Title: SIMULATED OPAL ARTICLES
Abstract:
A simulated opal article, including a layer (1) of a reproduction of a surface of an opal applied to the surface of a two-dimensional hologram or diffraction grating (2) formed from two randomed patterned orthogonally embossed holograms or diffraction gratings. The two-dimensional hologram or diffraction grating (2) is formed by embossing a first pattern onto a suitable embossable surface with a second pattern double embossed or superimposed over the first pattern in such a manner that both patterns are visible at similar intensity and become interactive, thereby creating an interactive spectrogram with a three-dimensional effect resembling an opal and being sufficiently flexible so that it may be adhered to a flat, convex, concave, uneven or undulating surface.
