    摘要: A leather-like sheet is provided having a substrate layer and a surface skin layer in which the surface skin layer is composed of a cross-linked product of a polyurethane hot-melt composition containing 100 parts by mass of a urethane prepolymer, 5 parts by mass to 40 parts by mass of a coloring agent containing a polyol, 5 parts by mass to 50 parts by mass of multi-functional (meth)acrylate, and 0.5 parts by mass to 5 parts by mass of a photopolymerization initiator, wherein the urethane prepolymer can be obtained by reacting 5% to 50% of the number of isocyanate groups in a urethane prepolymer containing isocyanate groups that is obtained by reacting a polyol containing 40% by mass or more of polytetramethylene glycol and a polyisocyanate with a (meth)acrylate containing a hydroxyl group. This leather-like sheet has an excellent surface grade while maintaining excellent suppleness and bending resistance.

    摘要: There are provided a moisture-curable polyurethane hot melt adhesive containing a urethane prepolymer obtained by reacting a polyol (A) with a polyisocyanate (B), wherein the polyol (A) contains 40 to 80 mass % of a polycarbonate polyol (a1), 5 to 40 mass % of polytetramethylene glycol (a2), and 5 to 40 mass % of a polyester polyol (a3) obtained by reacting a polycarboxylic acid containing an aliphatic polycarboxylic acid and an aromatic polycarboxylic acid with a polyether polyol obtained by adding an alkylene oxide to bisphenol A, based on the total amount of the polyol (A), and a multilayer sheet using this adhesive. This adhesive can maintain excellent adhesion strength even after washing is repeatedly performed under stringent washing conditions without impairing soft texture of a multilayer sheet.
