<P>PROBLEM TO BE SOLVED: To provide a hydrophilic film having dramatically improved antifogging property on a surface thereof, by treating a surface having an anionic hydrophilic group by an easy method. <P>SOLUTION: A surface having an anionic hydrophilic group of a hydrophilic film is treated with an alkaline compound to obtain a treated layer having a thickness of 0.01 to 1,000 nm. The alkaline compound is preferably an alkali metal carbonate or an alkali metal hydrogen carbonate. The alkali compound is more preferably potassium hydrogen carbonate. A method for treating a hydrophilic film comprises treating a surface having an anionic hydrophilic group with an alkaline compound solution. By treating a surface having an anionic hydrophilic group with an alkaline compound, antifogging property of the surface can be dramatically improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
