Definitions

• Multilayer card having a fibrous outer layer
• the present invention relates to the field of multilayer cards and more particularly to multilayer cards of the credit card, social security card or identity card type, comprising one or more security elements.
• multilayer structures comprising a layer of paper are known from the following documents.
• WO 2009/007659 describes an insert comprising a chip module and a wire antenna.
• the module opens on the outer surface of the insert.
• Said insert being intended to be integrated in a passport or an identity card, it constitutes an inner layer which is therefore not intended to be printed.
• WO 2006/101493 discloses a multilayer structure comprising a printable layer including synthetic paper type Teslin ® .
• the multilayer structure further comprises an intermediate layer comprising a thermosetting polymer and a base layer on the surface of which electronic components are deposited.
• Teslin ® is a plastic material that is neither fibrous nor cellulosic. This multilayer structure may be printable inkjet but its resistance to successive bends may not be entirely satisfactory.
• WO 2006/077339 discloses paper layers loaded with synthetic fibers to enhance their internal cohesion.
• the present invention aims to meet all or part of the aforementioned needs.
• the invention relates to a multilayer card comprising a fibrous outer layer, the fibrous outer layer comprising at least:
• mineral fillers in a mass content of between 9 and 20%, preferably between 12 and 16%, relative to the total weight of the fibrous outer layer,
• a binder especially a mixture of PVA and of starch or a latex, preferably chosen from acrylic, styrene-butadiene or butadiene latexes, and
• a softening agent in particular glycerol, urea, sodium nitrate or a mixture thereof,
• the outer fibrous layer being printed and / or comprising a security element, in particular a luminescent element.
• the chip advantageously does not open onto the outer surface of the fibrous outer layer.
• the triple combination of synthetic fibers, a binder as well as a softening agent advantageously makes it possible to give the outer fibrous layer improved elasticity, flexibility and double-fold resistance properties.
• the presence of mineral fillers advantageously makes it possible to give the fibrous outer layer printability properties, in particular offset and inkjet printability.
• the printing of the fibrous outer layer may consist of a variable mention, for example the name or the photograph of the holder of the multilayer card according to the invention.
• All or part of the printing and / or the security element of the outer fibrous layer may be visible.
• at least part of the printing and / or the security element of the fibrous outer layer of a multilayer card according to the invention may be visible to a user of said multilayer card.
• the resolution of the printing of the fibrous outer layer may be greater than 600 dpi.
• the natural fibers may be present in the fibrous outer layer in the form of a mixture of long natural fibers (derived from softwood) and short natural fibers (from hardwood).
• Long natural fibers may, for example, be used to improve mechanical strength and short natural fibers may, for example, be used to impart opacity.
• the mass proportion of short natural fibers within the fibrous outer layer may be less than or equal to the mass proportion of long natural fibers.
• at least 50% by weight of the natural fibers can be long natural fibers.
• at least 80% by weight of the natural fibers are long natural fibers.
• the natural fibers may be formed in whole or in part of cellulosic fibers, in particular all of them being cellulosic fibers.
• the synthetic fibers may, for example, be chosen from rayon fibers, in particular fibran or viscose, or from a thermoplastic material, in particular a polyamide, a polyester, a polyolefin and / or a mixture of such fibers.
• the mass content of synthetic fibers in the fibrous outer layer can be evaluated, for example, by three-dimensional measurement by two-dimensional cross-section stereology using a scanning electron microscope.
