Abstract

A transparent adhesive coating or film based on polyurethane. The coating or film comprises a polurethane formed from at least one aliphatic or cycloaliphatic diisocyanate, at least one polyol chosen from among the polyether diols, the polycaprolactone diols, the polycarbonate diols, and the polybutadiene diols, and at least one chain-lengthening agent which is a product of the reduction of dimeric acid to a diol. The adhesive coating or film is employed in laminated panes of glass and/or plastic material.
