METHOD FOR MANUFACTURING FLEXOGRAPHIC PRINTING PLATE

摘要

The present invention provides a method for producing a flexographic printing plate which has an ability to prevent plate surface contamination and a persistency of the effect thereof and which allows a high-quality printing in a large scale. There is disclosed a method for producing a flexographic printing plate from a flexographic printing original plate provided with a photosensitive resin layer comprising a photosensitive resin composition containing at least (A) a hydrophobic polymer comprising a water-dispersible latex, (B) a photopolymerizable compound and (C) a photopolymerization initiator, wherein the method comprises a main exposure step, a development step and a post-exposure step, characterized in that a treatment solution containing a first amino-modified silicone having an amine equivalent of 1000 g/mol or less and a second amino-modified silicone having an amine equivalent of 3000 g/mol or more in a mass ratio of from 2.5:1 to 1:6 is contacted with the whole surface of the flexographic printing plate.
