Abstract

A multilayer substrate for application to a substrate. The multilayer substrate includes a film layer having first and second surfaces, a fibrous material layer having first and second surfaces, and a discontinuous adhesive region layer situated between the film layer and the fibrous material layer. The discontinuous adhesive region layer adheres the second surface of the film layer to the first surface of the fibrous material layer.
