titleOfInvention | Method for producing pigment dispersion for color filter |
abstract | A method for producing a pigment dispersion for a color filter capable of forming a cured film excellent in contrast and developability, and a coloring composition for a color filter containing the pigment dispersion obtained by the method. [1] An organic pigment, an ester organic solvent, a graft polymer (A) containing a constitutional unit derived from vinylpyrrolidone in the main chain and a constitutional unit derived from (meth) acrylate in the side chain, And a step (1) of obtaining a dispersion by dispersing a mixture containing a polyamine-based dispersant (B) having an acid value of 10 to 30 mg KOH / g and an amine value of 5 to 50 mg KOH / g, and from the obtained dispersion, A method for producing a pigment dispersion comprising the step (2) of removing at least a part of the graft polymer (A) and the polyamine dispersant (B) not adsorbed on the organic pigment to obtain a pigment dispersion, wherein the weight ratio [[(A) + (B)] / organic pigment] is 0.7 to 1.3 in step (1) and 0.2 to 0.5 in step (2). Dispersion production method and [2 Wherein a coloring composition for color filter containing the pigment dispersion obtained by the process. [Selection figure] None |
