The coating film-forming composition is a solution of pH 4 to 10 and includes an aromatic compound having an amino group and an aromatic ring in one molecule, a polybasic acid having two or more carboxy groups, and an oxidizing agent. As the oxidizing agent, hypochlorous acid, chlorous acid, chloric acid, perchloric acid, persulfuric acid, percarbonic acid, hydrogen peroxide, organic peroxides, or the like is used. The aromatic compound preferably contains a nitrogen-containing aromatic ring, and more preferably contains a primary amino group or a secondary amino group. The coating film-forming composition is used for, for example, forming a coating film on surface of a metal member.
涂膜成膜组合物是一种 pH 值为 4 至 10 的溶液,包括一种在一个分子中具有一个氨基和一个芳香环的芳香族化合物、一种具有两个或两个以上羧基的多基酸和一种氧化剂。作为氧化剂,可使用次氯酸、亚氯酸、氯酸、高氯酸、过硫酸、过碳酸、过氧化氢、有机过氧化物等。芳香族化合物最好含有含氮芳香环,更优选含有伯氨基或仲氨基。涂膜成膜组合物用于例如在金属构件表面形成涂膜。
