A PRODUCT COMPRISING A PROTECTED MICROSTRUCTURED AREA, AND A METHOD AND A DEVICE FOR PRODUCING THE SAME

摘要

According to the invention, a bare diffractive microstructured area (42) on a product is protected against wearing by means of one or more protruding elements (49). In an embodiment of the invention, the product (5) is provided with a depression (43), whose bottom is further provided with a diffractive microstructured area (42). Thus, the rim areas of the depression (43) form a protruding element (49) with respect to said microstructured area (42). If the product (5) is rubbed, for example, against the surface (77) of a table, said protruding element (49) prevents the rubbing surface (77) from having a physical contact with the microstructured area (42). According to the invention, the microstructured area (42) does not need to be protected with a transparent protective layer (54), which entails significant cost savings.
