor thereof.The specified combination of the first and the second couplers with the diffusible DIR coupler according to the present invention provide a good inter image effect whereby color images having excellent color balance are obtained. The first coupler is preferably selected from compounds of the formula (II), (III), (IV), (V), (VI), (VII) (VIII) which contain at least one lipophilic substituent; and the second coupler is preferably selected from compounds of the formula (IV), (V), (VI), (VII), or (VIII) which do not contain a lipophilic substituent: ##STR1##
    • 公开了一种感光照相材料,其包含含有分散在油滴中的第一成色剂的卤化银乳剂层,分散在碱性水溶液中的第二成色剂和能够释放扩散显影抑制物质或其前体的化合物。 根据本发明的第一和第二耦合器与可扩散DIR耦合器的指定组合提供了良好的图像间效果,由此获得具有优异色彩平衡的彩色图像。 第一成色剂优选选自含有至少一个亲脂取代基的式(II),(III),(IV),(V),(VI),(VII)(VIII) 并且第二成色剂优选选自不含亲脂性取代基的式(IV),(V),(VI),(VII)或(VIII)的化合物:(IMAG) (VIII)(VIII)(VIII)图像(VI)<图像>(VII)
