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.
