The decorative element (2) has a microstructure (4) which generates an optical effect in incident light and/or with light passing through. In a first area (32), the microstructure (4) has a base surface (40) and several base elements (41) which have in each case an element surface raised or lowered compared with the base surface (40) and a flank arranged between the element surface and the base surface (40). The base surface (40) of the microstructure defines a base plane spanned by coordinate axes x and y. The element surfaces of the base elements (41) in each case run substantially parallel to the base plane. In at least one or more first zones of the first area (32), the element surfaces of the base elements (41) and the base surface (40) are spaced apart in a direction running perpendicular to the base plane (40) in the direction of a coordinate axis z by a first distance which is chosen such that a color is generated in the one or more first zones in particular by interference of the light reflected at the base surface and the element surfaces in incident light and/or in particular by interference of the light transmitted through the element surfaces and the base surfaces with light passing through.

MULTI-LAYER BODY AND METHOD FOR THE PRODUCTION THEREOF
The invention relates to a method for producing a multi-layer body, in particular a security element, wherein a partial first layer or a partial first layer system is created on a substrate, said partial first layer or partial first layer system being provided in a first portion and not in a second portion. Subsequently, a partial second layer or a partial second layer system is created, said partial second layer or partial second layer system being provided in a third portion and not in a fourth portion, which third portion overlaps with the first and second portions. The partial first layer or the partial first layer system is then formed as a mask structure using the partial second layer or the partial second layer system.

The invention relates to an optically variable element having first and second diffraction gratings, which are high-frequency diffraction gratings and thus are reflective into the zeroth order of diffraction. Either a first color is generated by the first diffraction grating and simultaneously a second color different from the first color is generated by the second diffraction grating at a certain angle of rotation and a certain illumination angle, or a visible color is generated substantially only by the first diffraction grating at a first angle of rotation and a visible color is generated substantially only by the second diffraction grating at a second angle of rotation.
