The resin composition for laser engraving, flexographic printing plate precursor and method of manufacturing the same for laser engraving, as well as, flexographic printing plate and a process for making same

摘要

PROBLEM TO BE SOLVED: To provide a laser engraving resin composition by which a flexographic printing plate having superior durability in both of an aqueous ink and a solvent ink can be obtained, a flexographic printing plate form using the laser engraving resin composition and its manufacturing method, a platemaking method of the flexographic printing plate using the manufacturing method, and the flexographic printing plate obtained by the platemaking method.;SOLUTION: A laser engraving resin composition is characterized by containing (component A): a polymer initiator having a chain polymerization initiator residue group having a connecting part obtained by sequential polymerization and a specified structure, and (component B): a polymerizable compound. There are also provided a flexographic printing plate form using the laser engraving resin composition and its manufacturing method, a platemaking method of the flexographic printing plate using the manufacturing method, and the flexographic printing plate obtained by the platemaking method.;COPYRIGHT: (C)2014,JPO&INPIT
