摘要

Synthetic resin panel consisting of a core layer (1) of polycarbonate resin covered on at least one of its outer sides by a storage layer (2) containing between 5 and 15% by weight of an UV absorber, and on that side of said storage layer facing away from said core layer, by a cover layer (3) of synthetic resin containing an UV absorber, wherein said UV absorber, incorporated in said cover layer (3), different from said UV absorber incorporated in said storage layer (2), is of low volatility and is present at a concentration exceeding 2% by weight.
