Abstract
Modified melamine-formaldehyde resins prepared by reacting melamine with formaldehyde at a F:M molar ratio in the range of about 1.55:1-2.5:1 under alkaline conditions, wherein the resin is prepared in the presence of about 1-10 wt % dicyandiamide and about 1-10 wt % sorbitol based on the total weight of resin solids. The resins are used to impregnate substrates in the preparation of decorative laminates. The laminates can be used to produce, for example, furniture, countertops or flooring.
