An aqueous coating composition is prepared by dissolving a solid curing agent in polymerizable ethylenically unsaturated monomers and then emulsion polymerizing the monomers to form a polymer having groups reactive with the curing agent. An aqueous coating composition containing a solid crosslinker, for example a solid uretdione compound or other solid blocked isocyanate crosslinker, may be prepared in this way. Aqueous, thermosettable coating compositions so prepared may be applied to an article and cured to form a cured coating on the article. |
