Abstract
Abstract The aqueous coating composition contains 2-50 percent of a filmforming binder in an aqueous medium and the binder comprises the following components: 1. AN ACRYLIC POLYMER WHICH COMPRISES A GRAFT COPOLYMER HAVING THE GENERAL STRUCTURE A-B where A is the backbone segment and B is the graft segment; the acrylic polymer is formed by polymerizing the following monomer units to form the backbone segment A methylmethacrylate, an alkyl methacrylate or an alkylacrylate, a hydroxalkylacrylate or methacrylate, a polymerizable carboxylic acid such as acrylic acid or methacrylic acid, and a grafting site monomer such as allymethacrylate to which a side chain segment B is grafted of acrylamide or methacrylamide and optionally a hydroxyalkylacrylate or a hydroxyalkylmethacrylate; 2. A LINEAR ACRYLIC POLYMER OF METHYL METHACRYLATE, AN ALKYL ACRYLATE OR AN ALKYL METHACRYATE, A HYDROXYALKYL ACRYLATE OR A HYDROXYALKYL METHACRYLATE, AND AN ETHYLENICALLY UNSATURATED CARBOXYLIC ACID WHICH IS 75-100 PERCENT NEUTRALIZED WITH AMMONIA OR AN AMINE; AND 3. A WATER-DISPERSIBLE CROSS-LINKING RESIN SUCH AS HEXAKIS(METHOXYMETHYL) MELAMINE; THE NOVEL COATING COMPOSITION FORMS A HIGH QUALITY FINISH FOR AUTOMOBILE AND TRUCK BODIES AND ALSO CAN BE UTILIZED FOR APPLIANCES SUCH AS REFRIGERATORS AND STOVES AND FOR CABINETS AND THE LIKE.
