  • Publication number: 20010055722
    Abstract: A black toner composition comprises dried pigmented LC toner particles comprising a thermoplastic polymer and a carbon pigment having a BET value of up to about 140, and submicron particulate addendum material disposed on the dried pigmented LC toner particles. A process for forming the toner composition comprises: forming pigmented LC toner particles comprising a thermoplastic polymer and a carbon pigment having a BET value of up to about 140, drying the pigmented LC toner particles, and blending the dried pigmented LC toner particles with submicron particulate addendum material.

  • Patent number: 6031556
    Abstract: A process of forming a single color image which has improved abrasion resistance comprising:a) providing a thermal donor element comprising a heat-activatable image layer of a dye or pigment on a support, the image dye or pigment absorbing in the region of from about 300 to about 700 mn;b) providing a receiving element in superposed relationship with the thermal donor element;c) imagewise-exposing the thermal donor element by means of a laser or thermal head, thereby causing a change in the adhesion of at least a portion of the exposed areas of the heat-activatable layer to the receiving element or causing a portion of the exposed areas of the heat-activatable layer to diffuse into the receiver element;d) separating the thermal donor element from the receiver element, thus creating an image layer on either or both of the elements;e) charging either the thermal donor element or the receiver element containing the image layer to a given polarity or applying a voltage across the surface of the element which is a

  • Patent number: 5672458
    Abstract: A process of forming a single color, ablation image having improved abrasion resistance comprising:a) imagewise-heating by means of a laser an ablative recording element comprising a support having thereon an image layer comprising an image dye or pigment dispersed in a polymeric binder, which causes the image layer to ablate imagewise, the image layer having a near infrared-absorbing material associated therewith to absorb at a given wavelength of the laser used to expose the element, the image dye or pigment absorbing in the region of from about 300 to about 700 nm;b) removing the ablated material to obtain an image in the ablative recording element;c) either charging the imaged, ablative recording element to a given polarity or applying a voltage across the surface of the element which is attracted to a conductive surface behind the element;d) applying colorless, charged particles to the element which causes them to be electrostatically attracted to the surface of the image layer; ande) heat-fusing the par
