摘要:
An electrophoretic particle dispersion including: electrophoretic particles including first particles having a surface thereof covered with a curvature-adjustment portion formed from a curvature-adjustment material, a curvature at the surface of the curvature-adjustment portion being greater than the curvature of the first particles that do not include the curvature-adjustment portion; a crosslinking agent capable of binding the electrophoretic particles via a reversible crosslinked structure; and a dispersing medium in which the electrophoretic particles and the crosslinking agent are dispersed.

A particle dispersion for display including: first particles for display including a colorant and a first polymer having a first charging group, the first particles for display being movable in response to an electric field; a first polymeric dispersant attached to the first particles for display; second particles for display including a colorant and a second polymer having a second charging group, the second particles for display being movable in response to an electric field; a second polymeric dispersant attached to the second particles for display; and a dispersing medium in which the first particles for display and the second particles for display are dispersed, the first polymeric dispersant and the second polymeric dispersant having different weight average molecular weights so that the first particles for display and the second particles for display start moving upon application of different voltages.
摘要:
Electrophoretic particles including mother particles and a dispersant that covers the surface of the mother particles, the mother particles including a resin and a colorant, and the dispersant having a structure represented by the following Formula (1): wherein in Formula (1), R1 represents a dimethyl siloxane chain that comprises two or more dimethyl siloxane structures that are linked together, the dimethyl siloxane chain being optionally substituted by an organic group; R2 represents a hydrogen atom or a methyl group; Ar1 represents an organic group having an aromatic group; a represents an integer of from 8 to 88; b represents an integer of from 12 to 82; c represents an integer of from 0 to 30; f represents an integer of from 1 to 3; the total of a, b and c is 100; and the ratio of unit (b) in the dispersant having a structure represented by Formula (1) is about 50% by weight or less.
