Preparation of base‐amplifying microcapsules and their application to photoreactive materials

Abstract

Base‐amplifying (BA) microcapsules are developed, and it is found that they work more effectively than dispersed molecular base amplifiers in anionic UV curing systems with a water‐soluble epoxy resin. The pencil‐hardness value of 2H is obtained with the BA microcapsules after 5000 mJ cm−2 of 365 nm light irradiation and subsequent heating at 100 °C for 60 min.
