PIGMENT DERIVATIVE COMPOUND CAPABLE OF SECURING THE HIGH COLORING STRENGTH WHEN USING AS AN ASSISTANT INGREDIENT FOR A PIGMENT COMPOSITION OF A COLOR FILTER, THE PIGMENT COMPOSITION CONTAINING THEREOF, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A pigment derivative compound, a pigment composition containing thereof, and a manufacturing method thereof are provided to secure the excellent viscosity and dispersion stability of the compound when being applied to the pigment composition.;CONSTITUTION: A pigment derivative compound contains a mother material pigment, a sulfonic acid group or a phosphoric acid group, and a polyalkylene glycol diamine group ionic combined with the sulfonic acid group or the phosphoric acid group. A manufacturing method of the pigment derivative compound comprises the following steps: reacting the mother material pigment with the sulfonic acid or the phosphoric acid; and reacting the mother material pigment applied with a sulfonic acid group or a phosphoric acid group with a polyalkylene glycol diamine compound.;COPYRIGHT KIPO 2011
