13 . (canceled)
14 . (canceled)
15 . The composite article of claim 1 , consisting of the backing and dampening layers.
16 . The composite article of claim 1 , wherein the composite article comprises a release layer disposed between the backing and dampening layers, optionally wherein the composite article consists of the release, backing, and dampening layers.
17 . A method of forming the composite article as set forth in claim 1 , said method comprising the steps of:
providing the backing layer;
providing the composition; and
applying the composition to at least a portion of the backing layer to form the composite article.
18 . The method of claim 17 , wherein the composition comprises a solvent, the method further comprising the step of heating the composition after application to the backing layer to dry the composition.
19 . A method of disposing a dampening layer on a fastener, said method comprising the steps of:
providing the fastener comprising a threaded surface;
providing a composite article, wherein the composite article is as set forth in claim 1 ; and
disposing the dampening layer on at least a portion of the threaded surface;
wherein the dampening layer is adapted to provide the fastener with improved loosening-resistance as compared to a fastener free of the dampening layer.
20 . A method of joining a fastener and an element together, said method comprising the steps of:
providing the fastener comprising a threaded surface;
providing the element;
providing a composite article, wherein the composite article is as set forth in claim 1 ;
