PRINTING PLATE MATERIAL AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a printing plate material which has a light-absorbing layer having sufficient strength as a component and excels in plate wear resistance, and a manufacturing method thereof. SOLUTION: The printing plate material is manufactured by a method having a process that a layer containing a light-absorbing material and silicon oxide is formed on a base and sintered at a firing temperature of 500-1,000°C, preferably 600-800°C, in the atmosphere of partial pressure of oxygen of 10-3Torr or below, preferably 10-4Torr or below, and thereby the light-absorbing layer absorbing at least part of incident light and converting it into heat is formed, and a process that a photocatalyst layer is formed on the light-absorbing layer.
