PROBLEM TO BE SOLVED: To provide an antifogging composition that is one-pack coating type, forming hardened coating layers under photoirradiation of low energy and gives long-term retention of excellent antifogging properties. SOLUTION: This antifogging composition comprises (a) a urethane polymer with an average molecular weight of 2,000-20,000, (b) a diacrylate bearing a cyclic structure, (c) a polyalkylene glycol acrylate, (d) an alkylpolyol polyacrylate and (e) a photosetting catalyst.
