Claims22
A processing method of a light-sensitive silver halide color negative film photographic material which comprises, after image-wise exposure, subjecting a light-sensitive silver halide color photographic material to a color developing, bleaching and fixing processing, followed by washing or stabilizing processing, the improvement wherein a fixing solution used in the fixing processing contains a water-soluble surfactant selected from the group consisting of surfactants represented by formula (I) and (V) presented below, said surfactant being present in an amount of 0.05 to 10 g/l, and an amount of thiosulfate in the range of 0.2 mole/liter to 3.0 mole/liter;
- and, during processing, the fixing solution is replenished in an amount of 20 to 1000 ml per 1 m.sup.2 of the light-sensitive material;
- Formula (I):
- A.sub.2 --O--(B).sub.m --(C).sub.n --X.sub.1 (I)
- wherein A.sub.2 represents a monovalent organic group selected from the group consisting of an alkyl group having 6 to 50 carbon atoms, and an aryl group substituted by an alkyl group having 3 to 35 carbon atoms or by an alkenyl group having 2 to 35 carbon atoms, and X.sub.1 is hydrogen;
- Formula (V):
- ##STR56## wherein M represents an alkali metal, n is 1 to 100, A.sub.2 represents a monovalent organic group selected form the group consisting of an alkyl group having 6 to 20 carbon atoms, and an aryl group substituted by an alkyl group having 3 to 20 carbon atoms,
- B or C is ethylene oxide or propylene oxide, or ##STR57## wherein n.sub.1, m.sub.1 and l.sub.1 each represent 0, 1, 2 or 3;
- and
- m and n each represent an integer of 0 to 100.
