PURPOSE: A stabilizing method of a non-chrome aniline black improves physical and chemical stability of a high concentration aniline black pigment without using a harmful material such as heavy metal by using a microcapsulation process. CONSTITUTION: A stabilizing method of a non-chrome aniline black pigment includes a step of microcapsulating 100.0 parts by weight of the non-chrome-based environmental friendly aniline black pigment by using 50-200 parts by weight of one selected from a melamine resin, a benzoguamine resin, or a phenol-melamine resin and 50-200 part by weight of a maleic acid-styrene copolymer together with an outer wall-forming material. The melamine resin, benzoguamine resin, or phenol-melamine resin is an initial condensate type. |
