PROCESS FOR PRODUCING PATTERNED SUBSTANCE

摘要

A process for producing a patterned substance, comprising pressing against a substance a template impregnated with a liquid capable of eroding or dissolving the substance to thereby transfer the pattern of the template to the substance. By this process, there can be produced optical films, such as a light diffusion film, especially a polymer film with a micropatterning exceeding diffraction limit that can be used in the production of moth-eye pattern antireflection film for which a structure of visible light wavelength or less is demanded.
