Abstract
The invention provides a method of making a film comprising the steps of: (A) providing a film comprising a layer of thermoplastic polymer having dispersed therein a fluorochemical hydrophilicity imparting compound according to the formula: Rf—Q—Z—X—T, wherein Rf represents a partially or fully fluorinated aliphatic group having at least 3 carbon atoms, Q is a linking group or a covalent bond, Z is a poly(oxyalkylene) group, X is an oxygen atom or NR wherein R is a hydrogen atom or an alkyl or aryl group, and T is a hydrogen atom or an organic group having no more than 6 carbon atoms; (B) applying a coating comprising at least one non-volatile component on said film; and (C) when said coating contains volatile components, drying said coating to remove said volatile components from said coating. Further provided are single- and multi-layer films.
