摘要

PURPOSE: A pigment dispersion composition is provided to have a good dispersion stability and tinting power, and also high chemical resistance, hear resistance, and light stability.;CONSTITUTION: A pigment dispersion composition comprises: (A) at least one pyridone azo group compound selected from the polymer including the monomer represented by the following chemical formula 1 and the repeating unit represented by the following chemical formula 2; (B) pigment; (C) binder resin; (D) a dispersing agent; and (E) a solvent. The above polymer has 3,000-50,000 g/mol of weight-average molecular weight and 20-200 mgKOH/g of acid value. One to eighty parts by weight of the above pyridone azo group compound is included in 100.0 parts by weight of the above pigment.;COPYRIGHT KIPO 2013
