Security paper or special paper incorporating high resistance synthetic elements and a procedure for obtaining said papers

Abstract

It consists in performing a security paper or special paper incorporating pigments within the paste of the synthetic element itself during its manufacture, providing pigment properties to said synthetic element, the pigments being protected from the attack of physical and chemical agents by the synthetic element itself.

Description

OBJECT OF THE INVENTION[0001]The object of the present invention refers to a security or special paper that incorporates high resistance synthetic elements (fibres, microspheres, . . . ), as well as a security document manufactured with said support.[0002]These synthetic elements incorporated in the security paper or special paper are usually provided different qualities such as been fluorescent, phosphorescent, luminescent, with magnetic characteristics, etc, characteristics that are visible to the naked eye all that can be observed under certain conditions, such as under ultraviolet light, magnetic sensors, etc[0003]The synthetic elements incorporated by the security paper or special paper proposed by the invention provide that such characteristics conferred to these elements are embedded within them, such that the loss of properties inherent to these elements becomes more difficult as time goes by, resisting the harsh conditions that security and special documents are subject to,...

AI Technical Summary

Benefits of technology

[0003]The synthetic elements incorporated by the security paper or special paper proposed by the invention provide that such characteristics conferred to these elements are embedded within them, such that the loss of properties inherent to these elements becomes more difficult as time goes by, resisting the harsh conditions that security and special documents are subject to, such as bank notes or the like.

Problems solved by technology

It has been demonstrated that superficially arranged pigments lose their features prematurely since light deteriorates their properties very easily, since there are only protected by the possible fibres in the paper.

Moreover, since these pigments remain on the surface they can easily deteriorate by friction or the use given to the security paper they are on.

It has thus been demonstrated that security papers integrating elements with fluorescence, phosphorescence, luminescence, and other features lose such qualities with use, making these authentication and recognition measures practically useless for such security documents.
