Abstract
An adhesive based on glues, resins, and an alcohol is provided. The adhesive develops strengths similar to synthetic resin dispersions in the bonding of paper to plastic surfaces and has a high wet adhesive strength. The adhesive is particularly useful in the labelling of plastic surfaces particularly plastics such as polystyrene, polycarbonate, polyvinyl chloride, and polyethylene terephthalate.
