    Abstract: An adhesive sheet includes an adhesive layer including a surface provided with a fine structure. The fine structure includes a plurality of convex structures. Each of the convex structures includes two or more parts joined to each other via an interface. The two or more parts include a first part present at a top of the convex structure and made from an adhesive material, and a second part present in a lower side of the first part. The second part is harder than the first part. The adhesive sheet provides a gap between adjacent ones of convex structures of the adhesive sheet after the convex structures are applied to a subject.

    Abstract: A micro-structured optically clear adhesive, including a first major surface and a second major surface, wherein at least one of the first and second major surfaces comprises a micro- structured surface of interconnected micro-structures in at least one of the planar dimensions (x-y), is disclosed. The micro-structured optically clear adhesive has a tan delta value of at least about 0.3 at a lamination temperature and is non-crosslinked or lightly crosslinked. The micro- structured surface may include indentations having a depth of between about 5 and about 80 microns. A method of laminating a first substrate and a second substrate without the use of a vacuum is provided. The method includes providing a micro-structured optically clear adhesive, removing a release liner from a first side of the micro-structured optically clear adhesive, contacting the first side of the micro-structured optically clear adhesive with a surface of the first substrate, removing a micro-structured release liner from a second side of the micro-structured optically clear adhesive to expose a micro-structured surface, and contacting the micro- structured surface with a surface of the second substrate.
