Aromatic polyurethane dispersions were synthesized with dimethylolpropionic acid (DMPA), isophorone diisocyanate(IPDI), and aromatic polyester polyol, prepared chemical reaction of esterification and polycondensation, The structures of these polyurethanes were characterized by FT0IR, H-NMR, and the properties were measured with DSC, TGA. Increase aromatic polyol contents made of unplasticized polyurethane dispersions. As the aromatic structures in polyurethane dispersions introduced, glass transition temperature(T_(g)) and thermal stability increased. In this polyurethane dispersions increased with DMPA concentrations, particle size decreased and dispersible stability increased and T_(g) increased over 50℃.

Physical and chemical properties of high brightness waterborne metallic paint for automotive plastic interior were investigated. High brightness waterborne metallic paint with metallic flake made by physical vapor deposition showed good flop index, and polyacrylate resin with high glass transition temperature had better physical properties on long term reliability test. In according to painting conditions of this paint, flop index was highly influenced by humidity of paint booth and NV (Non Volatile) of the paint. High brightness waterborne metallic paint satisfied all of the reliability specifications in automotive interior.
