More Information
Summary:PURPOSE:To obtain excellent blocking resistance and solvent resistance by laminating coating agent made of at least two types or more of aromatic, aliphatic dicarboxylic acid, ester formable metal salt sulfonate compound as acid ingredients, and aliphatic glycol or alicyclic glycol, diethylene glycol as glycol ingredient. CONSTITUTION:Aqueous soluble copolymer polyester to be laminated at least on one side surface of a polyester film contains two or more types of 70mol% or more of aromatic dicarboxylic acid, 0.01-8mol% of aliphatic dicarboxylic acid and 8-25mol% of ester formable alkali metal salt sulfonate compound as acid ingredients. It contains 80-99mol% of 2-8C aliphatic glycol or 6-16C alicyclic glycol, and 1-20mol% of diethylene glycol as glycol ingredients. Melted and extruded polyester film is longitudinally oriented, a coated surface is corona discharge treated, coated with aqueous solution of aqueous soluble copolymer polyester, dried, laterally oriented, crystalline-oriented, and an easily adhesive layer is laminated.
