PIGMENT DISPERSION COMPOSITION

摘要

PURPOSE: To provide a pigment dispersion composition having a high color density (OD), excellent pigment dispersion stability and desirable for especially a black matrix. CONSTITUTION: This composition is one prepared by uniformly dispersing 100 pts.wt. pigment mixture comprising 20-80 pts.wt. carbon black pigment and 80-20 pts.wt. titanium oxide pigment, 2-20 pts.wt. dispersant and 2-20 pts.wt. solvent-soluble polymer in a solvent and can give a coating film which has a color density (OD) of 3.0 or above when its thickness is 1μm.
