ABSTRACT:
The present invention relates to an adhesive containing a primary water soluble adhesive agent, an adhesion promoter for providing initial tack to composition, and a water soluble polymer comprising an imine compound in an amount sufficient to provide adhesion to polymeric films and preferential anchorage of such films to a substrate. The primary adhesive agent is generally present in the amount of about 2 to 60% by weight, the adhesion promoter is generally present in an amount of about 5 to 30% by weight and the imine compound is generally present in the amount of about 0.1 to 7% by weight of the adhesive, with the balance being water. The adhesive include one or more of the following optional components: a primary chelating agent in an amount of about 0.5 to 6% by weight, a thinning agent in an amount of up to about 1% by weight, or a secondary chelating agent, a wetting agent, or a humectant, each in an amount of up to about 3% by weight of the adhesive. Also, the invention relates to a method of making the adhesive, the adhesive produced by the method and articles such as package sealing tapes having a substrate such as a plastic film with one of the adhesives described above provided on at least a portion and preferably substantially all of one surface of the plastic film.
