Disclosed is an aqueous urethane resin composition for an artificial leather, which comprises a thermally setting aqueous urethane resin having a thermal setting temperature of 40 to 90˚C and at least one water-soluble acrylic polymer selected from the following polymers (1), (2) and (3): (1) a polymer of at least one monomer selected from the group consisting of acrylic acid, methacrylic acid and maleic acid, or an alkali metal salt and/or an amine salt of the polymer; (2) poly-α-hydroxyacrylic acid, or an alkali metal salt and/or an amine salt thereof; and (3) a polymer produced by the radical polymerization of at least one monomer selected from the group consisting of acrylic acid, methacrylic acid, maleic acid, an alkali metal salt of acrylic acid, an alkali metal salt of methacrylic acid, an alkali metal salt of maleic acid, an amine salt of acrylic acid, an amine salt of methacrylic acid and an amine salt of maleic acid and at least one member selected from the group consisting of poly-α-hydroxyacrylic acid and an alkali metal salt and/or an amine salt thereof, or an alkali metal salt and/or an amine salt of the polymer. |
