CROSSLINKABLE COATING COMPOSITIONS AND METHOD OF USING THE SAME

摘要

Acrylyloxyalkanesulfonic acids, acrylamidoalkanesulfonic acids and their amine and ammonium salts are interpolymerized with other ethylenically unsaturated monomers including at least one such monomer which has at least one site for linking with an aminoplast resin. The interpolymer is admixed with an aminoplast resin to form a crosslinkable coating composition. The presence of the above sulfonic acids or sulfonates catalyzes the crosslinking reaction during baking and remains a part of the interpolymer.
