发明名称 Coloring composition for color filters containing microencapsulated pigment composed of polyhydroxyalkanoate
摘要 The invention provides coloring composition for color filters making use of a pigment, in which the dispersed state of the pigment is stable without using any surfactant, and so aggregation is hard to occur, and which permits formation of high-definition and high-quality images excellent in color rendition, transparency and contrast, and a simple production process thereof, by which the use of surfactants can be abolished, or the amount of surfactants used can be reduced to a great extent. The coloring composition for color filters is provided by using at least a coloring material obtained by coating at least part of surfaces of pigment particles with polyhydroxyalkanoate, and a dispersion medium for the coloring material.
