    • Disclosed is a silver halide color photographic material containing at least one cyan dye forming coupler of the following general formula (C-1) and at least one compound of the following general formula (I) in the same layer of the material: ##STR1## where R.sub.0 represents an alkyl group, an alkenyl group, an aryl group, or a heterocyclic group;X represents a hydrogen atom, or a group capable of being split off by a coupling reaction with the oxidation product of an aromatic primary amine color developing agent; andAr represents an aromatic group; ##STR2## where R.sub.1, R.sub.2 and R.sub.3 each represent an aliphatic group, an aryl group, or a heterocyclic group;R.sub.4 represents a hydrogen atom, an aliphatic group, an aryl group, or a heterocyclic group;R.sub.1 and R.sub.2, or R.sub.3 and R.sub.4 may be bonded to each other to form a 5-membered to 8-membered ring along with the nitrogen atom in the formula;the compound of formula (I) may form a dimer or a higher polymer at the position of R.sub.1, R.sub.2, R.sub.3 or R.sub.4 ;provided that R.sub.1 and R.sub.3, or R.sub.2 and R.sub.4 are not bonded to each other to form a ring, and that the sum of the carbon atoms of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is 6 or more.
    • 公开了在同一层材料中含有至少一种以下通式(C-1)的青色染料形成成色剂和至少一种以下通式(I)的化合物的卤化银彩色照相材料:(* CHEMICAL 结构*)(C-1)其中R 0表示烷基,烯基,芳基或杂环基; X表示氢原子或能够通过与芳族伯胺显色剂的氧化产物的偶联反应而分裂的基团; Ar表示芳香族基团。 (*化学结构*)(I)其中R 1,R 2和R 3各自表示脂族基,芳基或杂环基; R4表示氢原子,脂族基,芳基或杂环基; R 1和R 2,或者R 3和R 4可以彼此键合以与式中的氮原子一起形成5元至8元环; 式(I)化合物可以在R 1,R 2,R 3或R 4的位置上形成二聚体或更高级的聚合物; 条件是R1和R3或R2和R4彼此不结合形成环,并且R 1,R 2,R 3和R 4的碳原子之和为6以上。
