POLYESTER FILM FOR FLEXOGRAPHIC PRINTING PLATE

摘要

A polyester film for a flexographic printing plate is provided to increase contact power with a base layer by using polyester resin and adhesive power with photosensitive resin by using acryl resin and to secure good antistatic property by forming an antistatic layer by a quaternary ammonium antistatic agent. A polyester film for a flexographic printing plate is composed of: a polyester base layer(B); an adhesive layer(A) formed on one surface of the polyester base layer by using coating solution produced by mixing acryl resin and polyester resin; and an antistatic layer(C) formed on the opposite surface of the polyester base layer. The coating solution forming the adhesive layer is produced by dissolving polyester resin of 100wt.%, acryl resin of 30~200wt.%, a crosslinking agent of 5~50wt.%, and a surfactant of 1.0~3.0wt.% in the refining water.
