Heat sensitive composition, original plate using the same for lithographic printing plate, and process for preparing printing plate |
摘要 |
A heat-sensitive composition is disclosed which includes a substance which absorbs light and generates heat, an anionic self water-dispersible resin particle having an acid value of 10 to 300 and an average particle diameter of 0.005 to 15 mum, and a fluorine base surfactant. An original plate for a lithographic printing plate is disclosed which includes an ordinary negative- or positive-type PS plate having coated thereon the heat-sensitive composition. The original plate is image-wise exposed with high energy density light based on digital image information from a computer, subjected to first development with an aqueous alkali solution, flood exposure with active light, a second development with a developer for a negative or a positive, and post-treatment to obtain a printing plate.
