A process for making an essentially dry biomedical electrode comprising of an electrode plate having a first surface and a second surface, means for electrically connecting said electrode plate to a lead wire of an electro-medical device, and a swellable, dermally-nonirritating, conformable, cohesive, ionic, hydrophilic polymeric conductive material on said second surface of said electrode plate for enhancing electrical connection with the skin, said process comprising: forming said conductive material on said electrode plate by the steps of: (a) compounding a precursor of said conductive material comprising (1) a water soluble polyhydric alcohol which is a liquid at about 20°C.; (2) an ionic, unsaturated, free radically polymerizable material soluble in said polyhydric alcohol; (3) a photo initiator; and (4) a crosslinking agent of a multi-functional unsaturated free radically-polymerizable material; (b) coating said precursor on said second surface of said electrode plate or onto a releasable transfer sheet; and (c) polymerizing said coated precursor by exposure to ultraviolet light whereby an electrically conductive pressure-sensitive adhesive layer is formed on said electrode plate or said transfer sheet; and (d) if formed on said transfer sheet, adhering said adhesive layer to said second surface of said electrode plate.
