SUSPENSION POLYMERIZATION TONER OF CORE-SHELL STRUCTURE WITH POSITIVE CHARGES AND PREPARATION METHOD |
| 摘要 |
Suspension polymerization toner of core-shell structure with positive charges comprises core-shell composite particles prepared by mixing composition forming toner core particles with aqueous dispersion liquid, carrying out a heating polymerization reaction to obtain suspension dispersion liquid of toner soft core particles, and carrying out a water-based polymerization reaction to form the core-shell composite particles of which an outer surface of the toner core particles are coated with the rigid shell layer with dense positive charges. |

1. A suspension polymerization toner of core-shell structure with positive charges, comprising core-shell composite particles prepared by mixing a composition forming toner core particles with aqueous dispersion liquid, carrying out a heating polymerization reaction to obtain a suspension dispersion liquid of toner soft core particles, then uniformly mixing a monomer emulsion forming a rigid shell layer and a cationic monomer with the suspension dispersion liquid of the toner soft core particles, and carrying out a water-based polymerization reaction to form the core-shell composite particles of which an outer surface of the toner core particles are coated with the rigid shell layer with dense positive charges. |
