摘要： A cationic electrodeposition paint composition suitable for coating a road wheel of an automotive vehicle, comprises:
an acrylic cationic resin (A) which is a copolymer of a first vinyl monomer having at least one secondary or tertiary amino group, a second vinyl monomer having a hydroxyl group, and a third vinyl monomer other than the first and the second vinyl monomers;
a urethanated epoxy system cationic resin (B) which is a reaction product between a urethanated epoxy resin and at least one primary or secondary amine;
a hardener resin (C) of a blocked isocyanate which regenerates isocyanate group by thermal decomposition under heating; and
a cationic cross-linked resin particulate (D) which is an addition reaction product between an epoxy resin derivative (d-1) having not less than two primary amines per molecule and a polybutadiene derivative (d-2) having not less than two α, β-ethylenioally unsaturated groups per molecule, the resin particulate having an average particle size of from 0.01 µ to 1 µ;
the acrylic cationic resin (A) being present in an amount from 20 to 70 parts by weight per 100 parts by weight of the total solids content of the acrylic cationic resin (A), the urethanated epoxy system cationic resin (B), the blocked isocyanate hardener resin (C) and the cationic cross-linked resin particulate (D); the urethanated epoxy system cationic resin (B) being present in an amount of from 5 to 50 parts by weight per 100 parts by weight of said total solids content; the hardener resin (C) being present in an amount of from 10 to 40 parts by weight per 100 parts by weight of said total solids content; and the cationic cross-linked resin particulate (D) being present in an amount of from 1 to 20 parts by weight per 100 parts by weight of said total solids content.
