Abstract

PURPOSE: A laminate having improved adhesiveness to a surface material, e.g., a magnetic material, without using an undercoat, obtained by laminating a polyethylene terephthalate film containing a specific amount of a polyethylene glycol having a high molecular weight on a base film.
CONSTITUTION: B) A film layer of a polyester consisting of not less than 80 wt.% of polyethylene terephthalate and 0.5W10 wt.% of a polyethylene glycol having a molecular weight of 5,000W200,000 is laminated on A) a base film layer of a polyester containing not less than 80 wt.% of polyethylene terephthalate. The laminated film is then stretched to be biaxially oriented, preferably heat-treated at a temperature from 2200 to lower than its melting point. A contact angle between the surface of the film layer B and water is preferably 25W55 degrees.
EFFECT: Having uniform coating performance, antistatic properties, and transparency, without requiring surface treatment.
