Antifogging article and method for manufacturing the same, water absorbing layer forming composition, and article for transportation apparatus

An antifogging article having a substrate and an antifogging film on a surface of at least a part of the substrate,

• wherein:
• the antifogging film has (i) a water absorbing layer formed on the substrate surface and comprises a water absorbing material with a saturated water absorption amount of 50 mg/cm3 or more and (ii) a base layer comprising a base material with a saturated water absorption amount of 10 mg/cm3 or less between the substrate and the water absorbing layer;
• the water absorbing material is a material comprising a first cured epoxy resin as a main body, obtained by reacting a water absorbing layer forming composition comprising a first polyepoxide component, a first polyaddition curing agent, a catalyst curing agent;
• the first polyepoxide component contained in the water absorbing layer forming composition is constituted only of at least two polyepoxides selected from aliphatic polyepoxides with mass average molecular weights of 800 to 3000;
• the water absorbing layer forming composition further comprises a silane coupling agent;
• a content of the silane coupling agent is 5 to 40 mass % relative to 100 mass % of the total mass of the first polyepoxide component, the first polyaddition curing agent, and the catalyst curing agent and
• the base material is a material whose main body is a second cured epoxy resin obtained by reacting a base layer forming composition comprising a second polyepoxide component and a second polyaddition curing agent.
