Abstract:
1. A laminated sheet comprising a front surface layer, a core layer and a back surface layer, wherein said front surface layer and said back surface layer comprise a resin composition comprising 75 to 95 mass % of a component (A) and 25 to 5 mass % of a component (B), and said core layer comprises a resin composition comprising 95 to 50 mass % of a component (C) and 5 to 50 mass % of a recycled material from the laminated sheet, wherein components (A), (B) and (C) each have a refractive index difference of at most 0.05; wherein component (A) is a rubber modified styrenic copolymer comprising a (meth)acrylic acid ester monomer and a styrenic monomer, which comprises 5 to 25 mass % of butadiene, the copolymer comprising a matrix resin (A-1) and a grafted rubber (A-2), wherein the grafted rubber (A-2) has a graft ratio of 30 to 50% and a grafted rubber particle size of 0.1 to 0.5μm; wherein component (B) is a polyether ester amide; wherein component (C) is a rubber modified styrenic copolymer comprising a (meth)acrylic acid ester monomer and a styrenic monomer, which comprises 5 to 15 mass % of butadiene, the copolymer comprising a matrix resin (C-1) and a grafted rubber (C-2), wherein the grafted rubber (C-2) has a graft ratio of 70 to 90% and a grafted rubber particle size of 0.4 to 1.0 μm.
