Resin composition for laser engraving, method for producing relief printing plate precursor for laser engraving, relief printing plate precursor, plate making method for relief printing plate, and relief printing plate

摘要

The object of the present invention is to provide a relief printing plate precursor for laser engraving that has high ink resistance to both water-based ink and solvent ink, and is excellent in engraving sensitivity, a method for producing the same, and such a printing plate precursor. It is to provide a resin composition for laser engraving that is suitably used. The resin composition for laser engraving of the present invention comprises (Component A) a cross-linkable group, a compound that is a plastomer at 20 ° C., and (Component B) a cross-linking agent. The functional group is a (meth) acryloyl group, and at least one of the component A and the component B has an ionic group.
