PIGMENT DISPERSION, PRODUCTION METHOD THEREOF, PHOTOSENSITIVE COLORED RESIN COMPOSITION, INKJET INK AND ELECTROPHOTOGRAPHIC PRINTING TONER CONTAINING SAID PIGMENT DISPERSION, AND COLOR FILTER

摘要

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.
