Title:

The manufacturing method of the flexographic printing original edition for laser sculpture, the platemaking method of a flexographic printing, and the resin composition for laser sculpture

Document Type and Number:

Japanese Patent JP6144350

Kind Code:

B2

Abstract:

Provided are a resin composition for laser engraving having excellent roll detachability and sheet appearance when the resin composition is subjected to calender processing, and a method for producing a flexographic printing plate precursor for laser engraving and a method for producing a flexographic printing plate, which use the resin composition for laser engraving. Disclosed is a method for producing a flexographic printing plate precursor for laser engraving, the method including, in the following order, a layer forming step of forming a relief forming layer using a resin composition for laser engraving, through sheet molding using a calender roll; and a crosslinking step of crosslinking the relief forming layer by means of heat, and obtaining a flexographic printing plate precursor for laser engraving having a crosslinked relief forming layer, in which the resin composition for laser engraving is a resin composition including a diene-based polymer, a thermal polymerization initiator, carbon black, and a filler other than carbon black.
