Dispersion composition and method for producing the same

摘要

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