Abstract
A sprayable metallic-tone lacquer composition comprising a tinted polymer-solvent system containing approximately 5% to about 15% by weight of a transparent film-forming resin consisting of a mixture of an acrylic copolymer and nitrocellulose, and about 1-5% by weight of a metal-simulating dye dissolved in about 80-90% by weight of an organic solvent blend. The solvent blend preferably comprises about 25-35% by weight of acetone; 5-15% by weight each of propylene glycol methyl ether acetate, toluene, and methyl isobutyl ketone; and 5-10% by weight each of butyl benzyl phthalate, isobutyl acetate and isopropyl alcohol. The lacquer composition are particularly adapted for aerosol application and are prepared by dissolving appropriate amounts of the clear resin mixture in the solvent blend and adding the soluble dye, then pressurizing the resulting tinted resinous solution with a mutually compatible aerosol propellant in a suitable aerosol dispensing container.
