Abstract
An article 10 is provided with an adhesive layer 14 that includes an adhesive, a release layer 12 that is stacked on the adhesive layer 14, and an air layer 16 that is interposed between the adhesive layer 14 and the release layer 12. On a surface 12a of the release layer 12 that opposes the adhesive layer 14, microprotrusions 20 that contact the adhesive layer 14 with tips 20a are provided. The microprotrusions 20 are provided with a wall-shaped portion 22 having a shape that at least partially surrounds the air layer 16 between the adhesive layer 14 and the release layer 12. The wall-shaped portion 22 protects a main portion 14a of the adhesive layer 14 that is adjacent to the air layer 16 from contamination. By selecting a shape, dimensions, and the like of the micro protrusions 20, a release force of the release layer 12 can be adjusted to a desired range.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
