    • Laminates made with an adhesive comprised of a polymerizable composition containing compounds based on N-acylamido-piperazines are provided. Such compounds have the formula: ##STR1## wherein: R.sup.1, R.sup.2, and R.sup.3 are each independently selected from the group consisting of hydrogen and lower alkyl;B is a linking group selected from the group consisting of carbonyl, sulfonyl, amide, and carboxyl;n is one or zero; andR.sup.4 is a radical selected from the group consisting of a higher aliphatic group (i.e. at least four carbon atoms, preferably from about 6 to about 50 carbon atoms), a substituted higher aliphatic group, an alicyclic group, a heterocyclic group, a non-benzenoid aromatic group, and a substituted aromatic group. The adhesive coating is exposed to ultra-violet radiation sufficient to cause the compound to polymerize and thus cure the adhesive.
    • 提供了由包含基于N-酰基酰胺基 - 哌嗪的化合物的可聚合组合物的粘合剂制成的层压板。 这些化合物具有下式:其中:R 1,R 2和R 3各自独立地选自氢和低级烷基; B是选自羰基,磺酰基,酰胺和羧基的连接基团; n是1或0; 并且R 4是选自高级脂族基团(即至少四个碳原子,优选约6-约50个碳原子),取代的高级脂族基团,脂环族基团,杂环基团,非 - 苯并呋喃基和取代芳基。 粘合剂涂层暴露于足以使化合物聚合并因此使粘合剂固化的紫外辐射。

    • Polymerizable compositions containing compounds based on N-acylamido-piperazines are provided. Such compounds have the formula: ##STR1## wherein: R.sup.1, R.sup.2, and R.sup.3 are each independently selected from the group consisting of hydrogen and lower alkyl,B is a linking group selected from the group consisting of carbonyl, sulfonyl, amide, and carboxyl;n is one or zero;R.sup.4 is a radical selected from the group consisting of a higher aliphatic group (i.e. at least four carbon atoms, preferably from about 6 to about 50 carbon atoms), a substituted higher aliphatic group, an alicyclic group, a heterocyclic group, a non-benzenoid aromatic group, and a substituted aromatic group. Compositions containing these compounds which are stable against gelation can be prepared. The compound is preferably present in said composition in a major amount on a mole percent basis of the polymerizable monomers. These polymerizable compositions are useful as coatings, particularly in formulations containing a photoinitiator susceptible to ultra-violet radiation. The coating is exposed to ultra-violet radiation sufficient to cause the compound to polymerize and thus cure the coating.
    • 提供了含有基于N-酰氨基 - 哌嗪的化合物的可聚合组合物。 这些化合物具有下式:其中:R 1,R 2和R 3各自独立地选自氢和低级烷基,B是选自羰基,磺酰基,酰胺和羧基的连接基团; n是1或0; R4是选自高级脂族基团(即至少四个碳原子,优选约6-约50个碳原子),取代的高级脂族基,脂环基,杂环基, 苯环芳基和取代芳基。 可以制备含有对胶凝稳定的化合物的组合物。 该化合物优选以所述可聚合单体的基于摩尔百分数计的主要量存在于所述组合物中。 这些可聚合组合物可用作涂层,特别是在含有对紫外线辐射敏感的光引发剂的制剂中。 将涂层暴露于足以使化合物聚合并因此使涂层固化的紫外辐射。
