Abstract:
A plasticized polyvinylchloride substrate coated with a pressure-sensitive adhesive polymer (PSA) comprising about 50 to about 99.8% C.sub.1 -C.sub.12 alkyl acrylate monomer, 0 to about 40% vinyl unsaturated monomer, 0.1 to about 10% carboxylic acid functionalized monomer, 0 to about 10% hydroxyl functionalized monomer and about 0.1 to about 10% cyclic ether monomer selected from allyl glycidyl ether, glycidyl methacrylate and mixtures thereof, wherein the PSA has a T.sub.g of less than -10.degree. C. and greater than about -45.degree. C. and wherein said substrate has a value of Peel Adhesion After Heat Aging which is at least 40% of the value of PSA 180% Angle Dynamic Peel determined before heat aging and a value of Shear Strength After Heat Aging which is at least 50% of the value of Shear Strength determined before heat aging.
