The invention discloses a kind of antifog film formation material, it is characterized in that, it reacts the antifog film formation material obtaining for the copolymer that makes under the existence by quaternary ammonium salt or quaternary alkylphosphonium salt to be represented by specific general formula, the multi-functional epoxy compound who is 40～100 quality % with the dissolution rate of the water with respect to 25 DEG C, weight average molecular weight is 100,000～5,000,000. Utilize this material can obtain the antifog property article of antifog property, heat resistance, chemical reagent resistance and abrasion performance excellence. |
