摘要： A cationic electrodeposition-coating resin is prepared by reacting(1) a polyisocyanate with(2) a polyol and(3) a monofunctional blocking agent at a molar ratio of excess of isocyanate groups to total of hydroxyl groups of the polyol and functional groups of the monofunctional blocking agent to obtain an intermediate (A) having isocyanate groups; and reacting a tertiary amine having at least two hydroxyl groups with the intermediate (A) at a molar ratio of excess of hydroxyl groups of the tertiary amine to isocyanate groups of the intermediate (A); and cationizing the resulting reaction product (B).
