Abstract
Abstract A photosensitive material comprises a photosensitive layer and a polymerizable layer which are laminated. An area of the polymerizable layer, corresponding to an unexposed area of the photosensitive layer, is polymerized when the photosensitive material is exposed to light with a wavelength of 400 to 900 nm and heated to 60 to 80°C.
