FLEXOGRAPHIC PLATE MATERIAL

摘要

PROBLEM TO BE SOLVED: To avoid a tacky surface of a flexographic plate material having a water-developable synthetic rubber-containing photosensitive resin layer, to improve adhesion of an original film to the photosensitive layer particularly in exposure and to obtain a photosensitive resin plate for flexographic printing excellent in image reproducibility. SOLUTION: A coating comprising a mixture of a partially saponified polyvinyl acetate and a rubber latex and a coating comprising a partially saponified polyvinyl acetate having 60-90% saponification degree are successively formed in 0.2-20 μm total thickness on the surface of a flexographic plate material having a water-developable synthetic rubber-containing photosensitive resin layer.
