<P>PROBLEM TO BE SOLVED: To provide a polymeric colorant containing a self-dispersion type dye/pigment as a more excellent colorant, while a pigment colorant has a restriction of chroma saturation, has such a restriction that pigment particles dispersed in a solution sometimes settle as time passes, and hence is subjected to various chemical and physical mechanisms to minimize these restrictions. <P>SOLUTION: The polymeric colorant contains a pigment having a polymer covalently bonded thereto, a dye covalently bonded to the polymer, and a dispersant covalently bonded to at least one of the polymer and the dye; and the dye covalently bonded to the polymer contains a reactant which bonds with the dye and the polymer. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
