BIAXIALLY-ORIENTED POLYESTER ADHESIVE FILM WITH WATER SOLUBLE ACRYLIC COPOLYMER RESIN FOR IMPROVING SURFACE LEVELING PROPERTY

摘要

PURPOSE: A biaxially-oriented polyester adhesive film is provided to ensure not only enough adhesive property to a material, high optical characteristic, and winding property by improving a leveling property of a primer layer. CONSTITUTION: A biaxially-oriented polyester adhesive film with improved surface leveling property containing a water-soluble copolymerized acrylic resin comprises: a biaxially-oriented polyester base film with thickness of 50~300 micron; and a primer layer including a water-soluble copolymerization acrylic resin as a polymer adhesive layer, at one side of the base film. The thickness of the primer layer is 0.10~0.50 micron.
