  Purpose of the present invention is consists in provision of a water-borne metallic color coating composition, a two-coating and one-baking application method therewith, and a multilayered coating film having an excellent flip-flop property thereby, wherein the water-borne metallic color coating composition has superior properties such as coloring property, recoat adhesion, chipping resistance, water-resistant adhesion, and the like. The water-borne metallic color coating composition can provide a coating film having the above-superior properties and an excellent flip-flop property, by a two-coating and one-baking application method, without disturbing the orientation of the luster color pigment(s) therein before/after an application of a clear coating composition and without adversely effecting on the flip-flop property. The present invention provides a water-borne metallic color coating composition comprising a film forming resin, a curing agent and a luster color pigment, wherein the film forming resin comprises an acrylic resin emulsion, which is obtainable by a two-stage emulsion polymerization, and which has an acid value within a range of from 1 to 30 mgKOH/g (as a basis of the solid resin content), a hydroxyl value within a range of from 10 to 150 mgKOH/g (as a basis of the solid resin content), and a particle size within a range of from 20 to 140 nm, and the curing agent is an aqueous dispersion of a hydrophobic melamine resin having a particle size within a range of from 20 to 140 nm.

  本发明的目的在于提供一种水性金属色涂料组合物、一种两涂一烤的涂布方法以及一种具有优异翻转性能的多层涂膜，其中水性金属色涂料组合物具有着色性能、重涂附着力、抗崩裂性、防水附着力等优异性能。本发明的水性金属色涂料组合物可以通过两涂一烤的涂覆方法提供具有上述优异性能和优良翻转性能的涂膜，在涂覆透明涂料组合物之前/之后不会扰乱其中的光泽颜料的取向，也不会对翻转性能产生不利影响。 本发明提供了一种包含成膜树脂、固化剂和光泽颜料的水性金属色涂料组合物，其中 成膜树脂包括丙烯酸树脂乳液，可通过两级乳液聚合获得，其酸值范围为 1 至 30 mgKOH/g（以固体树脂含量为基准），羟值范围为 10 至 150 mgKOH/g（以固体树脂含量为基准），粒径范围为 20 至 140 nm，以及 固化剂是疏水性三聚氰胺树脂的水分散体，其粒径在 20 至 140 纳米之间。
