Patent ID: 8652760

Claim:
A method for producing a printing plate, comprising providing a printing plate precursor for laser engraving comprising a relief forming layer comprising a cured resin material formed by thermally crosslinking a resin composition comprising at least (A) non-porous inorganic particles, (B) a binder polymer having a glass transition temperature (Tg) of 20° C. or higher, and (C) a crosslinking agent, wherein the (B) binder polymer having a glass transition temperature (Tg) of 20° C. or higher is at least one polymer selected from the group consisting of an epoxy resin, a polyvinyl acetal and a polyester; and wherein the (C) crosslinking agent is selected from the group consisting of a silane coupling agent that includes two or more silane coupling groups linked via a linking group containing a heteroatom, a compound having at least two isocyanate groups in the molecule, and a compound having two or more dibasic acid anhydride sites in the molecule; and laser engraving the relief forming layer in the printing plate precursor for laser engraving.
