Beschreibung
Zusammenfassung:	An aqueous polyurethane resin is a chain-extended product of a neutralized product of an isocyanate group-terminated prepolymer which is a reaction product of (a) an organic polyisocyanate, (b) a polyol, (c) a compound having an anionic hydrophilic group and at least two active hydrogens and (d) a polyhydric alcohol, the chain-extended product being obtained by chain-extending the neutralized product with (e) a polyamine having two or more amino groups and/or imino groups, wherein the polyol contains at least one selected from the group consisting of polycarbonate diols each having a structural unit derived from a diol having a branched structure with an integer of 3 to 10 carbon atoms and polycarbonate diols having a structural unit derived from a diol having a linear structure with an odd number of 3 to 9 carbon atoms, and the polyhydric alcohol contains a polyhydric alcohol having at least three or more active hydrogens.
