Document Type and Number:
WIPO Patent Application WO/2013/042485
Kind Code:
A1
Abstract:
Provided is a sheet for protecting a coating film, which has a good initial adhesion force, wherein the long-term stability of the adhesion force is highly superior. The sheet for protecting a coating film provided by the present invention has, provided therein, an adhesive agent layer containing an isobutylene polymer as the main component. In the sheet for protecting a coating film, the element ratio of an oxygen atom as measured by an ESCA method on the surface of the adhesive agent layer is 1.0 to 8.0 at% of that on the entire surface of the sheet.
