ABSTRACT:
Layers of adhesives which are applied onto polyolefin surfaces from aqueous dispersion exhibit improved adhesion if a dicarboxylic acid dihydrazide of 2 to 10 carbon atoms and an aqueous dispersion of an adhesive polymer are applied, preferably as a mixture, onto the polyolefin surfaces which have been pretreated by corona discharge.
