A silver halide color photographic material comprising a support having coated thereon at least one silver halide emulsion layer, the silver halide color photographic material containing a photographic cyan dye forming coupler represented by the following general formula (I): ##STR1## wherein R.sub.1 represents an aliphatic group, an aromatic group, heterocyclic group or a substituted amino group; R.sub.2 and R.sub.3, which may be the same or different, each represents an aliphatic group, an aromatic group or a heterocyclic group, or R.sub.2 and R.sub.3 may combine with each other to form a ring; and X represents a group capable of beiing released upon an oxidative coupling with a developing agent (including a hydrogen atom). The photographic cyan dye forming coupler has a high color forming rate and provides a high maximum color density even when a color developing solution which does not contain benzyl alcohol is used, and exhibits substantially no reduction in color density in the case of processing in a bleaching solution having a weak oxidation power or an exhausted bleaching solution. The silver halide color photographic material containing the photographic cyan dye forming coupler can provide color images having excellent fastness and color reproducibility and less stain in white background area.
一种银卤化物彩色感光材料,包括支撑物,其上至少涂覆有一层银卤化物乳剂层,所述银卤化物彩色感光材料包含以下通式(I)所表示的一种光敏青色染料形成偶合剂:
其中,R1代表脂肪族基,芳香族基,杂环基或取代氨基;R2和R3,可以相同也可以不同,分别代表脂肪族基,芳香族基或杂环基,或R2和R3可以结合形成环;X代表能够在氧化偶联反应中被释放的基团(包括氢原子)。所述光敏青色染料形成偶合剂具有高的染色速率,即使使用不含苯甲醇的彩色显影液,也能提供高的最大染色密度,并且在弱氧化能力或用过的漂白液处理时,几乎不会减少染色密度。含有光敏青色染料形成偶合剂的银卤化物彩色感光材料可以提供具有优异耐久性和色彩再现性的彩色图像,并且在白色背景区域几乎不会出现污渍。
