<p>The purpose of the present invention is to provide a resin composition for a laser-engravable flexographic printing plate, which enables the production of a flexographic printing plate having excellent non-tackiness, excellent hardness, excellent printing resistance and an excellent halftone pattern and has excellent removability of engraving dusts produced during the laser engraving of an original plate for a printing plate. The resin composition for a laser-engravable flexographic printing plate according to the present invention is characterized by comprising: (a component (A)) a polyurethane resin having a group represented by formula (1); (a component (B)) an ethylenically unsaturated compound; and (a component (C)) a polymerization initiator. In formula (1), R and R" independently represent a hydrogen atom or an alkyl group; R' represents an alkyl group; R and R' may be linked together to form a ring; and a wavy line represents a bonding position.</p> |
