  摘要：

  The problem of the present invention is to provide a pigment dispersant that shows extremely excellent properties in improving the dispersibility of pigments, and to provide a pigment dispersant that meets the need for thin film formation due to high coloring power when producing a color filter using a pigment composition or coloring composition using it, while achieving a high contrast ratio and brightness of the coating film (color filter). The above problem is solved by a pigment dispersant represented by the general formula (1). In addition, the problem is solved by a pigment dispersant in which R1 in the general formula (1) represents a hydrogen atom, an alkyl group, or an alkoxy group, R2 and R5 are hydrogen atoms, and one of R3 or R4 is a hydrogen atom while the other is a group represented by the general formula (2), the general formula (3), or the general formula (4). No selection figure is provided.
