Abstract
The invention provides pressure-sensitive adhesive (PSA) coated articles, including tapes and transfer coatings, having microstructured surfaces and methods of making pressure-sensitive adhesive articles bearing such microstructured surfaces. The performance properties of the pressure-sensitive adhesive articles can be tailored by independently varying the microstructure and the rheological properties of the pressure-sensitive adhesive.
Claims20
A coated substrate comprising a substrate coated on at least one side with a continuous layer of a pressure-sensitive adhesive having a microstructured surface, wherein the microstructured surface comprises a series of features and wherein the lateral aspect ratio of the features range from about 0.1 to about 10.
