Abstract: Articles coated with a thermoset reaction product of a liquid resin composition comprising a reactive polymer and an N,N'-bis(alkoxymethyl)uron such as N,N'-bis(butoxymethyl)uron. The reactive polymer contains reactive groups such as hydroxyl and carboxyl and is of molecular weight in the range 300 to 5000. The uron ether is employed as a cosolvent for the polymer whereby the solution may be applied as a coating without the need for significant amounts of conventional solvents. Interaction between the polymer and the uron ether promoted by heat in the presence of acid catalyst shifts the role of the uron ether to that of a crosslinking agent for the polymer.
