Definitions

• the present invention relates to a security element for bank notes, security papers and documents in general.
• These security elements generally have metallic, magnetic, microprinted, fluorescent threads, which mostly use a layer of aluminum deposited in vacuum, on which lettering is provided, for example by selective demetallization, and magnetic areas are provided being deposited in any manner.
• color elements also variously distributed, which range from holography to color-changing pigments to dichroic techniques and so forth, in which the color variation depends on the variation of the incidence of the light that strikes them.
• the aim of the present invention is to solve the problems cited above, by providing a security element for bank notes, security papers and documents in general that allows to combine security characteristics that can be detected immediately by the user with additional security characteristics that can be detected by an apparatus, without thereby having to resort to band metallization operations and the like.
• an object of the invention is to provide a security element that can be produced by means of processes that can be performed in a single pass with very low costs.
• Another object of the present invention is to provide a security element that allows to combine multiple security characteristics, consequently increasing the anti-forgery potential.
• Another object of the present invention is to provide a security element for bank notes, security papers and documents in general that is simplified in its execution while providing the greatest assurances of reliability.
• a security element for bank notes, security papers and documents in general characterized in that it comprises at least two adjacent regions without metallic materials, one of said regions having a layer of material whose light refraction varies with the angle of incidence of the light, the other region having a layer of material having constant reflection, at least one of said regions forming areas without material in order to form graphic markings, characters and the like that can be detected visually.
• Figure 1 is a plan view of the security element, shown schematically as a thread
• Figure 2 is a sectional view, taken along the line II-II of Figure 1;
• Figure 3 is a sectional view, taken along the line III-III of Figure 1; and Figure 4 is a sectional view, taken along the line IV-IV of Figure 1.
• the security element 1 for bank notes, security papers and documents in general shown schematically in the accompanying drawings as a thread but equally providable as a stripe or patch, by using conventional techniques, generally comprises a backing layer 2, which is constituted for example by polyester and advantageously has, in a specific embodiment that must not be considered as limitative, a width of approximately 4 mm.
• thermoadhesive layer generally designated by the reference numeral 3, is provided on the lower face of the backing layer 2.
• the particular feature of the invention consists in that on at least one of the faces of the backing layer 2 there are two regions without metallic materials, which are arranged adjacent.
• the two regions are arranged longitudinally side by side, but they can be arranged adjacent in various manners, such as with a transverse alternation, a sequential alternation, or the like.
• one of the regions for example the one designated by the reference numeral 10, is provided by means of a layer of material whose light refraction varies according to the variation of the angle of incidence of the light.
• said region is obtained by means of a holographic lacquer, over which an embossing is performed in order to impress the holographic image; to complete the assembly, a colored ink 15 is printed over the embossing.
• holographic printing it is possible to perform, by way of conventional methods, dichroic printing or the application of material that changes color according to the incidence of the light.
• metal-free regions allows to perform all the processes in a single pass.
• the other region i.e., the region 11, is formed by applying a material that has constant reflection, such as for example an ink that can be of the same color as the ink used for printing over the embossing in the case of holographic printing, or of a different color.
• Areas without material, i.e., negative areas, designated by the reference numeral 20 are provided on one of the regions, in the specific example on the region 11 , and allow to form graphic markings, characters and the like that can be detected visually.
• the areas without material may also optionally be provided in the color-changing region 10.
• thermoadhesive layer 42 is provided externally.
• the security element is constituted by stripes or patches
• the sequence of the layers is modified according to the different type of execution, without altering the concept of execution as regards the adjacent arrangement of the regions 10 and 11.
• the regions bearing the layer of material whose light refraction varies according to the angle of incidence can be obtained by means of fluorescent inks, phosphorescent inks, inks with diversifiable infrared absorbance, and these substances advantageously are not arranged at the areas without material.
