Abstract: A method of forming a polymer laminate which comprises mixing an unsaturated polyester resin with allyl melamine monomer; molding the mixture under heat and pressure to cause the allyl melamine to cross link the polyester chains and thereby produce a substrate; applying a melamine-formaldehyde glaze material to one face of the substrate; and heating the glazed substrate to effect polymerization and adherence of the glaze material on the substrate surface. The use of allyl melamine as the cross linking agent for the polyester prevents the glaze from cracking, blistering or peeling when subjected to heat, attack from household chemicals, or abrasion forces.
