작용화된 안료를 생성하도록 글리시딜 메타크릴레이트, 말레산 무수물, 또는 4-메타크릴옥시에틸 트리멜리트산 무수물로 표면 작용화된 퀴나크리돈 안료를 제공한다. 이후에 작용기는 활성화되어 소수성 중합체와 결합하여, 안료를 소수성 중합체로 코팅시킨다. 퀴나크리돈 안료는 다양한 적용분야에 사용될 수 있다. 그들은 전기 광학 재료, 예컨대 전기영동 디스플레이에 사용을 위한 전기영동 매체에 사용하기에 충분히 적합하다. Quinacridone pigments that are surface-functionalized with glycidyl methacrylate, maleic anhydride, or 4-methacryloxyethyl trimellitic anhydride to create a functionalized pigment. The functional groups are then activated to bond hydrophobic polymers, thereby coating the pigment with the hydrophobic polymers. The quinacridone pigments can be used for a variety of applications. They are well-suited for use in electro-optic materials, such as electrophoretic media for use in electrophoretic displays.
