Abstract

The present invention provides an urethane resin composition containing an urethane resin (A), water (B), and a film forming auxiliary (C), wherein the film forming auxiliary (C) is a polyethylene glycol (c1) and/or a polyethylene glycol (c2) having an alkoxy group having 11 or less carbon atoms. Further, the present invention provides a layered product having at least a substrate (i) and a foamed layer (ii) which is formed from the above-mentioned urethane resin composition. The polyethylene glycol (c1) and the polyethylene glycol (c2) preferably have a weight average molecular weight in the range of from 100 to 4,000. The urethane resin (A) preferably has an anionic group.

First claim

The invention claimed is:

1. A urethane resin composition containing a urethane resin (A), water (B), and a film forming auxiliary (C), wherein the film forming auxiliary (C) is a polyethylene glycol (c1) and/or a polyethylene glycol (c2) having an alkoxy group having 11 or less carbon atoms; and wherein the film forming auxiliary (C) is present in a range of from 0.05 to 50 parts by mass relative to 100 parts by mass of the urethane resin (A).

2. The urethane resin composition according to claim 1 , wherein the polyethylene glycol (c1) and the polyethylene glycol (c2) have a weight average molecular weight in the range of from 100 to 4,000.

3. The urethane resin composition according to claim 1 , wherein the urethane resin (A) has an anionic group.

4. The urethane resin composition according to claim 1 , further containing a surfactant (D) having a hydrophobic portion having 10 or more carbon atoms.

5. The urethane resin composition according to claim 4 , wherein the surfactant (D) is a stearic acid salt.

6. A layered product having at least a substrate (i) and a foamed layer (ii) which is formed from the urethane resin composition according to claim 1 .

7. The layered product according to claim 6 , wherein the foamed layer (ii) is formed by mechanically foaming the urethane resin composition.

8. The urethane resin composition according to claim 2 , wherein the urethane resin (A) has an anionic group.

9. The urethane resin composition according to claim 2 , further containing a surfactant (D) having a hydrophobic portion having 10 or more carbon atoms.

10. The urethane resin composition according to claim 3 , further containing a surfactant (D) having a hydrophobic portion having 10 or more carbon atoms.

11. The urethane resin composition according to claim 8 , further containing a surfactant (D) having a hydrophobic portion having 10 or more carbon atoms.

12. The urethane resin composition according to claim 9 , wherein the surfactant (D) is a stearic acid salt.

13. The urethane resin composition according to claim 10 , wherein the surfactant (D) is a stearic acid salt.

14. The urethane resin composition according to claim 11 , wherein the surfactant (D) is a stearic acid salt.

15. A layered product having at least a substrate (i) and a foamed layer (ii) which is formed from the urethane resin composition according to claim 2 .

16. A layered product having at least a substrate (i) and a foamed layer (ii) which is formed from the urethane resin composition according to claim 3 .

17. A layered product having at least a substrate (i) and a foamed layer (ii) which is formed from the urethane resin composition according to claim 4 .

18. A layered product having at least a substrate (i) and a foamed layer (ii) which is formed from the urethane resin composition according to claim 5 .

19. A layered product having at least a substrate (i) and a foamed layer (ii) which is formed from the urethane resin composition according to claim 8 .

20. A layered product having at least a substrate (i) and a foamed layer (ii) which is formed from the urethane resin composition according to claim 9 .
