Abstract

A process for producing a biaxially oriented adhesive polyester film comprising the steps of: (1) forming a thin film of an aqueous dispersion by applying onto both surfaces of an unoriented or monoaxially oriented base film of an aromatic polyester containing 5 to 20% by weight of a white pigment, the aqueous dispersion containing 5 to 70% by weight of fine particles having an average particle diameter of 5-80 nm of an aromatic copolyester having a secondary transition point of 50 to 120 DEG C, 5 to 70% by weight of find particles having an average particle diameter of 5-120 nm of an acrylic copolymer having a secondary transition point of 50 to 120 DEG C, and 3 to 50% by weight of a water-soluble organic sulfonic acid salt; and, (2) while or after the thin film of the aqueous dispersion is dried, stretching the film biaxially or monoaxially to form a biaxially oriented film having an adhesive coating film.
