Abstract
A bridging agent for improving the bond between incompatible component layers of laminates comprising one or more N-substituted melamine compounds. The bridging agent is comprised of an N-substituted melamine, an N-substituted melamine formaldehyde resin, a hybrid N-substituted melamine resin, or mixtures of these resins. The bridging agent improves bonding between laminate layers known not to bond well together such as between a styrenated polyester top coat and a melamine impregnating resin. As a result of improving the bond between the incompatible component layers, the bridging agent improves the blister resistance and cove forming characteristics of the laminate. The bridging agent can be used to improve bonding both with and without an overlay paper layer.
