Abstract
A water-dispersed pressure-sensitive adhesive composition includes a water-dispersible polymer and water. The viscosity X (Pa·s) and the dynamic surface tension Y (mN/m) at a life time of 100 milliseconds satisfy the following formulas (1) and (2): 0.15≤X≤1.25 (1) Y≤19.3X+35 (2)
Claims12
A water-dispersed pressure-sensitive adhesive composition comprising:
- a water-dispersible polymer, a leveling agent, a thickener, and water, wherein
- the viscosity X (Pa·s) and the dynamic surface tension Y (mN/m) at a life time of 100 milliseconds satisfy the following formulas (1) and (2):
- 0.15≤X≤1.25 (1)
- Y≤19.3X+35 (2), and
- wherein a solid content concentration of the water-dispersed pressure-sensitive adhesive composition is 10% by mass or more and 40% by mass or less, and
- a content of the thickener is 3 parts by mass or more with respect to 100 parts by mass of the water-dispersible polymer.
