ULTRAVIOLET-TRANSMISSIBLE COMPOSITION

摘要

The invention relates to an ultraviolet-transmissible glass fiber-reinforced composition comprising (I) an unsaturated polyester resin and (II) glass fibers, said unsaturated polyester resin (I) being composed of (A) sO to 80% by weight of an unsaturated polyester prepared from an acid component consisting of 10 to 60 mole% of maleic acid or maleic anhydride and/or fumaric acid and 90 to40 mole % of another aliphatic polybasic acid and/or an alicyclic polybasic acid and an alcohol component composed of an aliphatic polyhydric alcohol and/or an alicyclic polyhydric alcohol, and (B) 50 to 20% by weight of an aromatic vinyl monomer or a mixture of it with an acrylic or methacrylic monomer as well as to a clear glass fiber-reinforced panel.
