ABSTRACT OF THE DISCLOSURE ONE PACK TYPE THERMOSETTING POLYURETHANE COATING COMPOSITION Disclosed are a thermosetting polyurethane coating composition of one-pack type which comprises a product obtained by reacting (i) an isocyanate component having at least one oxadiazinetrione ring obtained by the reaction of bis(isocyanatomethyl) cyclohexane with carbon dioxide with (ii) a polyol component at such a proportion as to satisfy the relations : the number of hydroxyl groups > the number of free isocyanate groups and the number of oxadiazinetrione rings/(the number of hydroxyl groups - the number of free isocyanate groups) = 0.1 to 10, and a process for producing the coating composition. The composition has excellent storage stability and the cured coatings have no problems of yellowing and pin-holes and are excellent in mechanical properties, chemical resistance and weather resistance.
