<p><P>PROBLEM TO BE SOLVED: To provide a transparent laminated plate which can maintain high transparency and also secure high glass transition temperature. <P>SOLUTION: The transparent laminated plate is formed by impregnating a glass-fiber substrate with a resin composition having a refractive index close to that of the glass fiber which has been prepared by mixing a high refractive index resin having a refractive index higher than that of a glass fiber, and a low refractive index resin having a refractive index lower than that of the glass fiber, and then curing the resin composition, characterized in that a cyanate ester resin is used as the high refractive index resin. By using a cyanate ester resin as the high refractive index resin, high transparency can be maintained together with a high glass transition temperature. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
