ABSTRACT:
A method is provided for forming a tacky surface area on a styrenic resin, such as a polystyrene label. A thin film is applied of an alkyl, aryl or alkaryl ester of a phosphorus oxyacid providing a tacky area suitable for bonding to another surface. A composition particularly useful for bonding polystyrene labels to bottles is a solid alkyl, aryl or alkaryl ester of a phosphorus oxyacid and a cosolvent selected from terpenoids and aromatic compounds having a flash point of at least 35.degree. C. and a boiling point between 100.degree. C. and 260.degree. C.
