  • Publication number: 20230364893
    Abstract: There is provided a laminate having excellent resistance to print removal and excellent abrasion resistance required in BS5609:1986 and also providing the excellent ink dryness. The laminate includes a substrate layer (A) and a formed resin layer (B) including a first porous sub-layer (B1) and a second porous sub-layer (B2). The substrate layer (A), the second porous sub-layer (B2), and the first porous sub-layer (B1) are laminated in this order. The first porous sub-layer (B1) contains a propylene-based polymer (d1), an ethylene-based polymer (PE resin) or acrylonitrile-butadiene-styrene copolymer (ABS resin), and a filler (e1). The second porous sub-layer (B2) contains a propylene-based polymer (d2) and a filler (e2), and is free of a PE resin and an ABS resin. The content of the filler (e1) or (e2) in each porous sub-layer is 50 to 75 mass%.
