Zusammenfassung:The invention concerns the production of oriented polymeric films in which a layer of a heat curable silicone resin composition is formed on a layer of a polymeric film which is thereafter stretched at an elevated temperature to effect orientation of the film. The heat curable silicone resin composition includes a volatile inhibitor for inhibiting curing of the composition while stretching is effected. Suitabe inhibitors include volatile amines, alkynes and acetylene alcohols. Films so produced can be used as release films.
