    摘要: A system and method create an authentication mark on a recording medium by depositing marking material on a medium in an image area to create a marking material image and to create a marking material authentication image. The marking material comprises an ultraviolet curable phase change ink composition comprising an optional colorant and a phase change ink vehicle comprising a radiation curable monomer or prepolymer; a photoinitiator; a reactive wax; and a gellant. A predetermined amount of additional marking material is further deposited upon the medium in the authentication image area to increase an amount of marking material associated with the marking material authentication image in the authentication image area. The fixed marking material associated with the authentication image area is a tactilely perceptible authentication mark having a height, with respect to a surface of the medium, that is tactilely perceptible, wherein the fixed marking material associated with the marking material image area is tactilely non-perceptible.

    摘要: Set forth is a method of forming an electrophoretic display device that includes locating a multiplicity of individual reservoirs containing a display fluid between conductive substrates, at least one of which is transparent, to form a device, wherein the display fluid comprises at least two sets of particles in a liquid medium, the at least two sets of particles exhibiting a different color, and charging each of the sets of particles to have a different charge via application of an electric field to the device. This field induced charging of the sets of differently colored particles enables low conductivity particles with superior electrophoretic mobility to be achieved.

    摘要: A process for latex preparation including: a first heating of a mixture of at least one free radical polymerizable monomer compound, a free radical initiator compound, and a stable free radical compound to form a latomer mixture with from about 1 to about 8 percent conversion of the monomer compound to an oligomeric compound of the formula I—R′—SFR, wherein R′ is an oligomer comprised of from about 1 to about 30 monomer units, I— is a covalently bonded free radical initiator fragment arising from the free radical initiator compound, and —SFR is a covalently bound stable free radical group; dispersing the resulting latomer mixture in water with high shear to form a miniemulsion; and a second heating of the miniemulsion, wherein there results a high stability polymer particle latex which contains a polymer with a high monomer to polymer conversion of from about 98 to about 100 weight percent and a narrow polydispersity of from about 1.1 to about 2.0.
