Abstract: Aqueous adhesive preparations, more particularly for labeling bottles, were to be formulated in such a way that high adhesion and the absence of odors during delabeling would be guaranteed. This was achieved by using aqueous preparations containing 1 to 70% by weight of a copolymer of monomers containing acid groups and hydrophobic monomers and, if desired, one or more auxiliaries for improving wet adhesive strength and/or for controlling open time and, if desired, preservatives, defoamers, dyes and/or other typical auxiliaries as labeling adhesives for bonding water-permeable hydrophilic substrates to hard surfaces.

Abstract: A hydrophilic, high molecular weight nonionic polyurethane, characterized by solubility in water and by a specific viscosity of at least 0.4 (1% by weight solution at 20° C.) is provided. Examples of such polyurethanes are those characterized by the following structural units: a) —O(—CH2—CH2—O)n—, where n=8 to 500, and b) —CO—NH—X—NH—CO—, where X is an aliphatic or cycloaliphatic radical. Also provided are methods of using the polyurethane as an adhesive, more particularly a hotmelt adhesive or a solvent-based adhesive, for example a wallpaper adhesive and labelling adhesive, of using polyurethane as a stabilizer in the emulsion polymerization of, in particular, vinyl acetate and vinyl chloride and in the copolymerization of ethylene and vinyl acetate, and of using the polyurethane as a thickener for aqueous systems, more particularly together with nonionic surfactants.

Abstract: The invention relates to an adhesive system for labeling containers, more especially hollow containers, with wrap-around labels. The adhesive system comprises a pick-up adhesive and an overlap adhesive. It is characterized in that, in the wet state, the pick-up adhesive has sufficient wet bond strength for labeling and, in the dried state, does not adhere to at least one of the substrates. The pickup adhesive contains 5 to 85% by weight and preferably 5 to 60% by weight of at least one water-soluble polymer based on casein, starch, dextrin, glucose, polyvinyl alcohol, polyurethane or polyacrylic acid, 0.00 to 1.00% by weight and preferably 0.01 to 0.30% by weight of at least one defoamer, 0.00 to 1.00% by weight and preferably 0.01 to 0.30% by weight of at least one preservative and water as the balance to 100% by weight.

Abstract: 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.
