Abstract
PURPOSE:To obtain a direct positive image with a high max. image density and a high resolving power by incorporating a compd. which releases a specified fogging agent in an alkaline condition by allowing a coupling reaction or an oxidation-reduction reaction with the oxidant of a developing agent at the time of developing, in at least one layer of the titled material. CONSTITUTION:The compd. which releases the fogging agent shown by formula I in the alkaline condition by allowing the coupling reaction or the oxidation- reduction reaction with the oxidant of the developing agent at the time of developing, is incorporated in at least one layer of the titled material. In formula I, A is a group capable of accelerating the absorption to silver halide, L is a divalent connecting group, (l) is 0 or 1, Q' is a substrate removed a prescribed hydrogen radical from a quarternary salt type nucleus forming agent. Thus, the direct positive color photosensitive material with the high max. image density and the high resolving power can be obtd.
