Abstract

PURPOSE: A specific resin layer comprising a linear polyester copolymer resin and an organic flame retarder is provided on the surface of oriented polyester films to improve the durability, resistance to solvents and blocking, flexibility and flame retardancy.
CONSTITUTION: On the surface of oriented polyester films is provided a resin layer containing a resin mixture consisting of a linear copolyester resin and a resin with hydroxyl groups on the side chains such as bisphenol-A epoxy resin in a weight ratio of 95/5-20/80, a polyfunctional isocyanate and an organic flame retarder containing halogen or halogen and phosphorus. The copolyester preferably melts at 200°C and lower and is prepared from dibasic acids more than 40 mol% of which is terephthalic aicd and glycols
