Pigment dispersions for color filters are composed of pigments, dispersants, film-forming resins and liquid media. The dispersants comprises compounds represented by the following formula (I):
wherein X and X' each independently represent H, OH, alkoxy, primary, secondary or tertiary amino, or acylamino; Y represents an anthraquinonylamino, phenylamino or phenoxy group having H, OH, alkoxy, primary, secondary or tertiary amino, or acylamino at the 4-position or 5-position; A and B each independently represent alkyl, cycloalkyl or aryl, and at least one of A and B has at least one substituent group containing a basic nitrogen atom; and Z represents H, CN, halogen, alkyl, alkoxy, NO2, benzoylamino or 3-benzoyl, and the 3-benzoyl group may be fused together with X to form an acridone ring. These pigment dispersions are useful for the production of color filters.
滤色片用颜料分散体由颜料、分散剂、成膜树脂和液体介质组成。分散剂包括下式 (I) 所代表的化合物:
其中 X 和 X'各自独立地代表 H、OH、烷氧基、伯氨基、仲氨基或叔氨基或酰氨基;Y 代表在 4 位或 5 位上具有 H、OH、烷氧基、伯氨基、仲氨基或叔氨基或酰氨基的蒽醌基氨基、苯基氨基或苯氧基;A 和 B 各自独立地代表烷基、环烷基或芳基,且 A 和 B 中至少有一个取代基含有碱基氮原子;Z 代表 H、CN、卤素、烷基、烷氧基、NO2、苯甲酰氨基或 3-苯甲酰基,3-苯甲酰基可与 X 融合在一起形成吖啶酮环。这些颜料分散体可用于生产彩色滤光片。
