<P>PROBLEM TO BE SOLVED: To provide an anti-fog coated article with an anti-fog coating film which can be used in applications such as anti-fog mirrors, windowpanes for vehicles and windowpanes for buildings, and which has high film hardness while maintaining sufficient anti-fogging performance. <P>SOLUTION: The anti-fog coated article includes a hard substrate and a water absorbent composite film that is formed on the hard substrate. The water absorbent composite film contains a polyvinyl acetal resin and 30-80 parts by mass of colloidal silica and 5-55 parts by mass of silica-equivalent particles, which are derived from a hydrolysis product or partial hydrolysis product of a silicon alkoxide compound, per 100 parts by mass of the polyvinyl acetal resin. <P>COPYRIGHT: (C)2012,JPO&INPIT |
