ABSTRACT:
A marking (4, 5) is formed in an outer layer (3; 23; 43) comprising a polymer material with an inorganic main chain and with certain visual properties by at least one region (9; 29; 49) of the outer layer (3; 23; 43) of which at least one of the visual properties shows a deviation, visible to the human eye, from the same property in other regions (9; 29; 49?) of the outer layer (3; 23; 43). Since the marking (4, 5) is obtained by means of at least a locally changed visual property of material of the outer layer (3; 23; 43) itself, the marking (4, 5) does not constitute a substantial interruption of the outer layer (3; 23; 43), and the application of the marking (4, 5) does not cause any substantial unevennesses in the outer layer (3; 23; 43). The following are further described: an element having such an outer layer (3; 23; 43) and a method of applying such a marking (4, 5).
