ABSTRACT:
A method for processing a silver halide photographic element comprising carrying out developement processing, including a washing step, of an imagewise exposed silver halide photographic element, wherein the washing step is carried out at 45.degree. C. or less for 90 sec. or less, and wherein the silver halide color photographic element comprises a support having provided thereon at least one silver halide emulsion layer, wherein the silver halide photographic element contains in a hydrophilic colloid layer, from 2 mg/m.sup.2 to 40 mg
.sup.2 of at least one dye represented by the following general formula (I): ##STR1## wherein R.sub.1 and R.sub.2, which can be the same or different, can each represents --COOR.sub.5, or ##STR2## R.sub.3 and R.sub.4, which can be the same or different, each represents a hydrogen atom or an alkyl group, R.sub.5 and R.sub.6, which can be the same or different, each represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, and R.sub.1 and R.sub.2 represent --COOR.sub.5 and R.sub.5 represents a hydrogen atom, R.sub.1 and R.sub.2 represent a carboxyl group which can form a salt, R.sub.5 and R.sub.6 can combine together to form a 5- or 6-membered ring, Q.sub.1 and Q.sub.2, which can be the same or different, each represents a substituted or unsubstituted aryl group, X.sub.1 and X.sub.2, which can be the same or different, each represents a divalent linking group or a bond, Y.sub.1 and Y.sub.2, which can be the same or different, each represents a sulfo group or a carboxyl group which can form a salt, L.sub.1, L.sub.2 and L.sub.3, which can be the same or different, each represents a substituted or unsubstituted methine group, m.sub.1 and m.sub.2 each is 1 or 2, n is 0, 1 or 2, p.sub.1 and p.sub.2 each is 0, 1, 2, 3, or 4, and s.sub.1 and s.sub.2 each is 1 or 2.
