PIGMENT DISPERSING AGENT FOR MANUFACTURING DISPERSED PIGMENT MATERIALS WITH SUPERIOR MOBILITY AND STORAGE STABILITY AND AQUEOUS DISPERSED PIGMENTS INCLUDING THE SAME

摘要

PURPOSE: A pigment dispersing agent is provided to be more economical than the dispersion of surface-processing pigment, to obtain excellent dispersion stability, and to improve printability and the storage stability of aqueous dispersed pigments.;CONSTITUTION: A pigment dispersing agent is a compound which is marked by chemical formula 1. The chemical formula 1 is Ar-X-(CH2CH2)n-OH. In chemical formula 1, Ar shows an aromatic group of C6 ~ C20, X indicates a bond, O, CH2COO, N(CH2CH2)NOH, or NH, and n indicates an integer of 5~30. Ar is an aromatic group which is selected from a phenyl group, biphenyl group, 2,2- diphenylpropane group, naphthalene group, carbazole group, and fluoren group.;COPYRIGHT KIPO 2010
