<p>PCT No. PCT/US83/01599 Sec. 371 Date Oct. 13, 1983 Sec. 102(e) Date Oct. 13, 1983 PCT Filed Oct. 13, 1983 PCT Pub. No. WO85/01695 PCT Pub. Date Apr. 25, 1985.This invention is directed to flexible basecoat/clearcoat coating systems which have excellent adherence to metal and plastic substrates and possess superior weathering properties. The clearcoat composition comprises hydroxy-containing urethane modified polyester, made by reacting a urethane modified diol with polyol and diacid component, crosslinkable with amine-aldehydes. The basecoat composition comprises hydroxy-containing urethane modified polyesters, made by reacting hydroxy functional polyester with diisocyanate, crosslinkable with amine-aldehyde and pigment. Optionally, either or both compositions may comprise a high molecular weight linear polyurethane.</p> |
