Abstract
The invention concerns an electrically conductive, transparent, pressure-sensitive adhesive film with an electric conductivity above 10.sup.-5 S, for the production of biomedical electrodes, consisting of PA1 100 parts by weight of a carboxyl group-containing copolymer on an acrylate basis; PA1 50 to 150 parts by weight of a water-soluble amine; PA1 50 to 250 parts by weight of a polyoxyalkylene with a molecular mass of below 1000 and/or a polyalcohol and/or its derivatives; PA1 50 to 200 parts by weight of a solution of electrolytes and PA1 0.1 to 6 parts by weight of a cross-linking agent.
