Abstract
There is provided a dispersion composition which has excellent dispersion stability and hardly sediments even after a long-term storage. This dispersion composition is a composition comprising a particulate material dispersed in an organic solvent, wherein a graft copolymer which has a particle diameter of 0.01-1 &mgr;m and self-disperses in said organic solvent is adsorbed to at least a part of the outer surface of said particulate material and a graft chain of said graft copolymer comprises a polysiloxane and an alkylene group of 1-18 carbon atoms.
