Title:
WATER-DEVELOPABLE PHOTOSENSITIVE RESIN COMPOSITION FOR FLEXOGRAPHIC PRINTING, AND PHOTOSENSITIVE RESIN ORIGINAL PLATE FOR FLEXOGRAPHIC PRINTING OBTAINED FROM SAME
Document Type and Number:
WIPO Patent Application WO/2017/159199
Kind Code:
A1
Abstract:
Provided is a photosensitive resin composition for a high-quality flexographic printing original plate which is a low-hardness plate used in flexographic printing, yet has reduced adhesion of dust, dirt, and paper powder to a relief and good UV ink resistance, as well as satisfies the long-term preservability of the printing original plate. The present invention is a water-developable photosensitive resin composition for flexographic printing that contains at least (a) a polyamide and/or polyamide block copolymer, (b) a crosslinking agent having one or more unsaturated groups, (c) a photoinitiator, and (d) a fatty acid ester, wherein the water-developable photosensitive resin composition for flexographic printing is characterized in that (d) the fatty acid ester has two or more hydroxyl groups and 11-23 carbon atoms within a molecule, and the content of (d) the fatty acid ester in the photosensitive resin composition is 0.2-6% by weight.
