ABSTRACT:
Microcapsule toners comprise a polymeric shell and a core containing colorants and a polymer binder. Part of the polymer binder is chemically grafted to the shell polymer. A process of preparing the microcapsule toners involves a shell forming interfacial polycondensation and a core binder forming free radical polymerization. The grafting of core binder to the shell is accomplished via the involvement of a polyfunctional reagent capable of reacting with both the shell and core monomers, or involvement of a shell monomer bearing a core monomer functionality.
