ABSTRACT:
A treated pigment and a dispersion composition thereof having preferable dispersion stability and fluidity in a dispersion medium even the pigment has no functional group reactive with a carbodiimide group on the surface thereof, and further to provide a resist composition exerting very excellent developing characteristics when forming color filters, black matrices and the like patterns. Furthermore, the invention also provides a compound for pigment treatment suited for the treatment of such pigment. A treated pigment which is producible by the treatment with a carbodiimide-based compound having at least one side chain selected from the group consisting of polyester side chains, polyether side chains and polyacrylic side chains and at least one basic nitrogen-containing group within the molecule.
