- the obtained prepolymer composition was added to 550 g of ion-exchanged water in which 0.2 mol of SE-21 was dissolved, and stirred at room temperature for 30 minutes. Subsequently, 0.22 mol of ethylenediamine diluted with 80 g of water was added, and the mixture was stirred at room temperature for 30 minutes to obtain an objective water-dispersed polyurethane composition No. 4.
- the resulting water-dispersed polyurethane composition No. 4 had a urethane bond concentration of 1.49 eqZkg, an average molecular weight of 2800, and a solid content of 39.2%.
- Example 2 Except that a polyester polyol having a number average molecular weight of 2000 obtained from 3-methyl-1,5-pentanediol and adipic acid was used in place of the both-end hydroxyl group type butyl ether compound, the above Example 2 and A water-dispersed polyurethane composition No. 5 was obtained by the same composition and method.
- the obtained water-dispersed polyurethane composition No. 5 had a urethane bond concentration of 1.28 eq / kg, an average molecular weight of 2850, and a solid content of 43.5%.
- Example 4 Except that a polyester polyol having a number average molecular weight of 2000 obtained from 3-methyl-1,5-pentanediol and adipic acid was used in place of the both-end hydroxyl group type butyl ether compound, Example 4 and A water-dispersed polyurethane composition No. 6 was obtained by the same composition and method.
- the resulting water-dispersed polyurethane composition No. 6 had a urethane bond concentration of 1.28 eq / kg, an average molecular weight of 2850, and a solid content of 39.7%.
- a water-dispersed polyurethane composition was coated on a corona discharge-treated stretched polypropylene film using a bar coater, and heated at 50 ° C. for 30 minutes to obtain a test piece having an ink surface that also had a polyurethane composition strength.
- the test piece was bent at 180 ° C. with the ink surface facing outward. 18mm wide cellophane tape is pressed against the ink surface of the bent part of the test piece and forcedly peeled to observe the adhesion of the ink. The result was rated as 1, and was evaluated on a five-point scale.
- a water-dispersed polyurethane composition was applied onto a corona discharge-treated stretched polypropylene film using a bar coater. After drying at 25 ° C for 24 hours, observe the dry state of the coated surface by touching it.Assuming that the fingerprint remains on the coated surface is 5, and the water-dispersed polyurethane composition is 1 , Evaluated in 5 stages.
- a water-dispersed polyurethane composition was applied onto a corona discharge-treated stretched polypropylene film using a bar coater. After drying by heating at 50 ° C for 30 minutes, a load of 0.5 kgZcm 2 was applied with the coated surfaces in close contact with each other, and the mixture was left at a temperature of 40 ° C. After 24 hours from the start of standing, the blocking property of the part where the coated surfaces were bonded together was observed. ⁇ indicates that there was no blocking property, ⁇ indicates that there was a slight blocking property, and X indicates that there was blocking property. evaluated.
- the water-dispersed polyurethane composition of the present invention is excellent in adhesion, tack and blocking resistance.
