| 摘要 |
The invention provides non-gelled polymers containing integral isocyanato groups, which can be formulated into coating compositions. The polymers are derived preferably from polymerizable, ethylenically unsaturated blocked mono-isocyanato group-containing monomer, hydroxyl group-containing monomer and an amino group-containing monomer and/or carboxyl group-containing monomer. The coating compositions, particularly the electrodepositable compositions of this invention, possess excellent properties of wet appearance, substrate adhesion, hardness, chemical resistance and glossy appearance.
