Zusammenfassung:The coating material composition according to the present invention contains a nonionic water-dispersible resin (a), a phosphate-modified epoxy resin (b), a melamine compound (c), a silane coupling agent (d), and silica particles (e) having undergone ion-exchange with divalent metal ions. With respect to 100 parts by mass of the total of components (a), (b), and (c), the contained amount of the nonionic water-dispersible resin (a) is 60-94.5 parts by mass, the contained amount of the phosphate-modified epoxy resin (b) is 5-39.5 parts by mass, the contained amount of the melamine compound (c) is 0.5-10 parts by mass, and the contained amount of the silane coupling agent (d) is 0.3-5 parts by mass. 本发明的涂料组合物包含非离子性水分散性树脂(a)、磷酸改性环氧树脂(b)、三聚氰胺化合物(c)、硅烷偶联剂(d)和经2价的金属离子交换的二氧化硅颗粒(e)。并且,相对于(a)、(b)和(c)成分的合计100质量份,所述非离子性水分散性树脂(a)的含量为60~94.5质量份,所述磷酸改性环氧树脂(b)的含量为5~39.5质量份,所述三聚氰胺化合物(c)的含量为0.5~10质量份,所述硅烷偶联剂(d)的含量为0.3~5质量份。
