摘要

本发明之课题系提供能够以相同之自我析出型被覆组成物对于多种金属材料具有同等之被膜析出性之自我析出型被覆组成物以及树脂被覆方法。本发明之解决手段系提供包含至少将水分散性或水溶性之阴离子性有机树脂、可溶解型3价铁源、可溶解型氟源、于分子内具有至少1个以上的羧基或羧基之盐之有机成分添加于水系溶剂之步骤，于前述步骤，溶解于前述水系溶剂中之相对于可溶解型3价铁之可溶解型氟之莫耳比([可溶解型氟之莫耳数])/([可溶解型3价铁之莫耳数]){此处，前述有机成分为有机酸金属盐时，为([可溶解型氟之莫耳数])/([可溶解型3价铁之莫耳数]+[来自有机酸盐之金属阳离子成分之莫耳数])}为1.0至3.2之多种金属材料用自我析出型被覆组成物之制造方法。;Provided is a method of producing the self-precipitation coating composition for various metal materials, comprising a step of at least adding an aqueous dispersible or water soluble anionic organic resin, a soluble 3-valent iron source, a soluble fluorene source, an organic component including one or more carboxyl groups or salts of carboxyl groups to an aqueous solvent, wherein, in the aforesaid step, the molar ratio of the soluble fluorene dissolved in the aqueous solvent with respect to the soluble 3-valent ion source ([molar number of the soluble fluorene])/([ molar number of the soluble 3-valent ion source]) {(in the case that the organic component is organic acid metal salt, ([molar number of the soluble fluorene])/([ molar number of the soluble 3-valent ion source] + [ molar number of metal cation from the organic acid salt]) is 1.0 to 3.2.
