An object of the present invention is to provide a pigment dispersion liquid which has excellent pigment dispersion stability and high productivity even in the case of using a fine pigment and having high pigment concentration; a method for producing the pigment dispersion liquid; a color resin composition which has excellent pigment dispersion stability, causes no clogging problem, has excellent adhesion, and is able to form color layers with high pigment concentration, with accuracy; and a color filter comprising the resin composition. Disclosed is a method for producing a pigment dispersion liquid, comprising the step of dispersing a pigment by mixing at least a pigment (A), a polymer (B) having tertiary or lower amines, an amine-reactive low molecular weight compound (C), and a dispersion medium (D), and dispersing the pigment (A) while reacting the polymer (B) with the low molecular weight compound (C), and a pigment dispersion liquid produced by the production method. |
