摘要:
Low fix temperature toner resins are fabricated by a reactive melt mixing process wherein polymer resins are cross-linked at high temperature and high shear. The resins are particularly suitable for high speed fusing, show excellent offset resistance and wide fusing latitude and superior vinyl offset propertieS.
摘要:
A low melt toner resin with low minimum fix temperature and wide fusing latitude contains a linear portion and a cross-linked portion containing high density cross-linked microgel particles, but substantially no low density cross-linked polymer. The resin may be formed by reactive melt mixing.
摘要:
Toner compositions comprising resin particles, pigment particles, and as a charge enhancing additive inner salts wherein the negative charge center is covalently attached to the positive charge center. Also disclosed are developer compositions comprising the aforementioned toner components and carrier particles, which compositions are particularly useful for the development of electrostatic latent images. Additionally, there can be selected for the toner and developer compositions mixtures of charge enhancing additives including mixtures of the aforementioned inner salts and second charge enhancing additives such as quaternary ammonium compounds.
