Abstract
Abstract A decorated object having a spacial surface structure which is formed of unevennesses of the surface. An optical interference layer system consisting of at least three layers of alternating refractive indices is applied directly onto the spacial surface structure. The unevennesses typically extend laterally more than 1 millimeter, wherein ambient light reflected from the optical interference layer system upon the spacial surface structure produces a play of colors.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
52 words
A decorated object having a surface structure which is formed by unevennesses of the surface, wherein a) an optical interference layer system which consists of at least three layers of alternating refractive index is applied directly on the surface structure, and b) the unevennesses typically extend laterally to more than 1 millimeter.
Claim 2
Dependent Claim
52 words
A decorated object having a surface structure which is formed by unevennesses of the surface, wherein a) an optical interference layer system which consists of at least three layers of alternating refractive index is applied directly on the surface structure, and b) the unevennesses typically extend laterally to more than 1 millimeter.
Claim 3
Dependent Claim
27 words
The object as claimed in claim 1, wherein the layer thicknesses of the individual layers have a constant magnitude in the direction of the respective surface normal.
Claim 4
Dependent Claim
27 words
The object as claimed in claim 1, wherein the layer thicknesses of the individual layers have a constant magnitude in the direction of the averaged surface normal.
Claim 5
Dependent Claim
27 words
The object as claimed in claim 1, wherein the layer thicknesses of the individual layers are determined by a function of the respective height of the unevenness.
Claim 6
Dependent Claim
26 words
The object as claimed in claim 1, wherein the layer system or individual layers of the system consist of a layer with an inhomogeneous refractive index.
