Abstract
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.
