Abstract
An object of the present invention is to provide a colored liquid with superior separability from polar solvents for use with an electrowetting or electrofluidic device that uses a coloring agent added as a colorant to a nonpolar solvent. A colored liquid according to the present invention contains a nonpolar solvent and a colorant, and the colorant is a modified pigment containing a pigment (A) and a polymer (P) formed on a surface thereof by polymerizing a polymer (B) soluble in a nonaqueous solvent and at least one polymerizable unsaturated monomer (C) that is soluble in the nonaqueous solvent and that becomes insoluble or poorly soluble in the nonaqueous solvent after polymerization. A multi-phase liquid colored composition according to the present invention contains the colored liquid and a polar solvent immiscible with the colored liquid.
