Abstract: An object of the present invention is to provide an aqueous coating composition capable of forming a coating film having a superior finishing appearance. The present invention provides an aqueous coating composition comprising a polyester resin containing a predetermined or greater amount of long chain, straight-chain dicarboxylic acid and/or straight-chain diols having a predetermined or greater carbon number and having hydroxy groups and acid values within predetermined ranges; a urethane-associated thickener having a hydrophobic group and/or a polyacrylicacid-based thickener having a hydrophobic group; a curing agent; and a hydrophobic solvent, wherein the contents of the thickener and the hydrophobic solvent are within a specific range based on the gross amount of the polyester resin and the curing agent. The present invention also provides a method for forming a multilayer coating film using the aqueous coating composition.

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.
