Abstract
Official abstract text for this publication.
A pressure sensitive adhesive sheet may include a base material and a hot-melt pressure sensitive adhesive layer which contains a softener, and further include a barrier layer disposed between the base material and the hot-melt pressure sensitive adhesive layer, the barrier layer containing at least one selected from the group consisting of a polyester-based resin, a polyurethane-based resin, and a polyolefin-based resin. The polyester-based resin may be at least one of a polyester resin or a modified polyester resin.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A pressure sensitive adhesive sheet comprising a base material and a hot-melt pressure sensitive adhesive layer containing a softener, the pressure sensitive adhesive sheet further comprising a barrier layer disposed between the base material and the hot-melt pressure sensitive adhesive layer, the barrier layer comprising at least one selected from the group consisting of a polyester-based resin and a polyurethane-based resin, wherein the polyester-based resin is at least one of a polyester resin or a modified polyester resin, wherein a total content of the polyester-based resin and/or the polyurethane-based resin in the barrier layer is at least 80 mass %, wherein the hot-melt pressure sensitive adhesive layer is a layer comprising a rubber and a tackifier. 2 . The pressure sensitive adhesive sheet according to claim 1 , wherein the polyester-based resin and the polyurethane resin each have a glass transition temperature of from 40 to 130° C., and the polyolefin resin has a softening point of from 0 to 100° C. 3 . The pressure sensitive adhesive sheet according to claim 1 , wherein the polyester-based resin has a glass transition temperature of from 20 to 100° C. 4 . The pressure sensitive adhesive sheet of claim 1 , wherein the base material comprises at least one of paper or an olefin-based resin. 5 . The pressure sensitive adhesive sheet according to claim 4 , wherein the base material comprises the paper having a density of greater than 0.9 g/cm 3 . 6 . The pressure sensitive adhesive sheet according to claim 5 , wherein the density of the paper is from 0.9 to 1.5 g/cm 3 . 7 . Pressure sensitive adhesive sheet of claim 1 , wherein the barrier layer has a thickness of from 0.01 to 10 μm. 8 . The pressure sensitive adhesive sheet of claim 1 , wherein the polyester-based resin has a glass transition temperature of from 30 to 90° C. 9 . The pressure sensitive adhesive sheet of claim 1 , further comprising a release liner on the hot-melt pressure sensitive adhesive layer on an opposite side of the barrier layer.
