Abstract
PURPOSE: To enhance adhesion of a polyester film to a radical-curable resin, by providing an adhesive layer containing a specified linear copolymerized polyester and a radical-curable resin, to the surface of a polyester film.
CONSTITUTION: One side or both sides of a polyester film are provided with an adhesive layer comprising (A)30W97wt% of a linear copolymerized polyester of softening pt. ≤200°C, composed of a dibasic acid residue containing 40% or more terephthalic acid, or terephthalic and isophthalic acids, and a glycol residue, and (B)70W30wt% of a radical-curable resin. Said glycol residue of the polyester (A) is preferably composed of 20W70mol%, based on the total glycol, of an ethylene glycol residue and/or 1.4-butanediol residue, and the balance of other glycol residues.
