  • Publication number: 20120208035
    Abstract: An object of the present invention is to provide an aqueous coating composition comprising an (A) aluminium pigment treated with molybdic acid and a (B) condensed polycyclic pigment. The aqueous coating composition can achieve a small difference between the color of a coating film formed by application of the coating composition after storage and a color of the coating film formed by application of the coating composition before storage. The aqueous coating composition of the present invention inhibits hydrogen gas generation, and thus has excellent storage stability. The present invention provides an aqueous coating composition, comprising: (A) aluminium pigment treated with molybdic acid; (B) condensed polycyclic pigment; (C) resin having an aromatic ring with a nitro group bonded thereto; and (D) film-forming resin.

  • Patent number: 5929158
    Abstract: The invention provides a non-aqueous polymer dispersion wherein a particulate polymer is dispersed in an organic solvent containing a dispersion stabilizer resin, the polymer being insoluble to the organic solvent and containing a fluoroalkyl group-containing (meth)acrylate as a monomer component. The invention further provides a curable composition comprising the non-aqueous polymer dispersion, a hydroxyl group containing resin and at least one crosslinking agent selected from the group consisting of amino resins, tris(alkoxycarbonylamino)triazines, polyisocyanate compounds and blocked polyisocyanate compounds. A highly stain-resistant coating film can be formed using the dispersion or composition of the invention.
