| 发明名称 | Hybrid emulsion aggregate toner | ||
| 摘要 | Emulsion aggregate toner compositions that use two different emulsion aggregation (EA) technologies. Namely, there is provided an emulsion aggregation toner that comprises a base resin composed of both styrene-acrylate and polyester resins. Such hybrid emulsion aggregation toner compositions are lower in cost but still maintain desirable developer properties like low minimum fusing temperature (MFT) and lower dielectric loss. | ||
