LAMINATED SHEET, FOAMED LAMINATED SHEET, AND METHOD FOR PRODUCING FOAMED LAMINATED SHEET
PROBLEM TO BE SOLVED: To provide a laminated sheet, a foamed laminated sheet and a method for producing a foamed laminated sheet where discoloration due to starch and the like can be prevented.SOLUTION: In a laminated sheet (stock roll for wall paper) 1 according to one embodiment, on a base material 2, a foaming agent-containing resin layer 4 containing a foaming agent, and a discoloration prevention functional layer 7 are laminated in the stated order, where the discoloration prevention functional layer is disposed on the outermost surface layer and contains an enzyme inhibitor at least containing cations with each ion radius of 67 pm or more and 95 pm or less.SELECTED DRAWING: Figure 1
【課題】本発明は、澱粉等に起因する変色を抑制可能な積層シート、発泡積層シート及び発泡積層シートの製造方法を提供可能とすることを目的とする。【解決手段】本発明の一態様に係る積層シート（壁紙用原反）１では、基材２上に、発泡剤を含有する発泡剤含有樹脂層４と、最表層に配置され、イオン半径が６７ｐｍ以上９５ｐｍ以下の陽イオンを少なくとも含む酵素阻害剤を含有する変色防止機能層７とがこの順に積層されている構成とした。【選択図】図１
