Abstract

PURPOSE:To obtain a composition with high fixing and color developing sensitivities, high contrast and high resolving power by laying a specified fixing layer, an intermediate layer and a color developing layer on a support. CONSTITUTION:On a support a fixing layer is formed consisting of a Co(III) amine and/or a Co(III) amine complex (a), a photoreducing agent (b), a hydrogen donor (c) and a dioxime chelating agent represented by formula I (where each of R1 and R2 is alkyl, aryl or aralkyl and n is 0-3) and/or a diantipyrrylmethane chelating agent (d) represented by formula II (where each of R3-5 and R'3-5 is H, alkyl or aryl and each of R6 and R7 is H, alkyl, optionally substituted aryl or aralkyl), and on the fixing layer an intermediate layer consisting of the component (a), a substance (e) having reducing power in a basic atmosphere and a water soluble resin or an emulsion resin (f) and a color developing layer consisting of a photo-oxidizing agent (g), a coupler (h) which develops color by oxidation and an acid (i) accelerating the color development are formed in order.
