The invention pertains to a coating composition comprising a first compound comprising at least one bicyclo- or spiro-orthoester group and a second compound comprising at least two hydroxyl-reactive groups. The invention also comprises a process for curing the present coating composition. More particularly, the latent hydroxyl groups of the bicyclo- or spiro-orthoester groups have to be deblocked and reacted with the hydroxyl-reactive groups of the second compound if the present coating composition is to be cured. Further, a process for making bicyclo-orthoester compounds from the corresponding oxetane compound is described, as are polymers comprising at least one bicyclo- or spiro-orthoester group.
本发明涉及一种涂层组合物,包括第一化合物,该化合物包括至少一个双环或螺环正酯基团和第二化合物,该化合物包括至少两个羟基反应基团。本发明还包括一种用于固化本涂层组合物的方法。更具体地说,如果要固化本涂层组合物,则必须去除双环或螺环正酯基团的潜在羟基,并将其与第二化合物的羟基反应基团反应。此外,本发明还描述了一种从相应的氧杂环丙烷化合物制备双环正酯化合物的方法,以及包含至少一个双环或螺环正酯基团的聚合物。
