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

Embodiment Construction

[0022]The present invention may relate to adhesive articles such as those used, for example, in industrial, advertising, promotional, labeling, vehicular, traffic and safety, architectural and transportation related graphics. The adhesive articles may provide one or more of air egress or release, repositionability, and / or slidability for easy application to a substrate. The present invention may also relate to methods of making such adhesive articles. Further, the present invention may relate to a carrier web or intermediate assembly, such as a release liner, that may be suitable for adhesive articles.

[0023]The adhesive articles may generally comprise an adhesive layer, and surface contact elements or non-adhesive material forms randomly distributed along a surface of the adhesive layer. The non-adhesive material may be dispersed in a particular or discrete volume, density, quantity or amount which can create a discontinuity in the number of particles provided across the surface. Th...

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. The adhesive articles may find usefulness in a variety of applications including, for example, advertising and promotion, screening and tinting, transportation, traffic and safety, labeling, industrial and graphic displays such as those used on vehicles and architectural surfaces.BACKGROUND OF THE INVENTION[0003]Pressure sensitive adhesives have enjoyed great acceptance for their convenience of use. Pressure sensitive adhesives are used in a variety of applications including tapes, labels and articles containing graphic images. Pressure sensitive adhesives have a number of advantages such as strong bonding and simplicity of application. One drawback of these pr...
