US Patent 7192986 Inorganic compound sol modified by organic compound

An inorganic compound sol comprises a dispersion medium and, dispersed therein, inorganic compound particulates whose surface has been modified by an organic compound exhibiting a molecular polarizability of from 2×10−40 to 850×10−40C2m2J−2. The inorganic compound sol modified by an organic compound possesses a desirable affinity with the dispersion media, providing excellent dispersion stability in solvents while avoiding aggregation of particulates.
