A membrane formed by coating an aqueous coating liquid comprising an antistatic agent or anticlouding agent on one or both surfaces of an aliphatic polyester film comprising a specific amount of a lubricant or an antiblocking agent, can remarkably improve adhesion of the membrane (antistatic layer or anticlouding layer) to the aliphatic polyester film, and thus the effect of the membrane (antistatic effect or anticlouding effect) can be continuously exhibited for a long period.
在含有一定量润滑剂或抗阻剂的脂肪族聚酯薄膜的一个或两个表面上涂布含有
抗静电剂或抗混浊剂的
水性涂布液而形成的膜,可以显著提高膜(抗静电层或抗混浊层)与脂肪族聚酯薄膜的附着力,因此膜的效果(抗静电效果或抗混浊效果)可以长期持续地表现出来。
