| 摘要 |
An object of the present invention is to provide a foamed laminate sheet that has practical surface strength and excellent background following properties even when an olefin-based resin is used as a resin component of a foamed resin layer, and a laminate sheet (unfoamed material) useful for producing the foamed laminate sheet. A laminate sheet comprising at least a foaming-agent-containing resin layer on a substrate,
(1) the foaming-agent-containing resin layer comprising an ethylene copolymer, and an olefin copolymer comprising at least an ±,² unsaturated carboxylic acid anhydride as a constituent monomer,
(2) the ethylene copolymer being at least one member selected from the group consisting of ethylene-±,² unsaturated carboxylic acid ester copolymers and ethylene-carboxylic acid vinyl ester copolymers, and
(3) the foaming-agent-containing resin layer being crosslinked. |
