    • Thermosetting composition is excellent in storage stability, is useful as one component thermosetting composition, gives cured products having excellent chemical properties, physical properties and weathering resistance and is favorably utilized in coating compositions, ink, adhesive and molded plastics.
      The thermosetting composition comprises a compound having in the molecule two or more carboxyl groups blocked by a vinyl ether compound, a vinyl thioether compound or a hetero compound having a vinyl type double bond and oxygen or sulfur as the hetero atom, a compound having two or more reactive functional groups which can form a chemical bond with the blocked carboxyl compound by heating and optionally a thermal latent acid catalyst. The blocked carboxyl group of the first compound and the reactive functional group of the second compound may be comprised in the same molecule.
    • 热固性组合物的保存稳定性优异,作为一种组分的热固性组合物是有用的,得到具有优异的化学性质,物理性质和耐候性的固化产物,并且有利地用于涂料组合物,油墨,粘合剂和模制塑料中。 热固性组合物包含在分子中具有被乙烯基醚化合物封闭的两个或多个羧基,乙烯基硫醚化合物或具有乙烯基型双键的杂化合物和氧或硫作为杂原子的化合物,具有两个或 可通过加热和任选的热潜酸催化剂与封端的羧基化合物形成化学键的更多的反应性官能团。 第一化合物的封端羧基和第二化合物的反应性官能团可以包含在相同的分子中。
