Super low melt toner having crystalline imides |
摘要 |
A toner includes a polymeric resin, optionally a colorant, and a small molecule crystalline imide having a molecular weight less than 1,000 g/mol. The polymeric resin may be an amorphous resin and a mixture of the amorphous resin and the crystalline imide may be characterized by a reduction in glass transition temperature from that of the resin and by the lack of a melting point for the crystalline imide as determined by differential scanning calorimetry, the enthalpy of fusion for the crystalline imide in the mixture being measured to be less than 10% of the enthalpy of fusion of the crystalline imide in pure form. Furthermore, the toner may be configured to have a crease fix minimum fusing temperature (MFT) less than or equal to the crease fix MFT of a benchmark ultra-low-melt emulsion aggregation toner. Suitable crystalline imides may include N-alkyl and N-aryl imides, such as N-benzylphthalimide. |
