ABSTRACT:
Novel stable substantially linear unsaturated polyurethane resins which lend themselves to polymerization, in air, by actinic light using low levels of photo-initiator and with no amine activator, said resins having a tertiary amine group and a terminal vinylidene group, i.e. H.sub.2 C .dbd. C< by the reaction of an isocyanate with a hydroxyalkyl acrylate or an allyl alcohol monomer. Both the resin and the cured products therefrom have little or no detectable amine odor.
