Abstract
This invention relates to a dispersant for an organic pigment comprising a compound represented by the below-described formula (1) or (2), and also to its use. According to the present invention, it is possible to provide a dispersant or the like, which can afford a coating formulation for a color filter. The coating formulation is prevented from an increase in viscosity and a reduction in storage stability even when the concentration of a pigment is high, and can fabricate the color filter with excellent transparency and color quality.
