The present subject matter provides an adhesive article having a release liner that is free of silicon-containing and fluorine-containing material, and related methods of adhering a backing material of the adhesive article to a substrate. The adhesive article utilizes an amorphous polyvinyl alcohol layer that facilitates removal of a release liner from an adhesive layer. Upon removal of the release liner, the amorphous polyvinyl alcohol layer remains disposed on the adhesive layer. A method of adhering the backing material to a substrate includes dissolving the amorphous polyvinyl alcohol layer and disposing the backing material to a substrate. During dissolution of the amorphous polyvinyl alcohol layer, a weak, temporary bond is formed between the substrate and the backing material. When the amorphous polyvinyl alcohol layer substantially dissolves and dries, the adhesive layer is exposed and forms a permanent bond with the substrate.
