| 摘要 | PURPOSE:To render wettability characteristics of recorded image parts changeable in the distribution of a form corresponding to a pattern by patternwise, in accordance with image information, by exposing a plate surface uniformly coated with a substance changed in polarity by light irradiation. CONSTITUTION:A recording medium is prepared by spin coating a quartz substrate with a soln. obtained by mixing and dissolving 1pt. basic violet-3-leucohydroxide in a mixed soln. of 1pt. polymethyl methacrylate (PMMA) and 10pts. dichloromethane under a yellow safety light. A transparent negative original is brought into contact with said medium and irradiated with a light emitted from a 500W superhigh pressure mercury lamp through a UV-D35 filter at a distance of 15cm for 10sec to obtain an image purple in the exposed parts. This is rubbed with sanitary cotton soaked with water and coated with an oily printing ink. The ink is attached only to the unexposed parts, and paper is pressed to transfer the ink to it, thus obtaining a positive image. | ||||||
