Abstract
An adhesive composition comprising from about 2 to about 10 wt. % multifunctional ethylenically unsaturated siloxane polymer, from about 2 to about 10 wt. % monofunctional ethylenically unsaturated siloxane macromer, and from about 85 to about 96 wt. % vinyl monomer is described. The adhesive composition is used to make adhesive articles that, 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.
