Abstract

A non-yellowing one-package polyurethane coating composition containing an oxime-blocked polyisocyanate, an isocyanate-reactive material, and an imino-functional amino resin is provided. The coating composition is applied onto an acid-cured base coat and cured. The clear coat produced in this manner has good yellowness resistance and intercoat adhesion. Articles such as multi-layered coated substrates are prepared using the coating method of this invention. The coated substrates typically contain an acid-cured first layer and an adjacent layer derived from a curable composition containing an oxime-blocked polyisocyanate, an isocyanate-reactive material, and an imino-functional amino resin.
