Title:
PIGMENT DISPERSION COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2010/101210
Kind Code:
A1
Abstract:
Provided is a pigment dispersion composition capable of creating a color filter with a high contrast. The color filter rarely undergoes surface roughening during the processing steps thereof such as development, post-baking, and UV cleaning, and thus can attain excellent display performance. Further, the pigment dispersion composition exhibits high dispersion stability. A pigment dispersion composition which comprises both organic pigment fine particles and a high-molecular compound having pigment-adsorbing groups, wherein the organic pigment fine particles are build-up pigment fine particles which are prepared by a precipitation process of mixing a solution of an organic pigment in a good solvent with a poor solvent which is compatible with the good solvent and acts as a poor solvent for the organic pigment.
