| 摘要 |
A light-reflecting panel is proposed, provided with a constitution wherein a fine powder-containing polyester layer comprising an aliphatic polyester series resin and a fine powder filler is layered over one face or both faces of a metal plate, as a light-reflecting material, which is thin and allows for form-processing, provided with a high degree of reflection capability while at the same time preventing a decrease in reflectance due to ultraviolet irradiation. This light-reflecting material allows excellent light reflectivity to be obtained by refractive scatter due to a difference in the refractive indices of the aliphatic polyester series resin and the fine powder filler constituting the fine powder-containing polyester layer, is characterized by almost no decrease in reflectance due to ultraviolet irradiation occurs since the aliphatic polyester series resin constituting the fine powder-containing polyester layer does not have aromatic rings that absorb ultraviolet light, and can be made into a thin type light-reflecting panel since it can be layered directly onto a metal plate without using an adhesive.
