Coating compositions capable of liquid application to substrates consist essentially of a curable film forming polyol-containing component and an organic reactive diluent. The reactive diluent is an organic compound containing a primary or secondary hydroxyl group and further characterized by having a retained solids value of greater than about 80 percent, a hydroxyl equivalent weight of from about 180 to about 800, and a liquid viscosity of less than about 10 poise at 60.degree. C. The coating compositions can be formulated to contain little or no volatile organic solvent and/or water.
