    Abstract: Provided is a pressure sensitive adhesive sheet containing, on a substrate or a release material, a resin layer that includes a resin part (X) containing a resin as a main component, and a particle part (Y) consisting of fine particles, at least a surface (±) of the resin layer being opposite to the side thereof on which the substrate or the release material is provided having pressure sensitive adhesiveness, wherein plural concave portions having a maximum height difference of 0.5 µm or more exist in a predetermined region (P) on the surface (±), and 95% or more of the plural concave portions existing inside the region (P) have shapes differing from each other, and one or more such concave portions exist in a predetermined region (Q) on the surface (±). When attached to an adherend, the pressure sensitive adhesive sheet can readily remove air accumulation to be formed and therefore exhibits excellent air escape property, and has good blister resistance and pressure sensitive adhesion characteristics.

    Abstract translation: 本发明提供一种压敏粘合片，其在基材或剥离材料上包含树脂层，该树脂层包含含有树脂作为主要组分的树脂部分（X）和至少包含微粒的颗粒部分（Y） 所述树脂层的与设置有所述基板或所述剥离材料的一侧相反的表面（±）具有压敏粘合性，其中，具有0.5μm或更大的最大高度差的多个凹部存在于预定区域 （P）中存在的多个凹部中的95％以上具有彼此不同的形状，并且在该表面（±）上的预定区域（Q）中存在一个或多个这种凹部 表面（±）。 当粘附到被粘物上时，压敏粘合剂片能够容易地除去要形成的空气积聚，并因此表现出优异的空气逸出性，并且具有良好的起泡性和压敏粘合性。

    Abstract: Provided is a pressure sensitive adhesive sheet containing, on a substrate or a release material, a resin layer that includes a resin part (X) containing a resin as a main component, and a particle part (Y) consisting of fine particles, at least a surface (±) of the resin layer being opposite to the side thereof on which the substrate or the release material is provided having pressure sensitive adhesiveness, wherein plural concave portions having a maximum height difference of 0.5 µm or more exist in a prescribed region (P) on the surface (±), and 95% or more of the plural concave portions existing inside the region (P) have shapes differing from each other, and when the surface (±) of the resin layer is attached to a smooth surface of a light transmissive adherend having a smooth surface, the areal ratio of the attached area against the smooth surface of the light transmissive adherend to the surface (±) is 10 to 95%. When attached to an adherend, the pressure sensitive adhesive sheet can readily remove air accumulation to be formed and therefore exhibits excellent air escape property, and have good blister resistance and pressure sensitive adhesive characteristics.
