Abstract
A film having a roughened surface. The film is made of an LCP and has surface recessions covering at least about 25% of the area of the surface. The film is made by pressing an embossing means against the film surface at a temperature about 15.degree.-75.degree. C. below the melting point of the polymer. The embossed film has improved resistance to abrasion.
