Zusammenfassung:	A dispersion, a composition containing the dispersion, and a coating or film obtained by coating the composition on a substrate are provided to prevent the deterioration of fluidity due to the large content of a dispersant. A dispersion comprises a nanoparticle or a particle; at least one polyisobutenyl succinic anhydride(PIBSA) or a PIBSA reaction product; and optionally at least one member selected from the group consisting of toluene, xylene, mineral spirits, hexane and phenoxy isopropanol. Preferably the PIBSA is represented by the formula. A composition comprises the dispersion; and at least one matrix polymer selected from the group consisting of polyacrylate, polysiloxane, polyurethane, polyester, polyamide, poly(vinyl chloride), polyepoxide and polyalkyd. Preferably the particle is at least one metal oxide of zinc, zirconium, cerium, titanium, aluminum, indium and tin.
