  • Publication number: 20070237903
    Abstract: The present invention provides an thermosetting aqueous coating composition comprising (A) 100 parts by weight of a hydroxy- and carboxy-containing water-soluble resin having a weight average molecular weight of 500 to 200,000, a hydroxy value of 1 to 200 mg KOH/g, and an acid value of 10 to 100 mg KOH/g, and (B) 10 to 100 parts by weight of a luster pigment; the coating composition being applied so as to form a film with a thickness of 3,000 to 8,000 nm when cured; and the coating composition, when formed into a deposited coating with a solids content of 40 wt. %, having a viscosity of 4×102 to 1×104 mPa·s as measured at 20° C. and a shear rate of 0.1 sec?1.

  • Patent number: 6635312
    Abstract: The present invention provides a method for providing a paint film with improved cratering resistance, comprising making adjustments in the application of a liquid paint to a substrate so that the wet paint film immediately after application has a viscosity of 0.2 to 1.0 Pa·s at a strain rate of 5 sec−1 at 20° C., as measured by the static flow method, and has a storage modulus/loss modulus ratio within the range of 0.1 to 0.25 at an angular frequency of 10 rad/sec at 20° C., as measured by the oscillation method.
