US 5,962,546 A · Cationically polymerizable compositions capable of being coated by electrostatic assistance

Abstract

Compositions containing conductivity enhancers, which are capable of being coated onto a substrate by means of electrostatic assistance. The compositions comprise one or more cationically polymerizable monomer(s), one or more cationic initiator(s), and one or more non-volatile conductivity enhancer(s) having anionic and cationic portions which are soluble in the monomer(s) and which do not interfere with cationic polymerization wherein the anionic portion is a non-coordinating carbon-containing anion. The compositions may further comprise one or more dissociation enhancing agent(s), oligomer(s) or polymer(s), preferably co-reactive, free-radically curable monomer(s), free-radical generating initiator(s), leveling agents, and other additives or adjuvants to impart specific properties to the polymerized composition.

Dependent claims

A cationically polymerizable composition suitable for application to a substrate by means of electrostatic assistance and comprising:

a) one or more cationically polymerizable monomer(s);
b) one or more cationic initiator(s);
and
c) one or more non-volatile conductivity enhancer(s) having cationic and anionic portions, which are soluble in said monomer(s) and which do not interfere with polymerization, wherein the anionic portion is a non-coordinating organophilic carbon-containing anions, and wherein said conductivity enhancer(s) is a chemically different component than said initiator(s);
said composition having a conductivity sufficient to be applied to a substrate by means of electrostatic assistance and said monomer(s) and initiator(s) being such that when in combination they have a conductivity insufficient to be applied to a substrate by means of electrostatic assistance.
