Patent ID: 7695816

Claim:
A composite article comprising: a first layer comprising a polymer resulting from the reaction of at least one ethylenically unsaturated monomer; a second layer different than said first layer and comprising a polyurethane resulting from the reaction of a isocyanate-reactive resin and a polyisocyanate; and an adhesion promoter comprising a first reactive end group selected from the group of ethylenically unsaturated monomers, ethylenically unsaturated acrylate monomers, ethylenically unsaturated methacrylate monomers, and combinations thereof and a second reactive end group that is reactive with isocyanate, and wherein said adhesion promoter is dispersed in at least one of said first layer and said second layer and reacted into said first and second layers through differentially reactive groups such that said adhesion promoter is compatible with said first and second layers to improve adhesion therebetween.
