| description | PROBLEM TO BE SOLVED: To provide a method for producing a pigment dispersion for color filters, obtaining a cured film excellent in contrast and low viscosity, and a colored composition for color filters, containing the pigment dispersion, obtained by the method.SOLUTION: The method for manufacturing a pigment dispersion for color filters, includes a step (1) of mixing (A) a polymer dispersant comprising a component unit originating from (meth)acrylates and an amido group and having an amine value of 1 mgKOH/g or less with (B) organic pigments in an ester-based organic solvent (C), and a step (2) of adding and dispersing tetraalkylammonium salt (D). |
