Abstract
Official abstract text for this publication.
An adhesive tie layer includes a binder including a multifunctional acrylate and a polyurethane, surface treated nanoparticles dispersed in the binder, and a plurality of interconnected voids. A volume fraction of interconnected voids in the adhesive tie layer is not less than about 10%.
First claim
Opening claim text (preview).
What is claimed is: 1. An adhesive article, comprising: an adhesive forming an adhesive layer; a polymeric substrate; and an adhesive tie layer between the adhesive layer and the polymeric substrate, the adhesive tie layer securing the adhesive layer to the polymeric substrate, the adhesive tie layer comprising: a binder comprising a multifunctional acrylate and a polyurethane; surface treated nanoparticles dispersed in the binder; and a plurality of interconnected voids, a volume fraction of interconnected voids in the adhesive tie layer is not less than about 10%, wherein the adhesive fills at least a portion of the plurality of interconnected voids. 2. An adhesive article according to claim 1 , wherein the adhesive comprises an acrylic adhesive. 3. An adhesive article according to claim 1 , wherein the adhesive tie layer has a thickness in a range from 0.1 to 10 micrometers. 4. An adhesive article according to claim 1 , wherein the adhesive article has a refractive index of 1.4 or greater. 5. An adhesive article according to claim 1 , wherein the adhesive article has an optical haze value that is less than an optical haze value of the adhesive tie layer. 6. An adhesive article according to claim 1 , further comprising a primer layer separating the adhesive tie layer and the polymeric substrate.
