Resin composition for laser-engravable flexographic printing plate, flexographic printing plate precursor for laser-engravable and process for producing same, and flexographic printing plate and process for making same

Abstract

To provide a resin composition for a laser-engravable flexographic printing plate that has excellent removability for engraving residue generated when laser-engraving a printing plate precursor and that can give a flexographic printing plate that is excellent in terms of non-tackiness, hardness, printing durability, and halftone shape. A resin composition for a laser-engravable flexographic printing plate, the resin composition that comprises (Component A) a polyurethane resin having a group represented by Formula (1), (Component B) an ethylenically unsaturated compound, and (Component C) a polymerization initiator wherein in the Formula, R and R″ independently denote a hydrogen atom or an alkyl group, R′ denotes an alkyl group, R and R′ may be linked to form a ring, and the wavy line portion denotes the position of bonding.

Dependencies are inferred from the claim text.
