Abstract
An adhesive masking article for shielding a protected work surface from a coating applied to a surface adjacent the protected work surface includes a backing layer having first and second opposed major surfaces, and at least one edge, an adhesive on at least a portion of at least one of the first and second backing layer opposed major surfaces, and a barrier inducing treatment on at least an edge surface of the masking article to contact the coating when the coating contacts the edge of the backing layer, thereby causing a barrier to form along the edge of the masking article that impedes the migration of the coating past the edge of the masking article beneath the masking article.
