Low pressure melamine resin laminates

Claim 1

A heat and pressure consolidated article comprising A. a self-supporting substrate and B. a decorative, cellulosic paper sheet having a basis weight of at least about 40 pounds per 3,000 square foot ream, containing at least about 60% α-cellulose and being impregnated with a composition of matter comprising a mixture of 1. an aqueous melamine/formaldehyde resin solution wherein the melamine to formaldehyde ratio thereof ranges from about 1:1.6 to about 1:2.5, 2. from about 2.5% to about 30.0%, by weight, based on the weight of the resin solids of (1), of an elastomer comprising a. an ethylene/vinyl chloride copolymer containing a comonomer supplying from about 0.5% to about 7.0%, by weight, based on the total weight of (a), of amide groups, b. a polyurethane resin containing from about 3.0% to about 10.0%, by weight, based on the total weight of (b), of carboxyl groups, or c. a butadiene/acrylonitrile polymer containing from about 1% to about 10%, by weight, based on the total weight of (c), of carboxyl groups, said elastomer having a particle size of up to about 20,000 Angstroms, and 3. from about 0.25 to about 1.25%, by weight, based on the total weight of solids in said composition, of an alkylene polyamine having the formula H.sub.2 N--CH.sub.2 CH.sub.2 NH].sub.n CH.sub.2 CH.sub.2 NH.sub.2 wherein n is a whole, positive integer of 0-3, inclusive.
