ABSTRACT:
The invention is directed to a conductive composition for iontophoretic electrodes comprising, based on solids: (a) 20-90% wt finely divided particles of silver, carbon, graphite and mixtures thereof; (b) 0-75% wt. finely divided particles of silver chloride; (c) 0.25-10% wt. hydrophilic polymer; and (d) 2-15% wt. hydrophobic thermoplastic polymer having a glass transition temperature (Tg) >40.degree. C. The invention is also directed to compositions wherein the binder comprises 5-15% wt. copolymer of hydrophilic and hydrophobic monomers.
