Artificial leather for water-based urethane resin composition, method of manufacturing artificial leather, and artificial leather

摘要

And contains a heat-sensitive coagulation water-based urethane resin is 40~90 ℃ the heat-sensitive coagulation temperature, and a water-soluble acrylic polymer (1), (2), is at least one of the polymer (3) below artificial leather for water-based urethane resin composition to be. Polymers of one monomer, amine salts and / or alkali metal of the polymer is at least selected from the group consisting of (1) acrylic acid, maleic acid and methacrylic acid. (2) poly -α- hydroxy acrylic acid, amine salt and alkali metal or its /. Alkali metal salt (3) acrylic acid, methacrylic acid, maleic acid, acrylic acid, alkali metal salts of methacrylic acid, alkali metal salts of maleic acid, amine salt of acrylic acid, amine salt of maleic acid and amine salt of methacrylic acid and one monomer, polymer obtained by radical polymerization and at least one selected from the group consisting of amine salts and their alkali metal and / or poly -α- hydroxy acrylate is at least selected from the group consisting of , amine salts and / or alkali metal of the polymer.
