| abstract |
The present invention is a urethane resin composition containing a urethane resin (A), water (B), and a surfactant (C) having no aromatic ring and having a hydrophobic portion having 10 or more carbon atoms. The present invention is to provide a urethane resin composition having a carbonate structure (X) and an oxyalkylene structure (Y) derived from the urethane resin (A). The present invention also provides a urethane foam sheet formed of a urethane resin composition and having a density of 200 to 1,000 kg / m 3. The urethane resin composition according to claim 1, wherein the mass ratio [X / Y] of the carbonate structure (X) to the oxyalkylene structure (Y) is in the range of 10/90 to 90/10. |
