Abstract
A self-supporting sheet-like structure comprises a coating, which reduces sliding friction, on at least one surface of the substrate. The slip-improving coating is produced by treating this substrate surface by means of an electric corona discharge between a high voltage electrode and a grounded counter-electrode while simultaneously spraying an aerosol into the corona discharge zone. The aerosol contains a film-forming agent as a slip agent, for example aqueous solutions or emulsions of monoesters of glycerol and long-chain fatty acids.
