  • Patent number: 6238509
    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.

  • Patent number: 5672199
    Abstract: A composition useful as an antislip for articles with plastic surfaces is provided. Said composition typically comprises from 35 to 45% by weight of a rosin or derivative thereof, preferably a water-soluble, saponified rosin, from 5 to 10% by weight of an alcohol, preferably selected from the group consisting of ethane-1,2-diol, propane-1,2-diol and propane-1,2,3-triol, from 5 to 10% by weight of a liquefying agent, preferably selected from the group consisting of alkali metal alkyl benzenesulfonates containing up to 8 carbon atoms in the alkyl chain and alkaline earth metal alkyl benzenesulfonate containing up to 8 carbon atoms in the alkyl chain, optionally from 15 to 25% by weight of a propellant, e.g. dimethyl ether, optionally from 0.5 to 5% by weight of a water-soluble polymer selected from the group consisting of one or more of the following substances: starch, starch derivatives, dextrin, polyurethane, and cellulose ethers, and the balance water.
