The present invention is directed to polyurethane compositions containing triazine or both triazine and oxazoline or imino carbamate groups which are prepared by reacting: 1. (a) at least one alkoxylated hydroxy aromatic oligomer containing at least one triazine group, or (b) at least one alkoxylated hydroxy aromatic oligomer containing at least one triazine group and at least one oxazoline group, or (c) at least one alkoxylated hydroxy aromatic oligomer containing at least one triazine group and at least one imino carbamate group, or (d) at least one alkoxylated hydroxy aromatic oligomer containing at least one triazine group and at least one other N-heterocyclic group, or (e) a mixture of the above and 2. at least one material having more than one isocyanate group per molecule wherein the components are employed in proportions which provide a ratio of isocyanate groups to hydroxy groups of from about 0.05:1.0 to about 10.0:1.0, preferably from about 0.95:1.0 to about 1.5:1.0.
