    • PURPOSE: Pigment dispersion liquid is provided to reduce the addition amount of a dispersing agent, a pigment derivative, and a resin without the loss of an optical performance and storage stability and to facilitate the color performance, development and pattern characteristics. CONSTITUTION: Surface-modified polyurethane is obtained by modifying the surface of polyurethane with free isocyanate groups introduced by a sulfonated polyethylene oxide. The sulfonated polyethylene oxide is a sulfonated polyethylene oxide one side of which is sulfonated. An isocyanate group is introduced to the other side of the sulfonated polyethylene oxide. The sulfur content of the surface-modified polyurethane is 50 % or greater in comparison with a theoretical value. The pigment dispersion liquid includes a pigment, a dispersant, a dispersion solvent, and the surface-modified polyurethane.
