Abstract

PURPOSE: To obtain a urea-melamine resin usable for manufacturing decorative laminates, having a good storage stability for a long time, by conducting the methylolation and copolycondenstation under alkaline conditions, and by formation of methylene linkages and alkoxylation together with copolycondensation under acidic conditions.
