Abstract
The surface of an aromatic liquid crystalline polyester film is modified to have improved adhesion by: (a) applying an adhesion-promoting coating to the film; (b) subsequently heating the film to a temperature above the melting point of the polyester; and, (c) applying pressure to the heated film. Preferably, the film is placed between two portions of a release film (e.g. a polyimide) prior to applying pressure.
