<p>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 maintaing 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 cycloalkylamino- functional group. The improved epoxy composition is implemented as adhesives for manufacturing an anisotropic conductive film and also for connecting, encapsulating, or packaging of electronic devices.</p> |
