  Disclosed are a production process of a dye polymer having a dye content of from 1 to 50 wt %, and the dye polymer and its use. The production process includes subjecting an addition-polymerizable monomer to living radical polymerization by using, as a polymerization initiator, a dye having a polymerization initiating group enabling the living radical polymerization. The dye polymer and a composition of the dye polymer and a pigment are useful as good coloring agents for various products or articles. The colored products or articles are high in transparency, and are provided with high added value. The dye polymer can also be used as a dispersant for pigments, thereby making it possible to afford pigment dispersions excellent in dispersion properties and dispersion stability.
