The present invention relates to a laminated structure (8) for an e-document (1) that comprises a first substrate layer (10) defining at least two planar flaps (5, 6) connected by at least one folding line (14): the first flap (5) supporting an antenna (12) and a microcircuit device (11) enabling contactless data exchange; the second flap (6) supporting an electromagnetic disturbance element (13) placed relative to the microcircuit device so as to inhibit the contactless reading and/or writing by the microcircuit device in at least one folded configuration of the structure (8), a) the structure (8) comprising at least one layer of a heat-activatable or pressure-sensitive adhesive making it possible to receive, at least partially in the body thereof, the microcircuit device and/or the antenna and/or the electromagnetic disturbance element, and/or b) the flaps having at least one adhesive layer and/or a fibrous layer (15, 16) and/or a polymer layer having a different thickness for each of the flaps.
The present invention relates to a security element having a variable optical effect, characterized in that it comprises at least one quasi-spherical particle (10) having at least one external part (11) and at least one internal part (12), said external part (11) comprising at least one cholesteric liquid crystal and said internal part (12) comprising at least one thermochromic compound and/or at least one photochromic compound undergoing a reversible transition from a colourless state to a dark colour or from a dark colour to a colourless state when said compound is subjected to an activation temperature or to activation radiation respectively, the dark colour making it possible to see the interference effect of said liquid crystal, and the colourless state making this interference effect no longer visible.

METHOD FOR PRODUCING A SHEET WITH A THICK OR THIN SECTION AT THE LEVEL OF A RIBBON AND CORRESPONDING SHEET
The invention relates to a paper-making method for producing a sheet (1) with at least one jet of a fibrous substrate (2) and at least one fibrous ribbon (3), wherein the ribbon (3) is introduced into a fibrous suspension in a round paper machine permitting formation of the jet or in direct contact with the round shape or in contact with the jet formed, the point of introduction of the ribbon (3) is selected such as to create at least one thin section or a thick section on the sheet (1) at the level of the ribbon (3), the thin section being due to a reduction in the draining of the fibrous suspension by the ribbon (3).

SECURITY SHEET WITH A RIBBON HAVING A ZONE OF REDUCED OPACITY
The invention relates to a sheet (1) comprising a fibrous substrate (2) and at least eon ribbon (3) defining at least one zone of reduced opacity (4), the sheet (1) having at least two complementary security elements (5, 6) situated respectively to either side of said at least one ribbon (3) the whole of which may be transparently viewed due to the zone of reduced opacity (4).
The invention relates to a security sheet that comprises an information to be exposed and a preferably fibrous substrate in which is preferably totally embedded a ribbon that has a surface A and a surface B and is strippable along the surface B thereof, the information to be exposed being carried by and/or opposite the surface B of the ribbon. The invention also relates to a method for making said security sheet, and to a security document or article including such a sheet.
A method of reading at least one bar code carried by a substrate, the method including: a) generating, especially in an automatic manner, when presenting the bar code to a system for reading the bar code, at least one authentication cue related to an intrinsic physical characteristic of the substrate and independent of the data contained in the bar code, and b) allowing the reading of the bar code, only in the event of a positive authentication of the substrate or reading the bar code regardless of the result of the authentication of the substrate and in the event of negative authentication of the substrate, preventing access to just one part of the data contained in the bar code and/or to any data that may be associated with the bar code, and which is stored on a separate data medium from the substrate.
