Polyesterfolie mit knötchenförmiger Oberfläche

摘要

A polyester film having a nodule surface is disclosed. The acrylic coating is preferably a crosslinked composition having a relatively high methyl methacrylate content and specific surfactants. The acrylic coating composition is applied as an aqueous dispersion to polyester film, preferably after corona treatment of the polyester film. The nodule surface reduces the coefficient of friction of the polyester film. The coating composition comprises from 60 to 90 mole percent methylmethacrylate; from 10 to 35 mole percent of at least one modifier selected from the group of ethylacrylate, propylacrylate, butylacrylate, and mixtures of these; and from 3 to 10 mole percent of a crosslinkable monomer or a self-crosslinking monomer selected from the group of N-methylolmethacrylamide, N-methylolacrylamide, acrylamide, methacrylamide, and mixtures of these; with from 2 to 15 weight percent of the nonionic surfactant and at least 0.1 percent by weight of the anionic surfactant.
