AN ABSORBING ARTICLE WITH ZONES OF DIFFERENT SURFACE PROPERTIES

摘要

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 mum in diameter, with an average size of the grottos being less than 300 mum.
