Antistatic highly adhesive film, process for producing said film, and magnetic card using said film

An antistatic highly adhesive film having high adhesivity to an ultraviolet curing resin layer and a magnetic layer, and comprising a polyester film and an antistatic highly adhesive layer provided on at least one side of the polyester film, said adhesive layer comprising a copolymer (A) and a polymer (B) at a weight ratio of 95:5 to 50:50, the copolymer (A) having a second order transition temperature (Tg) of 10.degree.-80.degree. C. and being obtained by copolymerizing
