| 摘要 |
<p>The present invention relates to a dry toner composition, comprising a colorant and a binder resin. This binder resin comprises a physical mixture of an amorphous polymer and a crystalline phase-containing polymer. The binder resin is being obtainable by blending or mixing the amorphous polymer and the crystalline phase-containing polymer. Herein, the amorphous polymer and the crystalline phase-containing polymer are compatible in a molten state mixture and show no significant phase separation upon cooling of the molten state mixture. The crystalline phase-containing polymer has a melt energy greater than or equal to 35 J/g, and the amorphous polymer has a Tg greater than or equal to 35°C. The dry toner composition comprises from 3 to 75% by weight of the crystalline phase-containing polymer.</p> |
