摘要： An epoxy composition for applications such as one-part adhesives, coatings, prepreg and molding compounds that includes leuco dyes, particularly those comprising a N,N-dialkylamino-, N,N-diarylamino-, or cycloalkylamino- functional group on one of the aromatic rings, as a co- catalyst or co-curing agent. The use of the leuco dye co-catalyst provides improved curing speed of the epoxy composition comprising a latent curing agent /catalyst such as Novacure imidazole microcapsules while maintaining the shelf-life stability. The epoxy may also include a secondary co-catalyst that includes amides and lactams, particularly those comprising a N,N-dialkylamino-, N,N-diarylamino-, or dicycloalkylamino- functional group. Secondary cocatalysts of low mobility at the storage conditions, such as those with a long chain substitutent, dimeric or oligomeric amides or lactams, are particularly preferred. The improved epoxy composition is implemented as adhesives for manufacturing an anisotropic conductive film (ACF) and also for connecting, encapsulating, or packaging of electronic devices.
摘要翻译：一种用于诸如单份粘合剂，涂料，预浸料和模塑料的应用的环氧组合物，其包括无色染料，特别是包含N，N-二烷基氨基 - ，N，N-二芳基氨基 - 或环烷基氨基官能团的那些芳环，作为助催化剂或共固化剂。无色染料助催化剂的使用提供包含潜在性固化剂/催化剂如Novacure咪唑微胶囊的环氧组合物的改进的固化速度，同时保持保质期的稳定性。环氧树脂还可以包括二级助催化剂，其包括酰胺和内酰胺，特别是包含N，N-二烷基氨基 - ，N，N-二芳基氨基 - 或二环烷基氨基官能团的那些。在储存条件下的低迁移率的二级助催化剂，例如具有长链取代基，二聚或低聚酰胺或内酰胺的二级助催化剂是特别优选的。改进的环氧组合物被实施为用于制造各向异性导电膜（ACF）的粘合剂以及用于电子器件的连接，封装或封装的粘合剂。
