Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a building laminate and a daylighting system, which have high light reflection, high light scattering properties, and high weather resistance.SOLUTION: A building laminate according to this invention comprises: a reflection base material with visible light reflectivity; and a light reflection layer and a light scattering layer that are laminated on one surface of the reflection base material. The light reflection layer is a layer having a particle size showing Mie scattering property and containing a metal oxide white pigment that can absorb ultraviolet light. The light scattering layer is a layer containing fine particles with the particle size showing geometric scattering property. The above purpose is achieved by providing the building laminate.SELECTED DRAWING: Figure 1 【課題】本発明は、高光反射性能、高光散乱性能および高耐候性能を有する建材用積層体および採光システムを提供することを主目的とする。【解決手段】本発明は、可視光線に対して反射性を有する反射基材と、上記反射基材の一方の表面上に積層された光反射層および光散乱層と、を有する建材用積層体であって、上記光反射層は、ミー散乱性を示す粒子径を有し、かつ、紫外線を吸収可能な金属酸化物白色顔料を含有する層であり、上記光散乱層は、幾何散乱性を示す粒子径を有する微粒子を含有する層であることを特徴とする建材用積層体を提供することにより、上記目的を達成する。【選択図】図１
