FLEXOGRAPHIC PRINTING ORIGINAL PLATE AND WATER-DEVELOPABLE LAMINATE OF PHOTOSENSITIVE RESIN

摘要

The present invention provides a water-developable laminate of photosensitive resin for letterpress printing original plate by which finer pattern can be reproduced excellently upon making a plate and printing. The flexographic printing original plate being developable by water according to the present invention is characterized in that at least a support, a photosensitive resin layer containing 25% by mass or more of latex having gelation degree of 55% or more and an adhesion-preventing layer are successively laminated, and that the adhesion-preventing layer contains a cellulose derivative. The water-developable laminate of photosensitive resin according to the present invention is characterized in that at least a support, an adhesive layer, a photosensitive resin layer containing a water-soluble polymer compound and an adhesion-preventing layer are successively laminated, and that the adhesion-preventing layer contains a cellulose derivative.
