Abstract (en)
[origin: FR2861101A1] Multi-web security paper is made from at least two fibre webs - a first, outer web containing an authentification element such as a watermark, irridescent particles, fluorescent, phosphorescent or coloured fibres or particles and a second web containing a reinforcing and/or authentification element. Multi-web security paper is made from at least two fibre webs - a first, outer web containing an authentification element such as a watermark, irridescent particles, fluorescent, phosphorescent or coloured fibres or particles and a second web containing a reinforcing and/or authentification element. The second web's reinforcing element is not present in the first web, and the authentification element of the first web is not present in the second one, which is thicker than the other webs and preferably twice as thick. The authentification element in the first, and optionally the second, web is detectable by optical means or responds to certain stimuli, such as an electromagnetic and preferably microwave field, by giving out a detectable signal. The reinforcement can be provided by natural or synthetic fibres.
