PURPOSE:To obtain a high density image free from fog by incorporating at least two kinds of specified compds. CONSTITUTION:At least one kind of compd. represented by formula I and at least one kind of compd. represented by formula II are incorporated. In the formula, X1 is a residue of a photographic retarder, L1 is a simple bonding radical or a bivalent group and A is H atom, amino group or a salt thereof, sulfo group or a salt thereof. In the formula II, X2 is a residue of a photographic retarder, L2 is a bivalent group and B is a ballast group. Thus, a high density image free from fog can be obtd. |
