Silver halide color photographic light-sensitive material, phenidone compound for use therein, and method of producing the same

摘要：

There is disclosed a silver halide color photographic light-sensitive material that is improved in such aspects as fastness of dye images, color reproduction, cyan stain, processing cyan color contamination, and the like, by the combination use of a phenidone compound having a specific structure as in the following general formula (VIII) and a pyrrolotriazole cyan coupler. The phenidone compound (VIII) can be produced industrially in low cost, by reacting an &agr;-alkyl or alkenyl acrylate with a compound represented by the following general formula (VII): wherein, R4, R5, R6, R7, R8, and R9, each represent a hydrogen atom, an alkyl group, or the like; R2a represents an alkyl group having 6 to 30 carbon atoms, or the like.

摘要（中）：

公开了一种卤化银彩色照相感光材料，其通过组合使用具有特定的染料图像的菲啶酮化合物在染色图像的牢度，色彩再现，青色染色，加工青色污染等方面得到改善结构如以下通式（VIII）和吡咯并三唑青色成色剂。通过使α-烷基或链烯基丙烯酸酯与下列通式（VII）表示的化合物反应，可以以低成本工业生产菲尼酮化合物（Ⅷ）：其中R4，R5，R6，R7，R8和R9 各自表示氢原子，烷基等; R 2a表示碳原子数6〜30的烷基等。
