Abstract
Official abstract text for this publication.
Provided is a double-sided pressure-sensitive adhesive tape that can express both of excellent impact resistance and excellent oil resistance. The double-sided pressure-sensitive adhesive tape includes a pressure-sensitive adhesive layer laminate obtained by laminating “n” or more pressure-sensitive adhesive layers, wherein “n” represents an integer of 2 or more, wherein each of the pressure-sensitive adhesive layers is formed from a pressure-sensitive adhesive composition, wherein the pressure-sensitive adhesive composition contains at least one kind selected from the group consisting of a monomer component (m) and a polymer component (P) obtained by polymerizing the monomer component (m), and wherein the monomer component (m) contains 50 wt % or more of butyl acrylate.
First claim
Opening claim text (preview).
What is claimed is: 1 . A double-sided pressure-sensitive adhesive tape, comprising a pressure-sensitive adhesive layer laminate obtained by laminating “n” or more pressure-sensitive adhesive layers, wherein “n” represents an integer of 2 or more, wherein each of the pressure-sensitive adhesive layers is formed from a pressure-sensitive adhesive composition, wherein the pressure-sensitive adhesive composition contains at least one kind selected from the group consisting of a monomer composition (M) containing a monomer component (m) and a polymer component (P) obtained from the monomer composition (M), and wherein the monomer component (m) contains 50 wt % or more of butyl (meth)acrylate. 2 . The double-sided pressure-sensitive adhesive tape according to claim 1 , wherein the pressure-sensitive adhesive layer laminate has (n−1) interfaces. 3 . The double-sided pressure-sensitive adhesive tape according to claim 1 , wherein the monomer component (m) contains 90 wt % to 99 wt % of the butyl (meth)acrylate. 4 . The double-sided pressure-sensitive adhesive tape according to claim 1 , wherein the monomer component (m) contains 1 wt % to 10 wt % of (meth)acrylic acid. 5 . The double-sided pressure-sensitive adhesive tape according to claim 1 , wherein the double-sided pressure-sensitive adhesive tape has a thickness of 100 μm or more.
