Photocurable interpenetrating polymer networks

Abstract

A resin composition comprising an interpenetrating polymer network comprising: (a) 5 to 95 weight percent of a polyurethane prepolymer; (b) 5 to 95 weight percent of a waterborne polymer component; and (c) optionally, a chain extender or crosslinker; wherein either the polyurethane prepolymer has at least one functional group that is photopolymerizable or the waterborne polymer component has at least one functional group that is photopolymerizable; or wherein both the polyurethane prepolymer and waterborne polymer component have at least one functional group that is photopolymerizable.
