ELECTROPHORESIS PARTICLE DISPERSION, IMAGE-DISPLAYING MEDIUM, AND IMAGE DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide electrophoresis particle dispersion having high white color reflectance and hardly precipitating in a dispersant as compared with an inorganic white pigment. SOLUTION: This electrophoresis particle dispersion is obtained by dispersing the electrophoresis particles consisting mainly of an alkylenebismelamine derivative expressed by general formula (I) [wherein R is H, 1-4C lower alkyl or alicyclic; R1to R4are each independently H or 1-4C lower alkyl; R1with R2and R3with R4may form a heterocyclic group together with a nitrogen atom; and X is 2-3C lower alkylene] in a nonpolar solvent.
