Abstract
Abstract A fiber-reinforced urethane molding comprises a molded urethane layer reinforced by inclusion of reinforcing fibers, and a hard urethane-based coating film overlaid on the surface of the molded urethane layer. The hard urethane-based coating film contains aluminum flakes dispersed therein in an amount within the range of 5% to 40% by weight, whereby projection of the reinforcing fibers out of the surface of the molded urethane layer is prevented by the aluminum flakes and the coated urethane molding exhibits high distinctness of image gloss.
