Title:
PIGMENT DISPERSION, PRODUCTION METHOD THEREOF, PHOTOSENSITIVE COLORED RESIN COMPOSITION, INKJET INK AND ELECTROPHOTOGRAPHIC PRINTING TONER CONTAINING SAID PIGMENT DISPERSION, AND COLOR FILTER
Document Type and Number:
WIPO Patent Application WO/2012/046353
Kind Code:
A1
Abstract:
The present invention provides a pigment dispersion having high productivity and excellent pigment dispersion stability even in the case of a fine pigment or a high pigment concentration, a method for producing the pigment dispersion, a colored resin composition which has excellent pigment dispersion stability, does not cause background staining, has excellent adhesive properties and can form a colored layer having a high pigment concentration with good precision, and a color filter that uses the resin composition. The present invention is a method for producing a pigment dispersion, and a pigment dispersion produced using said production method, the method being characterized by having a pigment dispersion step in which at least a pigment (A), a polymer (B) having a tertiary or lower amine, a low molecular weight compound (C) that can react with an amine, and a dispersion medium (D) are blended, and while the polymer (B) is reacted with the low molecular weight compound (C) the pigment (A) is dispersed.
