A flame-retardant film comprises a polymeric substrate having a receptive layer to which is bonded a retardant layer comprising a flame-retardant agent consisting essentially of a halogenated epoxy resin. A modifying layer, such as a slip coat or an adhesive barrier layer, is preferably applied to the retardant layer. The film exhibits improved adhesion to inks and photo-curable varnishes and is of utility in the electrical field. |
