Abstract:
A gyricon display containing modified particles is disclosed. the gyricon display has an arrangement of bichromal or polychromal elements which are disposed between a first and second electrode. One of the electrodes is substantially visually transparent. The display also has menas for creating a potential difference between the two electrodes. Also, each bichromal element has two hemispheres, wherein one of the hemispheres has at least a surface containing at least one modified colored pigment having attached at least one organic group and the other hemisphere has at least a surface with a different color and different electrical property. The organic group preferably includes at least one ionic, ionizable group, or both. Each bichromal or polychromal element is enclosed with a shell wherein a liquid is present between the shell and the element so the element is free to rotate in response. Methods of making the gyricon display are also disclosed.
Abstract:
PROBLEM TO BE SOLVED: To provide a carbon black product having an organic group attached to the carbon black. SOLUTION: In a process, at least one diazonium salt is reacted with carbon black in the absence of an outer applied electric current sufficient to reduce the diazonium salt. In another process, at least one diazonium salt is reacted with carbon black in the presence of a protonic reaction medium. The carbon black product can be produced in the processes. Such the carbon black is useful for uses in plastic compositions, rubber compositions, paper compositions, and fiber compositions. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract:
The present invention relates to a process for preparing surface-modified colored pigments. The process includes the steps of: preparing a reaction batch comprising a treating agent and a diazotizing agent; adding a colored pigment to the batch; and mixing the colored pigment and the batch under high shear conditions to form a reaction product comprising a surface-modified colored pigment. The treating agent has an organic group which comprises at least one diazotizable group. In a preferred embodiment the diazotizable group comprises a) at least one aromatic group or at least one C1-C20 alkyl group, and b) at least one ionic group, ionizable group, nonionic group, or a mixture thereof. The surface-modified colored pigments prepared by the process of the present invention have been found useful in aqueous or solvent based compositions and particularly in ink jet ink compositions.
