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-suitedfor use in electro-optic materials, such as electrophoretic media for use in electrophoretic displays. 为了产生官能化颜料，使用甲基丙烯酸缩水甘油酯、顺丁烯二酸酐或4-甲基丙烯酰氧基乙基偏苯三酸酐表面官能化喹吖啶酮颜料。然后活化官能团以结合疏水聚合物，从而用疏水聚合物涂布该颜料。喹吖啶酮颜料可以用于各种应用。它们非常适合用于电光材料，如用于电泳显示器的电泳介质。
