Flake for application in hidden protection

FIELD: money. SUBSTANCE: invention may be used for counterfeit protection of banknotes, packages, stamps and commercial items. Hidden flakes, having one or several symbols and/or selected shape, are used in composition, such as printing dye or ink. Composition may include the main pigment and hidden pigment flakes, which comply with visual characteristics of the main pigment. In other versions transparent or non-transparent hidden flakes are mixed into carrier with the main pigment. Transparent or non-transparent hidden flakes may also be mixed into varnish base to create transparent composition, which may be applied over existing protective criterion. Hidden flakes are not easy to detect in process of accidental examination in visible light. Illumination of hidden protective criterion by ultraviolet light causes fluorescence of hidden flake, which makes it possible for user to identify its position. Hidden flakes, having one or several symbols, may also be detected with application of invisible radiation, and then symbol may be read on hidden flake in visible light.

Provision of frames or borders around pigment flakes for covert security applications

Opaque flakes, such as pigment or bright flakes used in paints and inks, have a selected shape and/or other indicia to provide a covert security feature to an object. Shaped opaque covert flakes are not readily detectable by causal observation, but in some embodiments are easily seen at 50X magnification. In manufacturing the flakes a sheet of embossed frames are provided having embossed symbols or indicia within. Upon removing a coating from the embossed sheet the coating material tends to break along frame lines or grooves and the resulting flakes are substantially uniform in size. In order to have the flakes break along frame lines or grooves more readily than along the embossing or grooves defining indicia within a frame, the frames are provided with a deeper groove than indicia grooves. As well a groove having a different shaped profile conducive to breakage can be used for the frame grooves whereas a groove having a profile less conducive to breakage can be used to form the indicia grooves. We have found that the flakes can be further protected from breakage by coating them in a protective coating. This coating may have other features which makes the logo more visible.
