| titleOfInvention | Adhesive sheet |
| abstract | The present invention provides a means capable of reducing the amount of tackifier used in the entire pressure-sensitive adhesive layer while ensuring high adhesion performance to low-polarity adherends. A pressure-sensitive adhesive sheet having a substrate, a first pressure-sensitive adhesive layer and a second pressure-sensitive adhesive layer in this order, wherein the first pressure-sensitive adhesive layer comprises a first pressure-sensitive adhesive layer containing a first acrylic polymer. 1, the second pressure-sensitive adhesive layer is formed from a second pressure-sensitive adhesive composition containing a second acrylic polymer and a tackifier, and the first pressure-sensitive adhesive composition The content concentration (% by mass) of the tackifier for the first acrylic polymer contained in the product is the concentration of the tackifier for the second acrylic polymer contained in the second pressure-sensitive adhesive composition. Less than the content concentration (% by mass), the content mass of the structural unit derived from 2-ethylhexyl (meth)acrylate in the first acrylic polymer is less than (meth) in the second acrylic polymer A pressure-sensitive adhesive sheet containing less than the mass of structural units derived from 2-ethylhexyl acrylate. [Selection figure] None |
