POLYMER PARTICLE FOR ELECTROPHORETIC DISPLAY ELEMENT, METHOD FOR PRODUCING POLYMER PARTICLE FOR ELECTROPHORETIC DISPLAY ELEMENT, AND DISPERSION LIQUID

摘要

PPROBLEM TO BE SOLVED: To provide an electrophoretic polymer particle having high electrophoresis and dispersion stability, and sufficiently hiding an applied color, and also to provide a producing method thereof, and particle dispersion liquid for an electrophoretic display element containing the electrophoretic polymer particle. PSOLUTION: The polymer particle for the electrophoretic display element has an average particle diameter of 100 nm to 10 m including a pigment. The pigment is present only in a polymer phase. At least one air gap is formed in the polymer particle. PCOPYRIGHT: (C)2011,JPO&INPIT
