PHOTOSENSITIVE RESIN COMPOSITION FOR FLEXOGRAPHIC PRINTING

摘要

Disclosed is a photosensitive resin composition for flexographic printing which has high water developability and good mechanical strength. The resin composition comprises (A) a partially crosslinked copolymer prepared by a radical emulsion polymerization of a specific monomer mixture (B) a linear polymer having a molecular weight of at least 5,000, which has at least 30 mol % of a conjugated diene unit, (C) a basic nitrogen atom-containing compound, (D) a photopolymerizable ethylenically unsaturated monomer, and (E) a photopolymerization initiator. The present invention also provides a resin plate for flexographic printing obtained from the above mentioned resin composition and a process for preparing it. The present invention further provides a printing plate obtained from the resin plate and a process for preparing it.
