Abstract
Adhesive articles and release liners are described. The release liners include nonadhesive components such as nonadhesive particulates along their release face. Upon incorporation in an adhesive article and exposure of an adhesive face thereof, at least a portion of the nonadhesive components are carried along the adhesive face. The release liners also include a deformable layer. The inclusion of the deformable layer in the release liner and the inclusion of the nonadhesive components in the adhesive region imparts repositionable or slidability characteristics to the article.
Claims50
An adhesive article comprising:
- an adhesive assembly including a substrate defining a first face and a second face oppositely directed from the first face, and adhesive disposed on at least one of the first face and the second face thereby defining an adhesive face;
- a release liner assembly including a release liner substrate defining a first face and an oppositely directed second face, a deformable layer disposed on one of the first face and the second face of the release liner substrate, and a release coating disposed on the deformable layer thereby defining a release face;
- and
- an effective amount of nonadhesive components disposed along the release face.
A method of imparting repositionable characteristics to an adhesive assembly including a substrate and a layer of adhesive disposed on the substrate, the adhesive layer defining an adhesive face, the method comprising:
- providing a release liner assembly including a release liner substrate defining a first face and an oppositely directed second face, a deformable layer disposed along at least one of the first and second faces of the release liner, and a release coating disposed along the deformable layer thereby defining a release face;
- disposing an effective amount of nonadhesive component(s) on the release face;
- contacting the release face of the release liner with the adhesive face of the adhesively assembly;
- and
- whereby upon separating the release liner from the adhesive assembly to thereby expose the adhesive face, at least a portion of the nonadhesive component(s) is disposed along the adhesive face.
A method of producing a repositionable adhesive article, the adhesive article including (i) an adhesive substrate, (ii) an adhesive layer disposed along the adhesive substrate and defining an adhesive face, and (iii) a release liner having a release substrate, a deformable layer disposed along the release substrate, and a release coating on the deformable layer defining a release face, the method comprising:
- providing an effective amount of nonadhesive components along at least one of the adhesive face and the release face;
- and
- contacting the adhesive face with the release face to thereby produce a repositionable adhesive article.
