<P>PROBLEM TO BE SOLVED: To provide an anti-fogging sheet having a coating film that exhibits excellent water resistance as well as excellent anti-fogging properties. <P>SOLUTION: The anti-fogging sheet is constituted by laminating a first layer and a second layer on a substrate, in that order. The first layer is configured from the product obtained by heat-treating a first coating composition, which contains a water-absorbent resin. The second layer is configured from the product obtained by heat-treating a second coating composition, which contains a polyol. The water-absorbent resin preferably contains a polyvinyl alcohol and a polyacrylic acids. The polyol preferably contains polyethylene glycol. At least one of the first coating composition and the second coating composition preferably contains at least one compound selected from metal alkoxides, metal alkoxide hydrolysates, and metal alkoxide hydrolytic polycondensates. <P>COPYRIGHT: (C)2011,JPO&INPIT |
