发明名称 ACRYLIC RESIN LAMINATED SHEET HAVING CRYSTAL-LIKE FROSTED GLASS APPEARANCE
摘要 PROBLEM TO BE SOLVED: To provide an acrylic resin laminate having a layer structure of two or more layers of a specific compsn. not damaged in its feeling even if thermal molding is performed, not generating a problem caused by a large amt. of additives and having both of the transparent feeling of a crystal glass and the profound feeling of frosted glass suppressed in the lowering of the total light permeability and effectively increased only in light diffusibility. SOLUTION: The acrylic resin layer of an acrylic resin laminated sheet is constituted of a compsn. prepared by compounding 99-70 wt.% acrylic resin and 1-30 wt.% fine spherical particles wherein the absolute value of the refractive index difference with an acrylic resin is 0.02-0.2 and an average particle size is 1-100μm. This acrylic resin layer is laminated on the single surface or both surfaces of a substrate layer comprising a compsn. prepared by compounding 0.005-1 wt.% fine spherical particles with the absolute value of the refractive index difference with the acrylic resin of 0.02-0.2 and an average particle size of 1-100μm with 99.995-99 wt.% acrylic resin.
