A method for processing a silver halide color photographic material including the step of developing the silver halide color photographic material with a color developing solution containing at least one aromatic primary amine developing agent and at least one hydrazide represented by the following formula (I) or (II) R.sup.1 --X.sup.1 --NHNH--R.sup.2 (I) in which X.sup.1 represents --CO--, --SO.sub.2 -- or ##STR1## R.sup.1 represents a hydroxyl group, a hydroxyamino group, carbamoyl group, a hydrazinocarbonyl group, an amino group, or a hydrazino group; and R.sup.2 represents a hydrogen atom, an alkyl group, or an aryl group; provided that the R.sup.1 or R.sup.2 groups of at least two of the hydrazide groups may be linked to form a dimer or higher polymer of the hydrazide. R.sup.3 --X.sup.2 --NHNH--R.sup.4 (II) in which X.sup.2 represents --CO-- or --SO.sub.2 --; R.sup.3 represents a hydrogen atom, an alkyl group, an aryl group, a heterocyclic group, an alkoxy group, or an aryloxy group; and R.sup.4 represents a hydrogen atom, an alkyl group or an aryl group; provided that the R.sup.3 or R.sup.4 groups of at least two of the hydrazide groups may be linked to form a dimer or higher polymer of the hydrazide. The method provides increased developer stability and reduced fog formation, particularly in continuous processing.
一种处理银卤化物彩色照相材料的方法,包括以下步骤:用含有至少一种芳香族原始胺显影剂和至少一种由以下公式(I)或(II)表示的肼类化合物的显色显影溶液显影银卤化物彩色照相材料。其中,X1代表—CO—、—SO2—或##STR1##,R1代表羟基、羟基氨基、氨甲酰基、肼甲酰基、氨基或肼基;R2代表氢原子、烷基或芳基;但至少两个肼基的R1或R2基团可连接形成肼的二聚体或更高聚合物。R3—X2—NHNH—R4(II)其中,X2代表—CO—或—SO2—,R3代表氢原子、烷基、芳基、杂环基、烷氧基或芳氧基;R4代表氢原子、烷基或芳基;但至少两个肼基的R3或R4基团可连接形成肼的二聚体或更高聚合物。该方法提供了增加显影剂稳定性和减少雾化现象的效果,特别是在连续处理中。
