The present invention relates to a release liner, an adhesive article comprising the same, a process for producing the release liner, and a process for decorating an object using the adhesive article. According to an embodiment, the release liner comprises a carrier substrate (10), a thermoplastic polymer layer (20) applied on one side of the carrier substrate (10), and a release layer (30) applied on the thermoplastic polymer layer (20) on the side opposite to the carrier substrate (10). The thermoplastic polymer layer (20) and the release layer (30) include a network of ridges (25), which result in elevations of the surface of the release liner on the side of the release layer. The surface on the side of the release layer (30) has a roughness at least between the ridges (25), such that it has a plurality of pits (1, 2, 3). The average number of pits (1, 2, 3) per an area of 3.4 mm2 of the plan view of the release liner surface is at least 50 as determined with a confocal 3D laser scanning microscope at a magnification of 100. The pits (1, 2, 3) extend at least to a level of 10.0 µm above the deepest point of the deepest pit (1) within said area of 3.4 mm2.
