PURPOSE:To improve the adhesiveness to a metal and chemical resistance, by forming an adhesive layer composed of a composition prepared by compounding a specific amount of a specific polyfunctional epoxy compound with a specific amount of a polyamide resin on a polyester film. CONSTITUTION:A composition containing 10-65wt.% of a polyfunctional epoxy compound having at least two epoxy groups in one molecule thereof and 90-35wt.% of a polyamide resin having a m.p. of 160 deg.C or less or a resin based on the reaction product of both components is dissolved in a solvent to prepare a coating solution. This solution is applied to a polyester film and dried to obtain a polyester film laminate having an adhesive layer of a thickness of 3-100mum. the absolute value of the dimensional change ratio of the obtained polyester film laminate due to 150 deg.C/30min treatment is 0.4% or less. |
