An antifogging article includes a substrate and an antifogging film covering the substrate. This antifogging film contains a water-absorbing organic polymer and an inorganic substance and has a water repellent finishing on a surface of the antifogging film. Another antifogging article includes (1) a substrate, (2) a water-absorbing, antifogging film covering the substrate, and (3) a water-permeable, protective film covering the antifogging film. This antifogging film contains (a) a polyvinyl acetal resin having a degree of acetalization of not greater than 10 mol % and (b) a hydrolysate or partial hydrolysate of an alkylsilylisocyanate represented by the general formula R<2>nSiR<1>4-n where R<1 >is an alkyl group having a carbon atom number of 1 or 2, R<2 >is an isocyanate group, and n is 1 or 2. These antifogging articles are superior in antifogging property and abrasion resistance.
