Definitions
- the present invention relates to the field of secure articles.
- security elements applied on the surface or introduced in bulk or in windows (s) in a secure article, for example a label, packaging, especially for drugs, food, cosmetics, electronic parts or spare parts.
- the secure article may in particular be chosen from among a means of payment, such as a bank note, a bank card, a check or a restaurant ticket, an identity document such as an identity card, a visa, a passport or driver's license, a secured card, a lottery ticket, a ticket or a ticket to events.
- a means of payment such as a bank note, a bank card, a check or a restaurant ticket
- an identity document such as an identity card, a visa, a passport or driver's license, a secured card, a lottery ticket, a ticket or a ticket to events.
- Patent applications EP 2 367 695, EP 2 585 308 and EP 2 586 014 and patent EP 2 454 102 disclose the effects of masking imbricated images by a revelation screen which, when the revelation screen and the image are superimposed, the observation of an image by displacement of the revelation frame with respect to the image or by change of the angle of observation.
- EP 2 740 607 a system comprising a revelation screen, a layer having pigments orientable by an external magnetic field and a magnetic layer having a north and south poles frame, the revelation frame and the weft of north and south poles being of different colors.
- WO 2014 096 794 discloses a first frame on which a second surface frame is embossed, the weft lines of the first frame having the same color in visible light and different colors when they are observed under a combination of visible and invisible lights and the two frames being such that the device has a different color, depending on the viewing angle, when exposed to a combination of visible and invisible lights.
- the invention aims to meet this need and has for its object, according to a first aspect, a secure article comprising a first optical structure and a second optical structure, or an assembly comprising a secure article and another object, the article secure one having a first optical structure and a second optical structure and the object comprising or forming the other of the first optical structure and the second optical structure,
- the first optical structure comprising a plurality of blocks of first optical structure disposed in different areas of the first optical structure, the first optical structure being one of a revelation frame and a combined image and the second optical structure being the other of the revelation frame and the combined image,
- each of the combined image blocks being composed of a plurality of nested images
- At least two blocks of first optical structure each enabling, when the revelation frame and the combined image are superimposed, for at least one given position and orientation of the revelation frame with respect to the combined image and for at least one angle of observation, the observation of an image revealed at each block of first optical structure, the images revealed at the two blocks of first optical structure showing different proportions of the nested images.
- the other aforementioned object is for example similar in its function and / or in its form to the secure article according to the invention.
- the secure article and the other object are bank notes, especially with the same fiduciary value.
- the secure article and the other object can then be differentiated from each other only by a serial number for example.
- each block reveals a certain proportion of each of the nested images of the combined image to form the revealed image .
- the proportion of a nested image is between 0 and 1, the value 0 being assigned to a nested image when the latter is not a component of the revealed image, that is to say when the latter is completely obscured by the revelation frame at the corresponding block and the value 1 being assigned when the entire nested image is a component of the revealed image, that is to say when the latter is not obscured at all by the revelation frame at the corresponding block.
- the subject of the invention is a secure article comprising a revelation frame and a combined image, or an assembly comprising a secure article and another object, the secure article comprising one of the revelation frame and the combined image and the object comprising or forming the other of the revelation frame and the combined image,
- the combined image being composed of a plurality of nested images, the revelation field having a plurality of blocks arranged in different areas of the revelation frame,
- the subject of the invention is a secure article comprising a revelation frame and a combined image, or an assembly comprising a secure article and another object, the secure article comprising the one of the revelation frame and the combined image and the object comprising or forming the other of the revelation frame and the combined image,
- the combined image having a plurality of blocks arranged in different areas of the combined image
- each combined image block being composed of a plurality of nested images
- At least two nested image blocks each for, when the revelation frame and the combined image are superimposed, for at least one given position and orientation of the revelation frame with respect to the given combined image and for at least one an angle of observation, the observation of an image revealed at each block, the images revealed at the two blocks showing different proportions of the nested images.
- the combined image or each of the combined image blocks comprises a periodic alternation of nested image elements in one or more directions.
- the combined image or each of the combined image blocks may comprise at least two nested images, preferably at least three.
- the combined image or each of the combined image blocks may comprise at least two elements of each nested image, preferably at least three.
- the successive elements of the same nested image may be spaced apart by a distance defining a period.
- the or each period may be between 10 ⁇ and 1 mm, preferably between 50 ⁇ and 200 ⁇ .
- the nested picture elements belonging to different nested pictures are of different colors.
- color is defined by the combination of three parameters of hue, saturation and brightness. The hue is the perception of the color measured on a color wheel, the saturation is the purity of the color, and the brightness is the degree of lightening or darkening of a color.
- the nested picture elements belonging to different nested pictures are of different hues.
- the elements belonging to different nested images may be different in their aspects, in particular their hues, opacities, saturations, luminescences or glosses, and / or may have a contrast, notably a saturation contrast. , intensity, hue and / or luminance, and / or a color difference sufficient to distinguish, especially under white light, two adjacent imbedded image elements when observed with a certain magnification.

- Article 10 comprises a polarizing filter on which the second image 120 has been formed as a revelation screen 4.
- the article 10 comprising the second image 120 in the form of a revelation screen 4 is superimposed on the first image 110 in the form of a combined image I produced by the imager 100, which emits polarized light.
- the article 10 comprising the revelation screen 4 can be displaced by a translation movement along the axis X relative to the combined image I displayed by the screen of the electronic imager 100, so as to change the the revealed images I r .
- Such a method makes it possible to authenticate and / or identify the security article 1 according to several security levels.
- the positioning of the revelation screen 4 comprising the polarizing filter according to the orientation making it possible to observe the opacity of the polarizing filter, this observation being visible only on a screen emitting polarized light, for example an LCD-type screen, provides a first level of security.
- the electronic imager 100 is a screen, in particular of the LCD type, comprising a plurality of pixels preferably forming a combined image, for example as described in FIG. 36A.
- the invention is not limited to the illustrated examples.
- the secure article can be made with other first, second or third level security, for example.
