    • 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).

    • Disclosed is a security document (11) having at least one paper ply (4) that is covered on both sides with a transparent plastic layer (2, 13). Disclosed is also a jacket made of transparent synthetic material, which can be used to produce said security document (11). Substantial increase in security, particularly in the production and issuance of said security document (11), can be achieved due to the fact that the paper ply (4) is a security paper with at least one security characteristic (5, 8, 10, 15, 16) and the plastic layers (2, 13) are a sleeve made of thermoplastic material that is molten into a transparent sleeve (13) by applying only high pressure and/or temperature, wherein an edge area (14) is available at least in certain segments, in which the plastic layers (2, 13) are directly adjacent to one another and wherein at least one of the plastic layers has at least one security characteristic (3, 7).
    • 公开了一种具有至少一个纸层(4)的安全证件(11),其两侧用透明塑料层(2,13)覆盖。 公开了一种由透明合成材料制成的护套,其可用于生产所述安全证件(11)。 由于纸层(4)是具有至少一种安全特性的安全文件(5,8,10),所以安全性的显着增加,特别是在生产和发行所述安全文件(11)时可以<实现< ,15,16),并且塑料层(2,13)是由热塑性材料制成的套筒,其通过仅施加高压和/或温度而熔化成透明套筒(13),其中边缘区域(14)可用 至少在某些段中,其中塑料层(2,13)彼此直接相邻,并且其中至少一个塑料层具有至少一个安全特性(3,7)。
