The invention concerns an optically variable element, in particular an optically
variable safeguard element for safeguarding banknotes, credit cards and the like,
and a security product and a foil, in particular an embossing foil or a laminating
foil, with such an optically variable element. The optically variable element has
a thin film layer (54, 55, 58) for producing color change by means of interference
and a further layer (51, 52, 53, 59). The thin film is in the form of a
partial thin film element which covers the surface region of the further layer
only in region-wise and pattern-shaped manner.
