RELIEF PRINTING PLATE PRECURSOR FOR LASER ENGRAVING AND PROCESS FOR PRODUCING SAME, AND RELIEF PRINTING PLATE AND PROCESS FOR MAKING SAME

摘要

An object of the present invention is to provide a relief printing plate precursor for laser engraving that is excellent in rinsing properties for engraving residue and engraving sensitivity and can give a sharp engraved shape.;Disclosed is a relief printing plate precursor for laser engraving comprising a relief-forming layer formed of a resin composition for laser engraving, or a crosslinked relief-forming layer obtained by crosslinking the relief-forming layer formed of the resin composition for laser engraving, wherein the resin composition for laser engraving comprises a binder polymer as Component A, and carbon black of which pH is higher than 6 and an average particle size when being dispersed into water is equal to or less than 500 nm as Component B.
