Abstract
Abstract A thermoplastic resin film laminate which comprises a thermoplastic resin film, particularly, a polyester film and a layer of a polyester resin composition provided on at least one surface of the film, said composition comprising (A) a water insoluble polyester copolymer composed of a mixed dicarboxylic acid component containing a dicarboxylic acid having metal sulfonate group in an amount of 0.5 to 15 mol % based on all the dicarboxylic acid component and a glycol component; and (B) inert particles; the weight ratio of (A)/(B)= 100 , 0 0 0 /0.5-3,0 0 0. Optionally, the composition can contain one or more ingredients selected from the group consisting of a water soluble silicone, a polyfunctional reactive compound, a polyethylene glycol and its derivative and an antistatic agent. The thermoplastic resin film laminate is preferably produced by so-called in-line coating.
