Abstract: PURPOSE:To eliminate the influence of oxygen on a reaction of a polymerizable compd. in a photosensitive layer by heating the sensitive material at above a specified temp. as it contains a specified amt. of water in the photosensitive layer, and developing the sensitive material. CONSTITUTION:A photosensitive layer contg. a silver halide, reducing agent, and a polymerizable compd.(e.g. ethylenic unsatd. polymerizable compd.) is formed on a base body of a photosensitive material. After or simultaneously with image-exposure of the sensitive material, 10-400wt.%(basing on the amt. of the polymerizable compd.) of liquid such as water, etc., is incorporated into the photosensitive layer, and the photosensitive layer is heated at >=50 deg.C.
