Title: Lithographic printing plate and its manufacture
Inventor: IMAI YUKA
IPC: B41N1/14
Filed: 1991-02-19
Abstract: PURPOSE:To obtain a waterless lithographic printing plate which can be manufactured directly based on a digital signal by thermally printing an image part of a thermal recording layer consisting of a binder resin, silane coupling agent and thermal melting material on a plate sheet on which an ink-repellent layer of silicone rubber is provided. CONSTITUTION:An ink repellent layer 2 is formed on a plate sheet by applying a blend of silicone rubber and toluene on a support 1 and thermally drying it. Then a mixed liquid of binder resin, silane coupling agent, a thermal melting material and toluene is applied on a base sheet 4 and then is thermally dried to provide a thermal recording layer 3 on a thermal recording sheet. The plate sheet is stacked on the thermal recording sheet in such a manner that the ink repellent layer 2 is positioned opposite to the thermal melting layer 3. Next, a thermal head 5 is used for scanning in accordance with digital information to perform thermal printing. After thermal printing, if the thermal recording sheet is removed from the plate sheet, the thermal recording layer 3 in a part where thermal printing takes place remains as an image part as said layer 3 sticks molten to the ink repellent layer 2 of the plate sheet. Thus a waterless lithographic printing plate is obtained.
