Abstract
Official abstract text for this publication.
The present invention is directed to an electrophoretic display fluid, in particular, pigment particles dispersed in a solvent or solvent mixture, and methods for their preparation. The pigment particles generated, according to the present invention, are stable in solvent under an electric field and can improve the performance of an electrophoretic display.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrophoretic fluid comprising charged polymer containing pigment particles and a charge control agent dispersed in a dielectric solvent or solvent mixture, wherein the polymer containing pigment particle comprises (a) a TiO 2 core pigment particle pretreated to have a surface area of more than 15 m 2 /gram; (b) polymer stabilizers; and (c) a silane linking moiety which attaches the polymer stabilizers to the surface of the core particle,…
