PROCESS FOR PRODUCING FLEXOGRAPHIC PRINTING PLATE PRECURSOR FOR LASER ENGRAVING, FLEXOGRAPHIC PRINTING PLATE PRECURSOR FOR LASER ENGRAVING, PROCESS FOR MAKING FLEXOGRAPHIC PRINTING PLATE, AND FLEXOGRAPHIC PRINTING PLATE

摘要

Objects of the present invention are to provide a process for producing a flexographic printing plate precursor for laser engraving that has excellent rinsing properties for engraving residue and can give a plate having excellent printing durability, to provide a flexographic printing plate precursor obtained by the process, and to provide a flexographic printing plate and a process for making the flexographic printing plate. Disclosed is a process for producing a flexographic printing plate precursor for laser engraving, comprising steps of: forming a relief-forming layer formed of a resin composition for laser engraving; and crosslinking the relief-forming layer by means of heat and/or light to thus obtain a flexographic printing plate precursor having a crosslinked relief-forming layer, wherein the resin composition for laser engraving comprises (Component A) an N-vinyl compound, (Component B) a polymerizable compound, (Component C) an ethylenically unsaturated bond-containing binder polymer, and (Component D) a polymerization initiator.
