ANTI-FOG FILM ASSEMBLIES, METHOD OF MANUFACTURE, AND ARTICLES MADE THEREOF

A repositionable and substantially transparent multi-layer anti-fog film assembly (110) comprising a film (130) and an anti-fog layer (120) formed from a polyurethane-film forming composition comprising a surfactant having an isocyanate-reactive moiety and a hydrophobic region and a hydrophilic region effective to provide the layer with anti-fog properties at temperatures that alternate between-23 °C and 65°C. Specifically, those compositions which incorporate into the polyurethane backbone a surfactant having a hydroxyl group and distinct hydrophilic and hydrophobic regions to alter surface energy as well as incorporating hydrophilic groups to increase the hydrophilicity of the polyurethane without substantially compromising its scratch resistance and chemical resistance. Optionally, an anti-fog film assembly (110) comprises an adhesive layer (140). The anti-fog film assembly (110) to be applied with any of a variety of substantially transparent substrates (390) to provide condensation-resistant articles (300) including refrigerator doors (400) and panels (490).
