    摘要: The present invention is directed to a coating composition for producing an adherent coating on a resinous substrate wherein the coating composition comprises a crosslinkable component comprising a polyol, a telechelic diol, and a crosslinking component. The crosslinking component comprises isocyanate functional molecules and the ratio of isocyanate functional groups to hydroxy functionality is in the range of from 0.1:1 to 0.8:1. The present invention is also directed toward a method of producing an adherent coating on a resinous substrate using the coating composition.
