Abstract: A process for forming a coating film, the process comprising the steps of coating a substrate with a dark color coating comprising a thermosetting resin composition, a coloring pigment, carbon black pigment and a light-iridescent pigment, and coating the dark color coat with a color clear coating comprising a thermosetting resin composition and carbon pigment. The process permits forming a coating film having superior aesthetic appearance, wherein the coating film exhibits an excellent light-iridescent, or pearl-like, appearance at the highlight portion and a dark color appearance having an excellent pitch-black feeling without muddiness in the shade portion.

Abstract: A method for producing millable polyurethanes by first producing a poly-.epsilon.-caprolactone based diol, the poly-.epsilon.-caprolactone based diol containing a controlled average number of caprolactone units and having a molecular weight distribution; and reacting the poly-.epsilon.-caprolactone based diol with a diisocyanate to produce a polyurethane with a restricted crystallizability having a rubber elasticity. The resulting millable polyurethanes exhibit excellent hydrolysis resistance, show no crystallization at low temperatures and have excellent mechanical properties.
