Microcapsule, microcapsule toner and process for preparation thereof |
| abstract |
A microcapsule comprising a capsule shell having at least one polymer structure selected from the group consisting of a polyurea resin, a polyurethane resin, a polyamide resin, a polyester resin and an epoxy resin and containing a block and/or graft copolymer formed by the vinyl polymerization of vinyl monomers initiated by the decomposition of a polymerization-initiating azo group which has been previously incorporated in the polymer structure. A process for the preparation of a microcapsule, which comprises the steps of: (a) allowing a first capsule shell-forming monomer and a second capsule shell-forming monomer, at least one of which contains a polymerization-initiating azo group, to undergo reaction in the inside and/or at the border of an oily drop to form a capsule shell containing a polymerization-initiating azo group and having at least one polymer structure selected from the group consisting of a polyurea resin, a polyurethane resin, a polyamide resin, a polyester resin and an epoxy resin, and then (b) allowing vinyl monomers to be vinyl-polymerized to said capsule shell. A microcapsule toner which comprises the above microcapsule in which the vinyl monomers contain a charge controlling group. A process for the preparation of a microcapsule toner which comprises the above process for the preparation of a microcapsule in which the vinyl monomers contain a charge controlling group. |
