Title:
FUNCTIONALIZED QUINACRIDONE PIGMENTS
Document Type and Number:
Japanese Patent JP2019163488
Kind Code:
A
Abstract:
To provide functionalized quinacridone pigments.SOLUTION: The invention relates to 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. The quinacridone pigments are well-suited for use in electro-optic materials, such as electrophoretic media for use in electrophoretic displays.SELECTED DRAWING: None
