PROBLEM TO BE SOLVED: To provide a polyurethane resin having excellent blocking resistance, water repellency, and tensile strength and elongation.SOLUTION: There is provided the polyurethane resin obtained by reacting an active hydrogen component (A) and an organic polyisocyanate component (B). The active hydrogen component (A) contains a monovalent active hydrogen compound (a1) having an aliphatic hydrocarbon group of 8 to 40 carbon atoms in an amount of 0.1 to 20 wt% based on weight of the (A). As the monovalent active hydrogen compound (a1) having an aliphatic hydrocarbon group of 8 to 40 carbon atoms, an alkane monool (a11) of 8 to 40 carbon atoms and/or an alkane monoamine (a16) of 8 to 40 carbon atoms, in particular, are preferable. As the organic polyisocyanate component (B), an aromatic polyisocyanate (b1) of 8 to 26 carbon atoms, in particular, is preferable. |
