A security sheet including at least one paper substrate, at least one watermark produced in the paper substrate, the watermark having an exterior outline, at least one aperture of regular edge, produced by ablation of the paper substrate, and at least one security film that is at least partially superposed on the watermark and on the aperture. In the sheet, the at least one aperture lies inside the watermark, such as bounded by its exterior outline.

Security paper

The aim of the present invention is to provide a fluid composition that can form a coating, said composition being characterized in that it contains, at least in a solvent medium, an effective amount of at least one natural virucide selected from among lauric acid, monolaurin, lactoferrin and essential oils having antiviral activity and/or one of the precursors thereof, said composition having a viscosity of 30 mPa&#xb7;s to 40 Pa&#xb7;s at room temperature and pressure.

Fluid compositions that can form a coating having antiviral properties

The present invention relates to an information medium to be handled by a large number of users, such as a banknote, and having antiviral properties, and to a method for making same.

Information medium having antiviral properties, and method for making same

The present invention relates to a crumple-resistant security sheet comprising fibers; an anionic polymer in a proportion lying in the range 5% to 45% by dry weight relative to the total dry weight of the fibers, and presenting a glass transition temperature greater than 40&#xb0; C.; and a main cationic flocculation agent in a quantity lying in the range 1% to 5% by dry weight relative to the total dry weight of the fibers.

Crumple-resistant security sheet, a method of manufacturing such a sheet, and a security document including such a sheet

The present invention relates to a security structure (), comprising at least one first fluorescent composition () and at least one second phosphorescent composition (), the first and second compositions being simultaneously excitable by a predefined illuminant from a single first surface () of the structure, the security structure () being provided in the form of a security thread, a security film, or a patch, wherein the first fluorescent composition is at least partially stacked on the second phosphorescent composition and/or the first and second compositions are used for the reference marking on the security structure.

Security structure including phosphorescent and fluorescent compositions

A method of authenticating and/or identifying a security article including a first image includes superimposing at least partially the first image of the article with a second image. The second image may be produced by an electronic imager. The method further includes performing a relative movement between the first and second images so as to make it possible to observe an item of information relating to authentication and/or identification of the security article during the relative movement between the first and second images.

Method of authenticating and/or identifying a security article

The invention relates to a sheet of a given size, having a rear face and a front face. The invention is characterised in that it includes at least one part which is made from fibrous material and at least one other part which is made from plastic material and which is adjacent to the fibrous part, said parts being joined at a zone in which the two materials overlap. The plastic part at least partially forms a side zone of the sheet that is free of fibrous material and the plastic part includes at least one transparent or translucent zone.

Hybrid sheet, such as a security sheet, formed by assembling a fibrous part and a plastic part

A method for authenticating and/or identifying a security article that includes a transparent or translucent substrate and, on a side of a first face of the substrate, a first image. The method includes superimposing at least partially the first image of the article with a second image. The second image may be produced by an electronic imager. The second image may be situated on the side of a second face of the substrate that is opposite to the first face. The method permits observation of an authentication and/or identification information item of the security article during a change of the angle of observation of the first and second superimposed images.

Method for the authentication and/or identification of a security item

The invention relates to a security paper consisting of at least two paper fiber webs, wherein the first web is embodied in the form of an external we provided with at least one authentication element and the second web comprises a reinforcing element which is substantially absent in the first web and selected amongst materials improving mechanical strength, and/or another authentication element and the authentication element of said first web substantially absent in the second web. A method for producing the inventive security paper is also disclosed.

Multi-layer security paper

The present invention relates to a sheet material () comprising at least one first layer defining an outer surface of the sheet material and having at least one first color, at least one second layer comprising at least one watermark () and having at least one second color, the first and second colors having at least different saturations and/or hue angles.

Sheet material comprising at least one watermark having a colored shade

The invention relates to an information carrier intended to be handled relatively frequently, characterized in that it contains at least one biocidal agent. This information carrier is in particular intended for the production of a banknote, of a passport, of a playing card, of a packaging, of a book or of a magazine. The invention also relates to the process for producing said information carrier, characterized in that at least one biocidal agent is incorporated into a basic carrier made of cellulosic and/or plastic materials.

Data medium having biocidal properties and method for making same

The invention relates to a coated sheet of security paper which includes security elements and has a high print rendition and a high resistance to circulation, which sheet is characterized in that at least one of its sides is coated with a transparent or translucent coating comprising at least one colloidal silica and at least one transparent or translucent elastomeric binder. In particular, the binder is a polyurethane. The invention also relates to the process for manufacturing the said sheet and to a banknote obtained from this sheet.

Security sheet comprising a transparent or translucent layer

The invention concerns a sheet material, characterized in that it incorporates at least one knitted structure. The invention also concerns a document and a base fabric comprising said sheet material, as well as a method for making said material. The invention further concerns a knitted structure comprising at least one authenticating and/or identifying element, as well as a method for authenticating and/or identifying a document or a knitted structure.

Knitted structure designed to be incorporated in a sheet material

An optical structure comprising first and second opposite outside faces, at least a first interface comprising a first screen of microreliefs and arranged in such a manner that travel through the first interface from the first outside face towards the second outside face, passes from a first medium having a first refractive index to a second medium having a second refractive index that is greater than the first, and at least one second interface comprising a second screen of microreliefs and arranged in such a manner that travel through the second interface from the first outside face towards the second outside face, passes from a third medium having a third refractive index to a fourth medium having a fourth refractive index less than the third.

Optical structure, in particular for a security document and/or a document of value

The present invention relates to a security film comprising a fibrous substrate incorporated at least partially in which is a security strip that comprises at least one security element and that extends between two edges of said fibrous substrate, said security strip being made of paper and comprising an adhesive.
