Adhesive articles having repositionability or slidability characteristics

Abstract

An adhesive article exhibiting air release or egress, repositionability, and / or slidability characteristics. An adhesive article comprises an adhesive layer comprising an adhesive surface comprising discrete forms of non-adhesive material randomly distributed on the patterned surface and at least partially embedded in the adhesive layer. The discrete forms of non-adhesive material provide areas of no or minimal adhesion and provide the article with some level of repositionability or slidability. The adhesive surface comprising the non-adhesive forms may be patterned to provide an adhesive surface with a contact surface and recessed area or channels that provide the article with a route for air to flow out from under the construction. An article may be formed by providing a release liner, applying discrete forms of non-adhesive material to a surface of the release liner, at least partially embedding the non-adhesive forms, and embossing the release liner.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application is a division of U.S. patent application Ser. No. 11 / 757,535 filed Jun. 4, 2007, which is incorporated herein by reference in its entirety.TECHNICAL FIELD OF THE INVENTION[0002]The present invention relates to adhesive articles and methods of making the same.

Benefits of technology

[0006]The present invention relates to an adhesive article that exhibits air release or egress, repositionability, and/or slidability characteristics. Air egress may be provided by an adhesive surface having a patterned topography comprising recessed areas such as, for example, grooves and channels. Repositionability and/or slidability may be provided by having discrete quantities of surface contact elements or no

Problems solved by technology

One drawback of these products is the initial tack of the pressure sensitive adhesive.

When the product is a graphic image and is applied over an area like a wall or truck panel, there is the possibility of trapping air under the product and forming deformations of the surface such as with bubbles or wrinkles.
