PROBLEM TO BE SOLVED: To provide a direct thermal lithographic printing original plate for offset printing which does not need development and is excellent in plate wear and non-image properties, a method for manufacturing the original plate, and a lithographic printing plate by the original plate. SOLUTION: In the lithographic printing original plate, a recording layer comprising a hydrophilic binder polymer having silanol groups, at least one kind of oxide particles whose surfaces act as acid points, and a photothermal conversion agent is formed on a support, and the binder polymer is cured through linkages with the oxide particles. |
