Benefits of technology

The patent describes a new label that is resistant to tampering and can be applied quickly. The label uses a special adhesive that hardens and becomes permanent, making it difficult to remove or change the data. The label also has a special surface structure that reflects light in a unique way, creating a shiny and attractive appearance. This new label technology is useful for a variety of applications, such as in automated equipment or as a scratch off label.

Problems solved by technology

The combination of a diffractive security device with a scratch off underlying layer provides a considerable barrier to a counterfeiter to duplicate the diffractive image after removal of the scratch off layer for examination, thus making counterfeit or unauthorised access and reuse of the data more difficult.

Embodiment Construction

[0050]FIG. 1 illustrates the carried scratch off label structure consisting of an optical variable effect generating structure Layer 1 such as a hologram or diffractive or interference structure, a layer of metallisation to provide reflectivity (2) such as aluminium although other metals may be used provide different effects, a weak scratch off adhesive layer (3) designed to allow layers 1&2 to be easily abraded away. The scratch off adhesive would typically be a latex based adhesive or ink and of high opacity to help conceal underlying data. Layer 4 is the carrier layer such as a frangible material such as frangible acetate or vinyl or a conventional carrier such as OPP or PET—typically 19-50 urn. Layer 5 is a pressure sensitive adhesive and in some preferred options a curable adhesive where the curing action is triggered by applying the adhesive coated layer to a substrate pre-printed with catalyst. Layer 6 are the data or indicia to be protected in this case located on the base s...

Abstract

Embodiments of the invention, therefore, provide improved systems and methods for tracking targets in a simulation environment. A security device having a first layer that carries indicia arranged to present covert information. Embodiments of the invention may include a second layer that carries decoding optical elements. In some embodiments, the second layer is arranged to be moveable relative to the first layer from a first position to a second position. In some embodiments, when in the second position, the optical elements serve to cooperate with the indicia so as to reveal the covert information for visual observation.

Description

BACKGROUND OF THE INVENTION[0001]Optically variable diffractive devices such as holograms and optical interference based devices are now used to prove the authenticity of items of value and to prevent their fraudulent duplication for example for banknotes, plastic cards, value documents such as fiscal stamps, travel documents such as passports and for the authentication of valuable goods as an anti-counterfeit measure. Scratch off inks are used to protect hidden numbers which can be revealed by scratching off the ink—for example on lottery tickets for number protection and for protecting secure validation numbers on validation cards, such as pre-pay telephone cards. Scratch off diffractive and holographic hot stamping foil is also used in this type of application with the advantage that the holographic foil is hard to replicate or obtain and therefore protects the number from alteration or prior use and re-sale.[0002]This invention relates to an optically variable diffractive device...
