Abstract
Improved adhesion to a polyolefin, especially polypropylene, of substrates of acrylic-based or other protective polymers, in the form of a plastic film, sheet, or coating or a latex or solvent-based paint, ink, or coating is achieved by use of an intermediate layer, laminate, or veneer of a blend of segmented copolymer of a polyolefin and a poly(methacrylate) which is blended with a core/shell copolymer having a crosslinked rubber core.
