  • Anti-fogging film-forming material, coating liquid for forming anti-fogging film, anti-fogging article, and methods for producing these
    Patent number: 9765224
    Abstract: Disclosed is an antifogging film-forming material obtained by reacting, in the presence of a quaternary ammonium salt or quaternary phosphonium salt, a copolymer represented by a certain general formula with a multifunctional epoxy compound having a solubility of 40-100 mass % in 25° C. water. The antifogging film-forming material is characterized by having a weight average molecular weight of 100,000-5,000,000. With this material, it becomes possible to obtain an antifogging article excellent in antifogging property, heat resistance, chemical resistance and abrasion resistance.
