ANTIFOG COATING AND ANTIFOG ARTICLE

摘要

The present invention relates to an antifogging film formed on a transparent substrate. The antifogging film is characterized in that the film comprises a urethane resin having a water absorption percentage of 20-40 wt%, that the urethane resin is one derived from an acrylic polyol having an average molecular weight of 1000-4000 and a polyoxyalkylene-series polyol having an average molecular weight of 400-5000, that the film is used in an interior environment having a mechanism to forcibly remove water from the film after the water absorption saturation of the film, and that a water film is not formed upon showing antifogging property.
