摘要： A laminated resin sheet comprising (A) a laminated base material composed of (A.sup.1) an expanded resin layer and (A.sup.2) a non-expanded resin layer obtained by co-extrusion of (a.sup.1) a blowing agent-containing thermoplastic resin and (a.sup.2) a filler-containing thermoplastic resin containing 9 to 80% by weight of a filler through a T die, having laminated on at least one side thereof (B) synthetic paper comprising a stretched porous thermoplastic resin film containing an inorganic filler. The laminated resin sheet is light and highly rigid and exhibits a beautiful appearance with satisfactory printability and is therefore useful as various display materials and thermoformable sheeting for food trays, etc.
