A pigment composition in which an ester compound ordinarily used as a solvent and in other applications, such as butyl acetate or oleyl acetate, is used as a flowability improver for a pigment dispersion and which comprises a pigment and the ester compound as essential ingredients, and a pigment dispersion obtained by dispersing the pigment composition in a solvent, etc. The dispersion is significantly improved in pigment dispersibility and flowability. When the pigment composition or pigment dispersion is used in producing a color filter, a homogeneous film having high contrast can be obtained.
一种颜料组合物,其中通常用作溶剂和其他用途的酯类化合物(如醋酸丁酯或醋酸油酯)被用作颜料分散体的流动性改进剂,该颜料组合物包括作为主要成分的颜料和酯类化合物,以及通过将颜料组合物分散在溶剂等中而得到的颜料分散体。该分散体在颜料分散性和流动性方面都有明显改善。当颜料组合物或颜料分散体用于生产彩色滤光片时,可获得具有高对比度的均匀薄膜。
