<p>A water soluble, hot-melt processable, wet-stick pressure sensitive adhesive comprises polyethyloxazoline and a plasticizer therefor, for instance N,N min -bis(2-hydroxyethyl)-dimethylhydantoin. Optionally an antioxidant is present and small amounts of rubbers and tackifiers may also be added. The adhesive is particularly useful for high speed labeling of cold and/or wet substrates, and labels applied to such substrates are readily removable, subsequently, with the aid of a polar solvent such as water.</p> |
