ABSTRACT:
The present invention provide an aqueous type pigment dispersing agent having one portion which has a high affinity with a pigment and which has at least one type of selected from the group consisting of an organic dye, anthraquinone and acridone and only at a terminal end or at both terminal ends of at least one aqueous polymer selected from an aqueous linear urethanic polymer and an aqueous linear acrylic polymer, a pigment composition using the same and a pigment dispersion. The portion having a high affinity with the pigment can be adsorbed efficiently on the surface of a pigment. At the same time, for example, a pigment, used for ink or paint can be dispersed stably due to the affinity between the polymer portion and a disperse medium to improve the adaptability in use and the quality of coating articles.
