Abstract
An adhesive article comprising a first substrate having thereon an adhesive layer, wherein the adhesive layer comprises a cured adhesive composition of a multifunctional ethylenically unsaturated siloxane polymer; and the first substrate comprises a polymer film, paper, a metal film, glass, ceramic, or a combination thereof; and wherein the adhesive layer has a microstructured surface that is substantiously continuous, and wherein the microstructured surface forms an array or pattern. The adhesive article is used to make laminated articles that spontaneously wet, and when applied to a substrate, remain removable or repositionable, even after long periods of time. The adhesive composition may be used in transfer adhesive films, and in laminated articles suitable for use in optical applications.
