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.

Adhesive composition and articles made therefrom

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.

Microstructured adhesive article and articles made therefrom

An adhesive composition comprising a multifunctional ethylenically unsaturated siloxane polymer, a monofunctional ethylenically unsaturated siloxane macromer, and a 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.

An antireflection film and method of making same includes a substrate having a first surface and a second surface, an inorganic layer deposited on the first surface of the substrate, and an optically active polymer layer formed by curing a curable composition in situ on the inorganic layer, the polymer layer having a refractive index not greater than about 1.53 over the wavelength range of 400 nm to 700 nm and a thickness of from about 20 nm to about 200 nm, and an adhesive layer deposited on the second surface of the substrate.
