    • Provided is a mat anionic electro-deposition coating composition having excellent storage stability, finishing property in coating and dies mark hiding property. The mat anionic electro-deposition coating composition comprises an emulsion which is produced by performing a first step of radically co-polymerizing a hydroxyl group-containing unsaturated monomer(a), a carboxyl group-containing unsaturated monomer(b) and other radical polymerizable unsaturated monomer(c) to obtain a water-dispersible vinyl copolymeric resin(A), and a second step of mixing the water-dispersible vinyl copolymeric resin(A) with an epoxy compound(d) having at least one of an epoxy group and a hydroxy silane group in one molecule by heat to obtain an aqueous resin(I), and sequently mixing the aqueous resin(I), a cross-linking agent(II) and a basic compound, followed by dispersing in water.
    • 本发明提供一种具有优异的保存稳定性,涂布整理性和模具标记隐藏性的垫阴离子电沉积涂料组合物。 垫阴离子电沉积涂料组合物包含通过使含羟基的不饱和单体(a),含羧基的不饱和单体(b)和其它自由基聚合的不饱和单体(a)自由基共聚的第一步骤而制备的乳液 单体(c),得到水分散性乙烯基共聚树脂(A),第二步是将水分散性乙烯基共聚树脂(A)与环氧化合物(d)中的至少一种环氧基和 羟基硅烷基团,通过加热得到水性树脂(I),并依次混合水性树脂(I),交联剂(II)和碱性化合物,然后分散在水中。
