ABSTRACT:
A glass fiber reinforced resin laminate comprising a cured layer of glass fiber reinforced resin using an unsaturated polyester resin (I) and a surface layer of polyvinyl fluoride formed on at least one of the opposite surface of the aforementioned cured layer, wherein said unsaturated polyester resin (I) comprises (A) 40 to 80% by weight of an unsaturated polyester derived from an acid moiety containing 20 to 90 mol% of at least one member selected from the group consisting of .alpha.,.beta.-unsaturated polybasic acids and anhydrides thereof and a polyhydric alcohol moiety containing 10 to 40 mol% of diethylene glycol and (B) 60 to 20% by weight of an ethylenically unsaturated monomer containing an amount falling within the range of 0.1 to 0.6 mol, based on mol of the diethylene glycol used in the derivation of said unsaturated polyester (A), of an acrylic ester or methacrylic ester, and, on being cured, exhibits a refractive index within the range of 1.50 to 1.56 at 25.degree. C.
