Abstract
Abstract An embossing foil includes a signing layer which can be written upon, in conjunction with a layer having a structure giving an optical diffraction effect such as a hologram. The signing layer may be clear in the region over the diffraction structure or alternatively the signing layer, over the diffraction structure, may be of a patterned or grid configuration defining openings through which the structure therebeneath can be viewed. The foil may also include a magnetic layer for the storage of variable data which can be readily accessed.
