ORIGINAL LITHOGRAPHIC PRINTING PLATE, PRINTING METHOD USING THIS ORIGINAL PLATE AND MICROCAPSULE

摘要

PROBLEM TO BE SOLVED: To provide a microcapsule which does not deteriorate a heat-fusible substance showing a lipophilic nature or a hydrophobic precursor to be encapsulated, an original printing plate which does not produce a large amount of waste paper at the time of start of printing and shows outstanding resistance to plate wear and a printing method using the original printing plate.

SOLUTION: This original lithographic printing plate uses the microcapsule encapsulating the heat-fusible substance with a lipophilic nature or a hydrophobic precursor with a wall material on a hydrophilic support. The wall material contains an ultraviolet absorbing agent.
