  Linear crosslinkable polyurethanes obtained from (a) at least one diisocyanate having 2 to 30 carbon atoms, (b) at least one aliphatic or cycloaliphatic diol having 2 to 30 carbon atoms, to whose carbon chain at least one carboxyl group is covalently bonded, and some or all of said carboxyl groups have been esterified with an olefinically unsaturated C 3 -C 8 alcohol or with the glycidyl ester of an olefinically unsaturated C 3 -C 8 carboxylic acid, and (c) optionally at least one aliphatic or cycloaliphatic diol having 2 to 30 carbon atoms, to whose carbon chain at least one carboxyl group is covalently bonded. The polyurethanes are suitable, alone or as a mixture with other reactive components, for thermal and/or photochemical crosslinking in crosslinkable compositions for the production of mouldings, coatings and in particular solder masks.

  该文段描述了由以下成分制备的线性交联聚氨酯：（a）至少含有2到30个碳原子的二异氰酸酯，（b）至少含有2到30个碳原子的脂肪族或环脂族二醇，其碳链上至少有一个羧基共价结合，并且其中一些或全部羧基已经与烯丙基未饱和的C3-C8醇或烯丙基未饱和的C3-C8羧酸的环氧基酯化合物酯化，以及（c）可选地至少含有2到30个碳原子的脂肪族或环脂族二醇，其碳链上至少有一个羧基共价结合。这些聚氨酯可以单独使用或与其他反应性组分混合，用于热交联和/或光交联交联可制备成型、涂层和特别是钎焊面具的交联组合物的生产。
