Document Type and Number:
Japanese Patent JP3375005
Kind Code:
B2
Abstract:
PURPOSE:To enhance transparency, antistatic property and adhesive property by providing a laminated film in which surface specific resistance is specified and a contact angle with water is regulated to a specific angle on at least one side of a polyester film. CONSTITUTION:A laminated film is provided on at least one side of a polyester film such as polyethylene terephthalate, polyethylene-2, 6-naphthalate and polybutylene terephthalate. The laminated film has a surface specific resistance of <=5X10<12>OMEGA/mm<2> at 25 deg.C in relative humidity 65% and a contact angle with water is regulated to >=50 degrees. When the surface specific resistance exceeds 5 x 10<12>OMEGA/mm<2>, antrstatic effect is small and dust adheres in a printing process or the like and a possibility of causing a printing fault is increased. Thereby the transparent laminated polyester film is obtained in which antistatic property and adhesive property are compatible with each other.
