Title:

PHOTOSENSITIVE PRINTING ORIGINAL PLATE

Document Type and Number:

Japanese Patent JP3765404

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To obtain a photosensitive printing original plate having good image reproducibility without causing warpage of the plate by exposure shrinkage.
SOLUTION: The photosensitive printing original plate comprises at least (A) a flexible supporting body, (B) a photosensitive resin layer and (C) an IR ablation layer. The photosensitive resin layer (B) contains a polymer binder, an ethylenic unsaturated compound and a photoinitiator composition. The warpage rate of the photosensitive printing original plate before irradiation of active rays is within ±2%, and the change in the warpage rate after irradiation of active rays is ≤15%.
