A method of preparing submicron particles of a material, such as a pigment useful in paints or a compound useful in imaging elements, which comprises milling the agent in the presence of milling media having a mean particle size of less than about 100 microns. In a preferred embodiment, the milling media is a polymeric resin. The method provides extremely fine particles, e.g., less than 100 nm in size, free of unacceptable contamination.
