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.
