The present invention provides the following aqueous coating composition. The aqueous coating composition comprises resin particles (A) having an average particle diameter of 300 to 1000 nm, a polyoxyalkylene group-containing polyol (B) having a number average molecular weight of 300 to 2000 and/or a diester compound (C), and a crosslinking agent (D); wherein the total solids content of the polyoxyalkylene group-containing polyol (B) and the diester compound (C) is 5 to 25 mass % based on the total solids content of the resin particles (A), the polyoxyalkylene group-containing polyol (B), the diester compound (C), and the crosslinking agent (D).

Aqueous coating composition

The problem to be solved by the present invention is to provide urethane resin particles that, when used as a component of a coating composition, enable the resulting coating composition to have excellent storage stability and excellent degree of freedom of adjustment of physical properties of the obtained coating film. The present invention provides core-shell type urethane resin particles having a core-shell structure in which the core comprises a urethane resin obtained by using a polyol component comprising polyether polyol, whereas the shell comprises a urethane resin obtained by using a polyol component comprising polycarbonate polyol.

Urethane resin particles

Provided is an acrylic urethane composite resin particles comprising an acrylic urethane graft resin (I) and a graft acrylic resin (II), the acrylic urethane graft resin (I) being synthesized in the presence of the graft acrylic resin (II), the graft acrylic resin (II) being a hydrophobic-chain- and hydrophilic-chain-containing resin having a weight average molecular weight of 5000 or more, the acrylic urethane graft resin (I) comprising an acrylic resin component and a urethane resin component, the acrylic resin portion of the acrylic urethane graft resin (I) being synthesized using, as constituent monomer components, 0.1 to 30 mass % of a polymerizable unsaturated monomer (1) containing a group having active hydrogen atom(s) reactive with an isocyanate group and 70 to 99.9 mass % of other polymerizable unsaturated monomer(s) (2).

Acrylic-urethane composite resin particles

An object of the present invention is to provide an aqueous coating composition comprising acrylic urethane composite resin particles that is excellent in storage stability and compatibility with other resin components and that achieves excellent performance of the obtained coating film, such as in finished appearance and water resistance. Provided as a means for achieving the above object is an aqueous coating composition comprising acrylic urethane composite resin particles (A), a reactive group-containing resin (B), and optionally a crosslinking agent (C), the acrylic urethane composite resin particles (A) comprising an acrylic urethane resin (I) and a graft acrylic resin (II), and being acrylic urethane composite resin particles prepared by synthesizing the acrylic urethane resin (I) in the presence of the graft acrylic resin (II), the graft acrylic resin (II) being a hydrophobic-chain- and hydrophilic-chain-containing resin having a weight average molecular weight of 5,000 or more.

The present invention provides an aqueous coating composition for use as an aqueous first colored coating composition in a multilayer coating-forming method, the coating composition containing an aqueous film-forming resin (A), a crosslinking agent (B), and acrylic urethane resin composite particles (C). The acrylic resin of the acrylic urethane resin composite particles (C) is obtained by using, as constituent monomers, 30 to 80 mass % of a polymerizable unsaturated monomer (c-1-1) having one polymerizable unsaturated group per molecule and having a Calkyl group, 1 to 20 mass % of a polymerizable unsaturated monomer (c-2) having two or more polymerizable unsaturated groups per molecule, and 0 to 69 mass % of a polymerizable unsaturated monomer (c-1-2) having one polymerizable unsaturated group per molecule and being other than the polymerizable unsaturated monomer (c-1-1).
