Benefits of technology

[0012] It is an advantage to provide an adhesive-backed article that has pathways in the adhesive for fluid egress and permits positioning of the article without adversely affecting the appearance of the article. The channels define pathways to the periphery of the article that permit the flow of fluid trapped between the adhesi

Problems solved by technology

The placement of a film into a specific position prior to the formation of a bond between the adhesive and the substrate is often difficult, but important for aesthetic reasons.
Such articles can often be particularly difficult to reapply if they inadvertently adhere to the substrate.
The inability to slide the adhesive-backed article in place can adversely affect the positioning of the article or cause dam

Surface Roughness Test

[0075] The surface topography of a film is measured using the RST Plus surface profiling system available from Wyko Corporation in the vertical scanning interferometer mode (VSI) at a magnification of 1.2× and a pixel size of 13.64 μm.

[0076] The system uses an interference microscope and a computer algorithm to analyze the surface. In the system, a white light beam passes through a microscope objective to the sample surface. A beam splitter reflects half of the incident beam to a reference surface. The beams from the sample and the reference surface recombine at the beam splitter to form interference fringes which are alternating light and dark bands that are visible when the surface is in focus. The reference arm containing the interferometric objective moves vertically to scan the surface at varying heights using a linearized piezoelectric transducer to control the motion. The interference fringes for white light are present only over a very shallow depth ...

examples 1-11

Examples 1 -11, produced in accordance with the present invention, exhibit good appearance, good air bleedability, and at least fair slidability. The appearance was determined by visual examination with the unaided eye. A good appearance result indicates no observable underlying structure. A poor appearance results if the pattern is visible. With respect to Examples C1-C3, the average volume per any 500 μm diameter circular area is indeterminate since some 500 μm diameter circular areas do not have channels. Additionally, Examples C1-C3 have poor appearance indicating that patterns created by the channels are visible with the human eye after application.

[0097] Samples from each Example measuring approximately 2.54 cm by 2.54 cm were then laminated to a clean glass plate using a plastic squeegee. The samples were then analyzed for surface roughness and periodicity according to the procedure described above. Example C4 is the vinyl film with no adhesive laminated to it, and C5 is the ...

Abstract

Methods of preparing adhesive-backed articles and methods of applying adhesives backed articles are described. The adhesive-backed articles include a compliant film and a pressure-sensitive adhesive having a microstructured surface opposite the compliant film.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation of U.S. patent application Ser. No. 10 / 357,151 filed Feb. 3, 2003, now pending, which is a continuation-in-part of U.S. patent application Ser. No. 09 / 311,101, filed May 13, 1999, now issued as U.S. Pat. No. 6,524,675 on Feb. 25, 2003.FIELD OF THE INVENTION [0002] The present invention relates to an adhesive-backed article, more particularly to such an adhesive-backed article having an adhesive with a microstructured surface bonded to a compliant film, and even more particularly to channels, with a specific volume per unit area, formed by the microstructured surface in the adhesive which permit the desirable properties of positionability and fluid egress to a periphery of the article without adversely affecting the surface appearance of the film after application onto a substrate. BACKGROUND OF THE INVENTION [0003] Films are often bonded to substrates utilizing pressure-sensitive adhesives. The films a...
