Definitions

• the present invention relates to a security strip intended to be incorporated in part in the structure of a security document at least partially made of fibers.
• This integration can be made in "embedded” form, in which case the wire is integrated completely into the mass of the paper.
• the windows are visible by reflection, while the submerged parts are only visible by transmission.
• reflection is meant the phenomenon by which the rays of incident light are reflected on the surface of the support.
• this integration technique makes that the security thread is visible only from the upper face of the paper, and still partially, that is to say at the windows.
• the present invention aim to fill this gap. It is also intended to facilitate the authentication of the security document that incorporates this banner, especially by the man in the street.
• the present invention in a first aspect, relates to a security strip intended to be incorporated in part in the structure of a security document at least partially made of fibers, this strip emerging on the surface of said document in the form of a set of windows, and comprising a transparent or translucent support material, covered, on one or the other of its opposite faces, with at least three distinct and superposed layers of coating.
• this strip comprises, among these three layers respectively designated first layer, second intermediate layer and third layer, a second intermediate layer which has an optical rendering different from that of the first and third layers.
• the second intermediate layer is opaque and comprises at least two regions at least partially free of coating, these two regions having respectively different contours and the first and third coating layers consist of at least one pattern, a part of the pattern of the first layer being visible through one of said two regions at least partially free of coating, while at least part of the pattern of the third layer is visible through the other of said two regions at least partially free of coating, said patterns being different from each other.
• an opaque intermediate layer allows on either side of it to affix complementary layers which will respectively be visible from the front face, and the reverse face of the strip.
• the intermediate layer has partially recessed regions of different contours these will be additional visible safety signs and the authentication of the banner by the man of the street will be facilitated. And together, the task of a fraudster will be made more complex.
• part of the pattern of the first layer is visible through one of these regions and that part of the pattern of the third layer is also visible through the other region makes the manufacture of the strip particularly complex, hence a greater difficulty for fraudsters to achieve the banner of the invention.
• said different optical renderings are selected from different colors, glosses, opacity / transparency and / or contrasts;
• said regions are totally devoid of coating; said regions are partially free of coating, and have the form of a screened network;
• said fourth layer is opaque and superimposes a portion of the pattern of the third layer
• the layer furthest from the support is covered with a transparent protective layer, such as a film or varnish.
• Another aspect of the invention relates to a security document such as a bank note. This is remarkable in that it comprises a strip according to one or the other of the preceding characteristics, which is incorporated within this document while emerging on the surface of at least one of its visible faces, in the form of a set of windows.
• the security document is coated locally with a deopacifying agent, that is to say improving the visibility of the strip where it does not emerge on the surface of at least one of the visible faces of the document.

• This security document is preferably based on cotton paper, with or without chemical pulp, cellulose-based paper or any other material containing fibers of different types and weights, including at least a portion of synthetic fibers. It is also possible to use a hybrid support combining polymer (s) and paper.
• a strip 2 is partially incorporated in the document 1, while emerging at its upper surface corresponding to the front face 10 of the note, in the form of a set of windows.
• the band extends according to the small transverse dimension of the bill.
• the zones of the strip 2 which are integrated in the mass of the note have been identified by the letter P and are therefore not completely visible, unlike the window areas F, as shown in FIG.
• the strip according to the invention comprises a transparent, or at least translucent, support material 4, such as a film of plastics material.
• this support material On the underside of this support material, that is to say in the direction of the back side 11, is a thickness 3 of adhesive or a mixture of adhesives intended to secure the entire strip 2 of security with the fibrous material of the document in which it will be inserted.
• the same material as that of the support 4 can be used.
• This coating is intended to protect all the information contained in layers 5, while allowing their readability.
• the assembly is covered, on the side of the front face by another layer 7 of adhesive, preferably of the same nature as the layer 3 (but not necessarily).
• FIG. 4B represents what is visible on the front side, that is to say in a direction of observation which is situated on the top of the layer 53.
• Figure 4C it symbolizes what is visible according to the reverse side of the stack
• the layer 51 is formed of a set of opaque patterns, for example consisting of a black ink printing cover.
• the second layer 52 which can be described as intermediate, has a different optical rendering than that of the first layer.
• different optical rendering it is meant that, when these two layers are observed with the naked eye, they can immediately be distinguished from one another, in particular by their color, their brilliance, their opacity. / transparency and / or their contrast different (es).
• a feature of the intermediate layer 52 is that it is opaque.
• any material having a real opacity can be used, and it will be preferred, for example, to form this layer by means of a metal deposit such as an ink impression containing gold, silver, copper, etc. metal particles.
• a thin layer of a metal for example aluminum or opaque copper, may be deposition under vacuum and then locally removed by washing with sodium hydroxide or with water to create zones. without coating.
• This layer 52 partially covers the first layer 51.
• regions 520 in negative which means that they are free of coating, these regions respectively having different contours.
• a first region 520 which consists of a window forming the number "5", and another region 520 which is constituted by the number "201”, inscribed upside down.
• this intermediate layer 52 rests a third layer 53 which also has a pattern 530 consisting here of the stylized representation of the letter "O" on the one hand, and in the presence of four squares on the other hand.
• the materials used for the patterns of the layer 51 are the same as those of the layer 53.
• the intermediate layer 52 makes it possible to differentiate between each other the layers 51 and 53, as well as the patterns that are present therein.

• This layer 54 is identical in nature or different from that of the second layer 52.
• This fourth layer 54 also exhibits perforated zones since the only region in which an occulting material is present is here limited to a circle 540.
• a fifth layer 55 covers the assembly. It is preferably of a different nature than the first and third layers. Particularly advantageously, this layer 55 consists of an effect ink chosen from the optically variable, iridescent, liquid crystal type so as to create color change effects according to the angle of observation.
