<p><P>PROBLEM TO BE SOLVED: To provide a sheet that is easily adhered to glass, has high transmitting property for rays, flexibility and barrier property against water vapor, and low water absorption, and is particularly suitable for a sealing material of a solar cell module. <P>SOLUTION: The sheet is made of a resin composition obtained by compounding 5 to 60 parts by mass of an aromatic monocarboxylic acid ester based on 100 parts by mass of a polyvinyl acetal resin. The aromatic monocarboxylic acid ester is preferably isodecyl benzoate, and the polyvinyl acetal resin used preferably has a polymerization degree of 400 to 3,500 and an acetalization degree of 70 to 90%. The thickness of the sheet is preferably in a range from 0.1 to 5 mm. The sheet is suitably used for a sealing material of a solar cell module. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
