  • Patent number: 5681889
    Abstract: The present invention provides hydrophilic crosslinked polymer fine particles made of a copolymer composed of:2-50% by weight of (a) a monoethylenic monomer having a polyoxyalkylene or polyvinylpyrrolidone chain,20-97% by weight of (b) a (meth)acrylamide type monoethylenic monomer,1-30% by weight of (c) a crosslinkable unsaturated monomer selected from the group consisting of compounds having, in the molecule, at least two polymerizable double bonds, and compounds having, in the molecule, at least one functional group selected from hydrolyzable silyl groups and 1,2-epoxy groups and one polymerizable double bond, and0-50% by weight of (d) other monoethylenic monomer. Said polymer fine particles are superior in polymerization stability as well as in dispersion stability during storage, undergoes no adverse effect by dispersion stabilizer owing to no use of said stabilizer, and are suitably used for formation of a hydrophilic film.

  • Patent number: 5104915
    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.
