The present application relates to a quaternary nitrogen compound comprising a nitrogen heterocycle wherein: at least one polymeric substituent is bound to a ring atom of said heterocycle; and, an aromatic photoremovable group (PRG) is directly bound to a quaternary nitrogen ring atom of said heterocycle, the release of said aromatic photoremovable group under UV irradiation yielding a tertiary amine. The application further relates to the use of said quaternary nitrogen compound as a latent catalyst in a curable composition, the curing of which may be catalyzed or co-catalyzed by tertiary amines.
本申请涉及一种由氮杂环组成的季氮化合物,其中:至少一个聚合取代基与所述杂环的环原子结合;芳香族光可迁移基团(PRG)直接与所述杂环的季氮环原子结合,所述芳香族光可迁移基团在紫外线照射下释放产生叔胺。本申请还涉及将所述季氮化合物用作可固化组合物中的潜在催化剂,该组合物的固化可由叔胺催化或协同催化。
