COATING COMPOSITIONS CONTAINING POLYURETHANE OR POLYUREA POLYMERS AND AMINO RESINS ABSTRACT A thermosettable coating composition comprises a hydroxy group-containing polyurethane, polyurea or poly- urethane/polyurea polymer, an amino cross-linker and op- tionally a catalyst and/or solvent. The polymer is obtained by self condensation of an hydroxyalkyl carbamate compound or condensation of such compound with a polyol and/or a polyamine. An applied coating of the composition is cured by heating to an elevated temperature, e.g., from about 200 to about 400°F (About 93 to 204°C).
