Abstract
An absorbing element having an adhesive surface showing adhesive properties for adhering to a substrate wherein at least a part of the surface has been treated, resulting in alteration of the surface properties of the heat treated part of the surface. By heat treatment, it is possible to provide an adhesive surface having parts showing different colors, water absorption properties, and/or adhesive properties. These parts include grottos in a first facade of the absorbing element that are at least 5 μm in diameter, with an average size of the grottos being less than 300 μm.
Claims15
