摘要： This invention relates to a method of producing antifog sheet of a thick film type having a thickness of at least 30 mu m. The method comprises preparing a composition consisting of a polymer, a hydrophilic monomer and a surfactant as the essential components, having a viscosity of up to 50,000 cP but not containing a solvent, applying the composition to the surface of a support film without using any solvent, and causing cross-linkage of the applied composition by irradiation with ionizing radiation to prepare a hydrophilic film which is at least 30 mu m thick.
