Microencapsulation by in-situ polymerization of multifunctional epoxy resins |
| abstract |
A method of forming microcapsules by in-situ polymerization is disclosed. The microcapsules are prepared by forming an organic solution containing a polyfunctional amine curing agent and an epoxy resin select from the group consisting of 4-glycidyloxy-N, N-di-glycidyl aniline and methylolated bisphenol A based epoxy resins. This organic solution is then dispersed or emulsified within an aqueous continuous phase. The amine agent then polymerizes the epoxy resin, which migrates to the interface between the continuous and discontinuous phases to form the microcapsular wall. The resulting microcapsules are characterized by relatively high impermeability and are especially useful in carbonless copying systems. |
