<p>PCT No. PCT/FR96/01475 Sec. 371 Date Mar. 20, 1998 Sec. 102(e) Date Mar. 20, 1998 PCT Filed Sep. 20, 1996 PCT Pub. No. WO97/11104 PCT Pub. Date Mar. 27, 1997Method of bonding a polyurethane surface to a polyvinyl chloride or other polymer substrate containing surface moisture, particularly useful for making chip cards. A resin comprising a polyol and a diisocyanate is placed on the substrate, followed by pressing, in the presence of a tertiary amine catalyst able simultaneously to catalyze the reaction of the polyol with the diisocyanate to form a polyurethane network and the reaction of the surface moisture with the diisocyanate to convert water molecules into polyurea.</p> |
