ABSTRACT:
This invention is directed to a novel water soluble conductive material which is capable of being polymerized by actinic radiation. More specifically, this invention involves the use of a radiation curable quaternary ammonium salt obtained by mixing at least one tertiary amine having acryloyl or methacryloyl unsaturation and at least one halide. When the water-soluble conductive material is subjected to actinic radiation sufficient to cause polymerization, it maintains its conductive character, but becomes essentially impervious to attack by water or solvent, and remains tack-free even at high relative humidity. When the water-soluble conductive material is polymerized by actinic radiation, it is not necessary to drive water off during cure and then rehumidify to obtain proper conductivity as is often necessary with the prior art coatings.
