A METHOD FOR PRODUCTION OF FLEXOGRAPHIC PRINTING PLATE PRECURSORS FOR LASER ENGRAVING

摘要

In order to provide method for stably producing a flexographic plate original for laser engraving, this method for producing a flexographic plate original for laser engraving contains, in the given order, at least: (1) a step for individually preparing at least two fluids having reactivity with each other; (2) a step for forming a reactive resin composition by inline mixing of the at least two fluids; (3) a step for forming a casting film by casting the reactive resin composition on a mold release body; (4) a step for heating the casting film; and (5) a step for forming an independent sheet comprising the reactive resin composition by peeling the casting film from the mold release body.
