摘要：A transparent film has a high glass transition temperature, yet retaining high transparency. The transparent film includes a glass fiber substrate impregnated with a resin composition in which a high refractive resin having refractive index higher than the glass fiber is mixed with a low refractive resin having refractive index lower than the glass fiber to have resultant refractive index approximate to that of the glass fiber when cured. The high refractive resin includes a cyanate-ester resin so as to increase a glass transition temperature, yet retaining high transparency.

主权项：1. A transparent film comprising: a glass fiber substrate made of glass fibers and impregnated with a resin composition in which a high refractive resin having refractive index higher than the glass fiber is mixed with a low refractive resin having a refractive index lower than said glass fiber to have a resultant refractive index approximate to that of said glass fiber when cured, wherein: said high refractive resin includes a cyanate-ester resin, said low refractive resin includes an epoxy resin including 1,2-epoxy-4-(2-oxiranyl)cyclohexane, said resin composition includes a curing initiator of zinc octanoate, and said cyanate-ester resin is 2,2-bis(4-cyanatephenyl)propane.
