(57) [PROBLEMS] To provide a recording medium liquid having excellent dispersibility of a colorant component and long-term storage stability, and having excellent density, sharpness, water resistance and light resistance of a formed image. A recording medium liquid containing a liquid medium used in an inkjet recording method and a colorant component, wherein the colorant component has a segment (A) having a reactive group capable of reacting with a functional group on the pigment surface. ) And a polymer having a segment (B) having substantially no reactive group and having a higher affinity for a liquid medium than the segment (A), the pigment being grafted to the pigment. A recording medium liquid containing a composite polymer. |
