    • A curable resin composition for water-based paints comprising an emulsion polymer (A) bearing tertiary amino groups which is prepared by emulsion polymerizing a vinylic monomer having a tertiary amino group with other vinylic monomer in an aqueous medium and a compound (B) bearing both an epoxy group and a hydrolyzable silyl group as essential components and preferably containing an aqueous mixture (C) prepared by adding a neutralizing agent to a vinylic polymer (I) having acid groups and/or tertiary amino groups in such an amount as to neutralize at least 10 % of the acid groups and/or the tertiary amino groups and dispersing or dissolving the obtained mixture in water and/or a compound (D) other than the compound (B) which has a hydrolyzable silyl group and/or a silanol group. The paint prepared by using the composition is curable at ordinary temperatures and excellent in workability in coating and can give a cured coat excellent in the resistances to weather, solvents, chemicals, water and so on and reduced in environmental pollution.
    • 一种用于水性涂料的可固化树脂组合物,其包含通过在水性介质中将具有叔氨基的乙烯基单体与其它乙烯基单体乳液聚合制备的带有叔氨基的乳液聚合物(A)和带有两个 环氧基和可水解甲硅烷基作为必要组分,并且优选含有通过将中和剂加入到具有酸基和/或叔氨基的乙烯基聚合物(I)上而制备的水性混合物(C) 至少10%的酸基和/或叔氨基,并将得到的混合物分散或溶解在除具有可水解甲硅烷基和/或硅烷醇基的化合物(B)以外的水和/或化合物(D) 。 通过使用该组合物制备的涂料在常温下是可固化的,并且涂布的可加工性优异,并且可以得到耐候性,溶剂,化学品,水等优异的固化涂层,并减少环境污染。
