    • This invention relates to a coating resin composition including an acrylic resin (A) having a hydroxyl group and an alicyclic epoxy group attached to side chains thereof, an alicyclic epoxy resin (B) having an epoxy equivalent weight of 100-1000, an organoalkoxy silane compound (C) having a glycidyl group and a hydrolyzable alkoxy silane group contained in one molecule thereof, and an aluminum chelate compound (D). The composition is stably storable, highly curable at low temperature (80° C. or below) and capable of producing a highly weatherable coating, and is useful particularly as a coating resin composition of a one-pack type and a coating derivable therefrom. The composition also exhibits various superior coating performance characteristics (bonding, appearance, weathering resistance, chemical resistance, solvent resistance and the like) in a well-balanced state.
    • 本发明涉及包含具有羟基的丙烯酸树脂(A)和侧链连接的脂环族环氧基的涂料树脂组合物,环氧当量为100-1000的脂环族环氧树脂(B),有机烷氧基硅烷 在一分子中含有缩水甘油基和可水解烷氧基硅烷基的化合物(C)和铝螯合化合物(D)。 该组合物可稳定地储存,在低温(80℃或更低)下可高度固化,并且能够生产高度耐候性的涂层,并且特别用作单组分型涂料树脂组合物和可从其得到的涂层。 该组合物在良好平衡的状态下也具有各种优异的涂布性能(粘合,外观,耐候性,耐化学性,耐溶剂性等)。
