<p><P>PROBLEM TO BE SOLVED: To provide a transparent film which is more excellent in optical characteristic and appearance quality than a conventional one. <P>SOLUTION: This transparent film is formed by impregnating a transparent resin composition into a glass fiber substrate, and by curing it. In the glass fiber, the content of boron oxide (B<SB POS="POST">2</SB>O<SB POS="POST">3</SB>) is 12-22 mass%, the content of magnesium oxide (MgO) is 2-12 mass%, the content of aluminum oxide (Al<SB POS="POST">2</SB>O<SB POS="POST">3</SB>) is 7-17 mass%, the content of silicon dioxide (SiO<SB POS="POST">2</SB>) is 45-55 mass%, the content of calcium oxide (CaO) is≤10 mass%, the content of strontium oxide (SrO) is≤5 mass%, and the content of barium oxide (BaO) is≤10 mass%. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
