| description | The invention provides an antifogging article comprising a transparent substrate and an antifogging film having a base layer and a water absorbing layer on a surface of at least a part of the transparent substrate, the base layer and the water absorbing layer being formed on the surface in this order from the transparent substrate, wherein the water absorbing layer is made of a water absorbing material and formed from a water absorbing layer forming composition to have wet spreading capability, without unevenness and wrinkle, the water absorbing material containing a first cured epoxy resin as a main body, and having a saturated water absorption amount of 50 mg/cm 3 or more, the base layer is made of a base material and formed from a base layer forming composition, the base material has a lower saturated water absorption amount than the saturated water absorption amount of the water absorbing material, at least one of the water absorbing layer forming composition and the base layer forming composition contains an ultraviolet absorbent comprising at least one selected from the group consisting of a benzophenone-based compound, a triazine-based compound, and a benzotriazole-based compound, and a change of haze (”H(%)) of the antifogging article before and after an exposure test consisting of holding the antifogging film surface above a hot water bath of 40°C for 35 minutes and thereafter drying it by air, is 2.5% or less. |
