Abstract
Abstract A polymeric paint applique is transferred from a substrate to the sidewall of a tire during the curing process. Upon curing, the bond between the tire and the applique is significantly greater than that between the substrate and the applique. The substrate may remain intact with the applique bonded to the tire sidewall until the tire is put into use, serving as a protective layer for the applique.
