PURPOSE:To obtain a photosensitive material at a low cost by coating superposedly and simultaneously at least one photosensitive coating liquid and at least one coating liquid contg. an electron ray-curing compd. on a base having a hydrophilic surface. CONSTITUTION:At least two kinds of non-aqueous coating liquids of which at least one is the photosensitive coating liquid and the coating liquid contg. the electron ray-curing compd. is coated on the base having the hydrophilic surface and thereafter electron rays are irradiated thereto to form a photosensitive layer, by which the photosensitive material for lithographic printing plate is obtd. At least one coating liquid of the above-described non-aqueous coating liquids is required to have >=50cps, more preferably >=80cps viscosity. The electron rays are so irradiated as to attain 150-300kV acceleration voltage and 0.08-7Mrad absorption dose. A metallic sheet, plastic film, etc. are used for the blank material of the base. |
