Abstract

An anti-fogging tray is obtained by coating a styrenic resin sheet with an anti-fogging agent to mold a tray. The anti-fogging agent comprises 1 to 50 parts by weight of a non-ether-series hydrophilic polymer excluding a polyvinyl alcohol (e.g., a polyvinylpyrrolidone), 5 to 150 parts by weight of an ether-series hydrophilic polymer (e.g., polyoxyethylene-polyoxypropylene block copolymer, and a nonionic surfactant having an oxyethylene unit), and 1 to 50 parts by weight of a silicone oil relative to 100 parts by weight of a polyhydric alcohol fatty acid ester (e.g., a sucrose fatty acid ester, a polyglycerin fatty acid ester). A coating layer comprising a surface-treating agent may be formed on one side of the resin sheet, and a mold-releasing layer containing a component selected from the ether-series hydrophilic polymer and the silicone oil may be formed on the other side of the resin sheet.
