透明又は半透明の熱可塑性フィルム層、装飾層および支持基材層がこの順に積層された熱成形用積層シートであって、該支持基材層が３層のポリオレフィン系樹脂層の積層からなり、該３層が、
１）無機フィラーを含有しないか、含有する無機フィラーの平均粒子径が４μｍ以下である装飾層に隣接する層（層Ａ）と、
２）無機フィラーの含有率が、層Ａの無機フィラー含有率に対して±１０質量％以内である層（層Ｃ）と、
３）層Ａと層Ｃに挟まれた層（層Ｂ）の３層
であり、層Ａ、層Ｂ及び層Ｃの無機フィラー含有率合計が５〜６０質量％である熱成形用積層シート。 A laminated sheet for thermoforming in which a transparent or translucent thermoplastic film layer, a decorative layer, and a supporting base material layer are laminated in this order, the supporting base material layer comprising a laminate of three polyolefin resin layers, The three layers are
1) a layer (layer A) that does not contain an inorganic filler or is adjacent to a decorative layer having an average particle size of 4 μm or less of the inorganic filler contained;
2) a layer (layer C) in which the content of the inorganic filler is within ± 10% by mass with respect to the inorganic filler content of the layer A;
3) A laminated sheet for thermoforming that is a three-layer (layer B) sandwiched between layers A and C, and the total inorganic filler content of layers A, B, and C is 5 to 60% by mass. 前記熱可塑性フィルム層と前記支持基材層との成形工程における成形収縮率の差が０．５％以内である請求項１に記載の熱成形用積層シート。 The laminated sheet for thermoforming according to claim 1, wherein a difference in molding shrinkage in the molding step between the thermoplastic film layer and the support base material layer is within 0.5%. 前記層Ａと層Ｃとの成形収縮率の差が０．５％以内である請求項１または２に記載の熱成形用積層シート。 The laminated sheet for thermoforming according to claim 1 or 2, wherein a difference in molding shrinkage between the layer A and the layer C is within 0.5%. 前記層Ａと層Ｃが、同じポリオレフィン系樹脂を使用し且つ無機フィラーの含有率が同じである請求項１〜３のいずれかに記載の熱成形用積層シート。 The layered sheet for thermoforming according to any one of claims 1 to 3, wherein the layer A and the layer C use the same polyolefin-based resin and have the same content of the inorganic filler. 前記装飾層が、鏡面状金属光沢を有する金属蒸着層またはインキ層である請求項１〜４のいずれかに記載の熱成形用積層シート。 The laminated sheet for thermoforming according to any one of claims 1 to 4, wherein the decorative layer is a metal vapor-deposited layer or an ink layer having a mirror-like metallic luster. 前記鏡面状金属光沢を有するインキ層に用いられるインキが金属薄膜細片を含有するインキである請求項５に記載の熱成形用積層シート。 The laminated sheet for thermoforming according to claim 5, wherein the ink used for the ink layer having a mirror-like metallic luster is an ink containing metal thin film strips.
