The present application relates to a multilayer card (1) comprising a fibrous outer layer (2; 2A; 2B), the fibrous outer layer (2; 2A; 2B) comprising: relative to the total weight of the fibrous outer layer (2; 2A; 2B), 55 wt % to 80 wt % of natural fibres, preferably 60 wt % to 65 wt %; relative to the total weight of the fibrous outer layer (2; 2A; 2B), 3 wt % to 10 wt % of synthetic fibres, preferably 4 wt % to 8 wt %; relative to the total weight of the fibrous outer layer (2; 2A; 2B), 9 wt % to 20 wt % of inorganic fillers, preferably 12 wt % to 16 wt %; a binder, in particular a mixture of PVA and starch or a latex, preferably selected from among acrylic, styrene-butadiene or butadiene latexes; and a softener, in particular glycerine, urea, sodium nitrate, or the mixtures thereof, the fibrous outer layer (2; 2 A; 2B) being printed upon and/or comprising a security element, which is in particular luminescent.
摘要:
The invention relates to a flat insert intended for being inserted in a security document, which includes a fibrous substrate (2) formed as a single layer having a cavity (5) and an electronic device (3) having contactless communication, housed in said cavity. Said cavity is in communication with a single surface of the fibrous substrate (2) and includes, in the cross-section thereof, a peripheral shoulder (13) for housing said electronic device in said cavity without generating a thickened portion of the insert, said fibrous substrate (2) including synthetic fibres.
摘要:
The present invention concerns a structure (10) that is customisable by thermal transfer printing, in particular D2T2 or re-transfer, in particular for a multi-layer secure card structure, the customisable structure comprising: -a layer (12) of a non-opaque material for receiving thermal transfer printing, preferably comprising a vinyl polymer, in particular non-halogenated, more advantageously a polyvinyl ester, and more preferably still polyvinyl acetate (PVAc), -a fibrous paper sub-layer (11), comprising at least one security element (13) incorporated into the paper and/or arranged on the surface of the fibrous sub-layer.
摘要:
The present invention relates to a sheet element capable of being engraved by a laser, comprising a fibrous substrate that comprises: natural fibres, in particular cellulose fibres; dispersed in the body of the fibrous substrate, at least one laser-marking pigment, in particular at least one metal oxide; at least on the surface of the fibrous substrate, and preferably in the body thereof, a printability filler, in particular one selected from among inorganic particles; and, preferably, at least one binder dispersed in the body of the fibrous substrate.
摘要:
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.
摘要:
The invention relates to a method for producing a support (100) containing at least one electronic device (50), said support comprising at least one fibrous layer (10) of paper or non-woven material including at least 15 % mass of synthetic fibres. Said method comprises a step of introducing the electronic device (50), by means of a grip-release tool, at a site on said fibrous layer (10), that does not contain a cavity, by compressing said fibrous layer (10) such that, once the electronic device (50) has been introduced, it is received in the support (100) without generating any increased thickness.
摘要:
The invention relates to a method for producing a support comprising at least one electronic device (6), according to which the electronic device (6) is introduced, by means of a grip-release tool, into a first layer (2) of the support, made from at least one polymer material.
摘要:
The invention relates to a method for making a security document comprising a fibrous material shaped in a paper machine, in which a security element (1) is incorporated into the security document, said method comprising a step consisting of treating the security element (1) in-line at atmospheric pressure with a plasma discharge (2) just before the security element is incorporated into the fibrous material or transferred onto a sheet exiting the paper machine.
