Novel Fluorinated silicon (IV) phthalocyanines and naphthalocyanines for electrophoretic, magnetophoretic or electromagnetophoretic display |
摘要 |
This invention relates to stable colorants of high extinction coefficient and high solubility or dispersibility for an electrophoretic, magnetophoretic or electromagnetophoretic display. More particularly, it relates to stable colorants for a microcup-based electrophoretic or electromagnetophoretic display the cells of which are filled with charged and/or magnetic particles dispersed in a halogenated, preferably a fluorinated, solvent. The use of the stable colorants allows the display to be of superior contrast ratio and longevity, and suitable for high-quality imagery applications.
