  • Patent number: 7618701
    Abstract: In one aspect of the present system and method, an electrophotographic media includes a porous base media and a bi-modal pigmented composition disposed on the porous media that provides an increased resistance to blistering during pigment fusing. The bi-modal pigment may include a first pigment and a second pigment, the first pigment including particles having acicular morphology, and the second pigment including substantially spherical particles.

  • Patent number: 7413796
    Abstract: The present invention is drawn to a media sheet for color electrophotographic printing. The media sheet can comprise a base stock having a first side and a second opposing side, base coating layers coated directly on the first side and the second side, and receiving layers coated directly on the base coating layers. The base coating layers can include inorganic pigments, a binder, and a charge control agent. The receiving layers can include inorganic pigments, a binder, and a discharge control agent. In one embodiment, the binder of the receiving layers can be hollow particle pigments.
