摘要:
A composition comprised of a core and thereover a mixture of a first and second polymer, and wherein said first polymer contains a conductive component, and said second polymer is a poly(urethane).
摘要:
The present invention relates to a three-component optical photorefractive article having improved diffraction efficiency. The article comprises (i) nonphotoconductive polymer, (ii) benzimidazoline, and (iii) a sensitizer.
摘要:
A toner composition includes a binder, a colorant, and a surface additive package including a polydimethylsiloxane surface treated silica, a surface treated titania, and calcium sterate. The toner composition provides improved triboelectric charging properties.
摘要:
Use of a charge control agent in a toner, such as a magenta toner, to give an increased triboelectric charge is disclosed. The magenta toner may contain a magenta resin, such as xanthene. The charge control agent is a styrene-acrylate polymer, such as the following polymer of Formula II:
摘要:
A two dispenser system is used to replenish developer and toner in an electrostatic marking system. This two dispenser system replenishes toner and developer in a more accurate way since each of the dispensers are individually controlled and operated. Better quality prints and less waste is provided over extended usage periods.
