Patent number: 8258233Abstract: The invention provides an adhesive with an aqueous polymer dispersion. The aqueous polymer dispersion comprises a copolymer of a) esters of vinyl alcohol with C2 to C6 monocarboxylic acids, b) ?,?-unsaturated C3 to C9 carboxylic acids or vinyl-substituted phosphonic or sulfonic acids, c) polyunsaturated monomers, and optionally d) non-polar, copolymerizable monomers and e) copolymerizable monomers that carry polar functional groups, where the ratio of c:b ranges from 1:10 to 1:400. The adhesive has high adhesion strength, stable viscosity during high-speed automatic application process and, is optionally, remoistenable with water or becomes water-soluble. The adhesive may be advantageous used as wood adhesive, remoistenable adhesive, label adhesive, bottle adhesive, and the like.Type: GrantFiled: April 5, 2010Date of Patent: September 4, 2012Assignee: Henkel AG & Co.

Patent number: 5985074Abstract: The invention is an adhesive system for applying wrap around labels to containers. The system comprises a hotmelt pick-up adhesive which is active at the temperature which the label is applied and loses its bonding ability after the adhesive sets and an overlap adhesive for bonding the label overlap. At its application temperature, the pick-up adhesive has significantly higher adhesiveness, measured at its application temperature than at its conventional storage temperature. In addition, the adhesive preferably has a greater affinity for the label than for the container bearing the label. Consequently, the label can be easily removed from the hollow body without leaving residues of adhesive. If, nevertheless, a residual adhesive should remain on the hollow body, it can be dissolved by an alkaline solution.Type: GrantFiled: December 22, 1997Date of Patent: November 16, 1999Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Marcus Heemann, Eckhard Puerkner, Wolfgang Klingberg, Bernhard Herlfterkamp, Hermann Onusseit, Ralf Gossen
