In order to increase the adhesiveness of glues, colophonium resins and/or derivates thereof, as well as water-soluble mono- and polyhydric alcohols, are added thereto. When paper labels are glued with such glues on plastic materials such as polyethylene terephthalate, polycarbonate, polystyrol, polyvinyl chloride, they can only be removed by tearing. |
