<p><P>PROBLEM TO BE SOLVED: To provide transparent styrene resin anti-fogging sheets with practically improved anti-fogging property. <P>SOLUTION: Styrene resin sheets coated at least on one side with an anti- fogging composition comprising 80-99 wt.% of a nonionic surfactant composition composed of (A) 30-95 parts by mass of a nonionic surfactant with an HLB of 12-18 and surface tension of 30-39 mN/m at 0.1 wt.% aqueous solution and at 25°C and (B) 70-5 parts by mass of a nonionic surfactant with a surface tension of 40-60 mN/m at 0.1 wt.% aqueous solution and at 25°C, and 20-1 wt.% of polyvinyl alcohol, and the contact angle of one surface of the sheet coated with the anti-fogging composition with water is in the range of 1-15°. <P>COPYRIGHT: (C)2003,JPO</p> |
