The present invention relates to a composite material including a substrate with a first and a second surface, a boundary layer which is comprised of one or more compositions, and a topical application. The boundary layer is applied on the first surface of the substrate, and the topical application is applied to a surface of the boundary layer opposite of the substrate. Transfer efficiency of the topical application is enhanced as the transfer forces necessary to separate the topical application from the boundary layer are lower than the transfer forces necessary to separate the substrate from the boundary layer.
