Abstract: PURPOSE:To provide the titled protective film which is releasable even after long- term storage and does not damage the fabrication properties of a coated metal, by a method wherein a polyester-ether, a polyester, a polyolefin and a polycarbonate are blended together in a specified ratio. CONSTITUTION:(A) 10-70wt% of a polyester-ether having a m.p. of 90- 170 deg.C (e.g. a polytetramethylene terephthalate-isophthalate-polyoxytetramethylene glycol copolymer), (B) 10-70wt% of a polyester in which not less than 40mol% of the dicarboxylic acid component is terephthalic acid (e.g. a polyethlene terephthalate), (C) 1-30wt% of a polyolefin (e.g. a polyolefin or an ionomer), and (D) 0- 50wt% of a polycarbonate (pref. a polycarbonate resulting from the reaction of bisphenol A with phosgene) are blended together.
