Abstract:
Single-side coated silver halide photographic film material, comprising a support, at least one light-sensitive emulsion layer and a substantially light-insensitive protective hydrophilic colloid layer farther away from said support than said emulsion layer, wherein said emulsion layer contains a silver halide emulsion rich in silver bromide with cubic crystals having an average numerical diameter in the range from 0.4 up to 0.8 &mgr;m, wherein at least 95 mole % of bromide ions are present, and wherein said hydrophilic colloid layer or another substantially light-insensitive hydrophilic colloid layer comprises a hydrazide represented by the general formula (I): wherein in the general formula (I) Y is selected from the group consisting of wherein R1 to R7 is selected from the group consisting of hydrogen, NR8R9, OR10, SR11, an aliphatic group, an aromatic group, and a heteroaromatic group, and wherein R8 to R11 each independently represents a member selected from the group consisting of hydrogen, an aliphatic group, an aromatic group, a heteroaromatic group and wherein R4 and R5, R6 and R7 and R8 and R9 respectively may have the necessary atoms in order to form a ring; n equals an integer having a value of 1 or 2; A1 and A2 each independently represents hydrogen, a group capable of yielding a hydrogen upon alkaline hydrolysis, or R12SO2, provided that, if A1 represents R12SO2, A2 represents hydrogen or vice versa, that R12 represents an aliphatic group, an aromatic group, a heteroaromatic group; and that further Ar represents an aromatic or heteroaromatic group; L represents a divalent linking group; and X represents a silver halide adsorptive group or a group capable of yielding a silver halide adsorptive group upon processing.
