Abstract:
1. A polyurethane resin composition (W) for moisture-permeable waterproof materials, comprising a polyurethane resin, and a compound (S), wherein the polyurethane resin is obtained by reacting an active hydrogen component (A2) that comprises an oxyethylene group-containing high molecular weight diol (a1) other than the compound (S) with an organic polyisocyanate component (B), the oxyethylene group-containing high molecular weight diol (a1) has a hydroxyl value of 2 to 150 mg KOH/g, wherein the polyurethane resin and the compound (S) cannot react with each other, the compound (S) is represented by the following formula (1): wherein X 1 represents a residue produced by removing c piece(s) of active hydrogen atom(s) from an active hydrogen-containing compound having a valence of m, the c representing an integer satisfying the inequality: 1≦c≦m, the m representing an integer of 1 to 20; X X Y represents a residue produced by removing all of carboxyl groups from an aromatic polycarboxylic acid having a valence of 3 or more, wherein an aromatic ring in Y consists of carbon atoms, the carbon atoms are each optionally bound to a halogen atom and/or a substituent other than a carboxyl group, and at least one of the carbon atoms has no substituent; a represents an integer of not smaller than 1; b represents an integer of not smaller than 0; and a and b satisfy the inequality: 2≦a+b≦d−2, wherein d represents the number of hydrogen atoms bound to the carbon atoms forming the aromatic ring of the aromatic polycarboxylic acid when all of substituents including a carboxyl group in the aromatic polycarboxylic acid are substituted by hydrogen atoms.
