The invention relates to a multiple layer laminate such as a printing carrier, especially in the form of antifalsification paper such as bank notes. Said multiple layer laminate or more precisely the printing carrier comprises at least one plastic layer (22) having an upper side (20) and a lower side (21), an upper paper layer (11) which is connected to the upper side (20) of the plastic layer (22), and optionally a lower paper layer (12) which is connected to the lower side (21) of the plastic layer (22). The aim of the invention is to achieve an especially intimate connection between the individual layers, with simultaneously good printability and with similar haptic characteristics such as those of pure paper carriers. To this end, a thermoplastic polymer material is used as the plastic layer (22), and the connection between the paper layers (11, 12) and the plastic layer (22) is ensured, essentially without additional bonding agents, by means of penetration regions (13, 14) in which parts of the plastic layer (22) are melted with the mass of fibre composite of the paper layers (11, 12). To this end, the penetration regions (13, 14) essentially do not extend to the surfaces of the paper layers opposing the plastic layer (22).

A phosphor (photo-luminescent) material based authentication system in which a blend (mixture) of at least two, preferably three or more, phosphor materials are used as a photo-luminescent security marking which is applied to or incorporated within an article / document to be authenticated. Preferably, the phosphor materials are each excitable by “eye safe” excitation radiation comprising visible light of wavelength 380 nm to 780 nm. Moreover, when excited the security marking preferably also emits visible light thereby minimizing any risk of damage to an operator's eye in the event of accidental exposure to the excitation radiation and / or light generated by the photo-luminescent marking. The authenticity of the article / document can be authenticated by verification of the composition of the phosphor by exciting the marking and comparing one or more selected parameters of light emitted by the security marking with corresponding parameters of the characteristic emission spectrum of the authentic phosphor blend.

When it is intended that a hologram foil is adhered to a metal pattern, a general-purpose hot-melt adhesive is inferior in an adhesion property to a metal surface and, accordingly, fixing of the hologram foil itself is difficult and, even when such fixing is achieved, a problem of peeling-off, dropping-off or the like of the hologram foil is generated. These problems are solved by forming a primer layer on a surface of the metal pattern and, thereafter, a metal foil having a design such as a hologram foil is fixed through a hot-melt adhesive.
