<p>Disclosed is a leather-like sheet (1) having at least a base layer (11) and a skin layer (12). The skin layer (12) is composed of a crosslinked product of a polyurethane hot melt composition which contains 100 parts by mass of a urethane prepolymer (A), 5-40 parts by mass of a coloring agent (B) containing a polyol as a vehicle, 5-50 parts by mass of a polyfunctional (meth)acrylate (C), and 0.5-5 parts by mass of a photopolymerization initiator (D). The urethane prepolymer (A) is obtained by reaction 5-50% of the total number of isocyanate groups contained in an isocyanate group-containing urethane prepolymer, which is obtained by reacting apolyol (a1) containing not less than 40% by mass of a polytetramethylene glycol and a polyisocyanate (a2), with a hydroxy group-containing (meth)acrylate. The leather-like sheet (1) has excellent surface quality, while securing excellent flexibility and bending resistance.</p> |
