PURPOSE: To obtain the subject sheet which is low in cost, excellent in impact strength and heat ray-reflecting properties by making a sheet from an acrylic resin composition containing heat ray-reflecting particles in an acrylic resin containing a crosslinked elastomer.
CONSTITUTION: An acrylic resin (A) containing a crosslinked elastomer (B) consisting of a copolymer of (i) an alkyl acrylate and (ii) at least one kind of crosslinkable monomer selected from the group of divinylbenzene, diallyl phthalate, mono- or poly-ethylene glycol dimethacrylate, allyl methacrylate and triallyl cyanurate is impregnated with heat ray-reflecting particles (C) (preferably titanium oxide-coated mica). The resultant acrylic resin composition is shaped to a sheet preferably having a thickness of 10-300μm to afford the aimed sheet.
