Resin composition for laser engraving, 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

A resin composition for laser engraving that comprises (Component A) a resin that is a plastomer at 20°C, (Component B) a polymerizable compound, and (Component C) a polymerization initiator, wherein Component A has a constitutional repeating unit having an acid group, and the content of the constitutional repeating unit having an acid group is 0.01 to 15 mass% relative to a total mass of Component A. A flexographic printing plate precursor that has a relief-forming layer formed of the resin composition for laser engraving on a support, and a flexographic printing plate precursor that has a crosslinked relief-forming layer obtained by crosslinking a relief-forming layer formed of the resin composition for laser engraving by heat and/or light.
