PROBLEM TO BE SOLVED: To obtain a photosensitive material in which a base precursor is haradly deposited by laminating a specified hardenable layer, a photosensitive layer, an image formation promoting layer and an overcoat layer on a substrate. SOLUTION: A hardenable layer 2, a photosensitive layer 3, an image formation promoting layer 4 and an overcoat layer 5 are successively laminated on an aluminum substrate 1. The hardenable layer 2 contains a polymerizable compound 21 and a crosslinkable polymer 22. The photosensitive layer 3 contains silver halide grains 31, a reducing agent 32 and a hydrophilic polymer 33. The image formation promoting layer 4 contains a base precursor 41 and a hydrophilic polymer 42. The overcoat layer 5 contains a surfactant 51 having an anionic hydrophilic group and a nonionic hydrophilic group and a hydrophilic polymer 52. The anionic hydrophilic group is, e.g. a sulfonic acid group or a sulfuric ester group. The nonionic hydrophilic group is, e.g. a hydroxyl group, a polyalkylene oxide bond, an ester bond or an amido bond. |
