ABSTRACT:
A lacquer consisting essentially of a uniform dispersion or solution of 8% to 16% polymerized lower alkyl acrylate and/or methacrylate having 1% to 20% free carboxyl groups, 2.5% to 10% polymethyl or polyethylmethacrylate, 5% to 10% water-soluable, thermosetting melamine resin, the balance being a volatile medium consisting essentially of water and a lower alkanol when deposited on a plastic film and cured at a temperature at least sufficient to volatilize the solvent, forms a transparent, abrasion-resistant coating.
