ADHESIVE SHEET
The disclosed adhesive sheet that exhibits high anchoring performance and where separation between the substrate and the adhesive layer substantially does not occur when unwinding or re-peeling in actual applications. The adhesive sheet comprises a substrate including a heteroatom-containing polymer component at least at a portion of a surface a silicone adhesive layer that is in contact with the heteroatom-containing polymer component, wherein the heteroatom-containing polymer having, at a side chain, an N,N-substituted amino group or a heterocyclic group.
1 . An adhesive sheet comprising:
a substrate including a heteroatom-containing polymer component at least at a portion of a surface; and
a silicone adhesive layer in contact with the heteroatom-containing polymer component;
the heteroatom-containing polymer having, at a side chain, an N,N-substituted amino group or a heterocyclic group.
2 . The adhesive sheet according to claim 1 , wherein the heterocyclic group has a nitrogen atom as a heteroatom.
3 . The adhesive sheet according to claim 1 , wherein a layer of the heteroatom-containing polymer component is formed on the substrate.
4 . The adhesive sheet according to claim 1 , wherein the heteroatom-containing polymer component is present on the surface of the substrate and internally.
5 . The adhesive sheet according to claim 1 , wherein the substrate is a fabric.
6 . The adhesive sheet according to claim 1 , wherein the silicone adhesive is a crosslinked silicone adhesive.
7 . The adhesive sheet according to claim 1 , wherein the N,N-substituted amino group is —NR 1 R 2 , where in and R 1 and R 2 may be the same group, or may be respectively different groups.
8 . The adhesive sheet of claim 7 , wherein R 1 and R 2 are each independently an alkyl group, an aryl group, or an aralkyl group
9 . The adhesive sheet of claim 1 , wherein the heterocyclic group is derived from a heterocycle in which at least one of the atoms configuring the ring is a heteroatom, that are the same or different in the same ring.
10 . The adhesive sheet of claim 1 , wherein heterocycle comprises multiple rings of a bicyclic type heterocycle or a tricyclic type heterocycle.
