PURPOSE:To effectively strengthen a color image in a stable manner and without any fog by using a bath containing a special complex metal salt of organic acid and hydrogen peroxide so that the photographic material after image exposure has its color image strengthened and treated. CONSTITUTION:A metal salt of organic acid (or bleaching agent) which is prepared by coordinating a metal ion such as iron or copper is contained in a quantity of (a) about 2 to 50 g/litter together with hydrogen peroxide (or a strengthening agent) in a quantity of (b) about 0.3 to 20 g/litter in an organic acid such as aminopolycarbonic acid (e.g., ethylene diamine tetraacetate), oxalic acid or amino poly phosphate. A treating bath having a pH higher than about 8 (preferably, 10 to 14) is used to treat a color photographic material of silver halide after the exposure in the presence of an image silver and a main color developing agent. Incidentally, a solvent of silver halide such as potassium thiosulfate or thiourea is preferably used in addition. According to the present method, moreover, the quantity of the photosensitive material can be reduced to a level of about one quatter of the conventional method. |
