Abstract
METHOD FOR OBTAINING SECURITY PAPER
AND SECURITY PAPER OBTAINED BY SUCH METHOD
ABSTRACT
The method comprises the incorporation to the security paper itself of a series of indicia, which may be letters, anagrams, etc., obtained from a water resistant ink with which the corresponding printing is achieved on a water soluble medium, so that after said printing, the medium is eliminated and the indicia remain in suspension and may be applied to the paper in the same way as are incorporated to such paper the conventional security planchettes or fibrilles. Said paper web also incorporates Fluorescent For phosphorescent pigments for identification of the indicia with ultraviolet light or by transparency, and optionally also magnetic materials or simply metal materials for detecion of the indicia by means of a magnetic field.

Description
NETHOD ~OR OBTAINING SECURITY P~PER 2 0 78 ~ 0 2 A~D SEC~RITY PAPER OBT~INED BY ~CH ~T~OD
S P E c I F I c A T I o N
OBJECT OF THE INVENTION
The present invention relates to a method for obtaining security paper, the said method being aimed at ~uccessfully enhancing the extent of security o~ this kind of paper from potential coun~erfeits, the same being specifically applicable to the ~ield of paper money and to obtaining any ~th~r kind of document re~uiring a paper with like benefiks.
The invention also relat~s to the security paper the said method yields.
BACRGROUND OF T~ INV~NTIO~
The extent of security that paper of this kind a~fords-is obviously a reflection of how di~icult it is to manufacture the same, or in other words how difficult it i~ to counterfeit the ~ame. ~ ~ .
In this sense and in addition to the c~assi~al watermark~, visible by transparency, a well-known and widespread practice is to provide the paper mass with security pIanchettes or fibrilles, the first visible micropri~ted or otherwise, and with luminescent or iridescent material, and the latter visible or invisible, and fluorescent under ultraviolet light, in both cas s distributed in an arbitrary or disorderly manner upon the surface of the document.
ThP u6e of sheets or yarns o~ pla~tic or metallic material is also knwnl that can even be treated to carry optical properties or properties capable of being analyzed by suitable sensors, added to the paper at the sheet ~ormation stage, th~

~78~02 ~ame being ~nclosed in cellulose ~ibres, thereby on the one hand rendering it almost impossible to remove the said yarns without tearing the paper, hence revealing that the document has been manipulated, and on the other preventing them from being i~serted in other paper to make the latter seem genuine, for the yarn is only in a position to be inserted into the cellulose ma~s when in the paper machine and at the sheet formation stage.
It is also a known fact that these security elements can be contributed to the paper in a unitary and isolated manner, though thsy are generall.y used in combination.
DESCRIP~ION OF ~E INVENTIO~
The method for obtaining security paper subject of the invention, and more specifically the paper the said method yields, tands as a new alternative in this ~ield~ allowing the n~w means to be used to ~Ipersonalize~ the paper, be it on their own ox preferably together with the a~oresaid means.
~ ore specifically the method subject hereof relies on the use of raw materials, naturally besides paper that i~ obtained by any suitable conventional means, namely a water resistant ink and a water soluble ~edium.
More specifically, the water resistant ink is used for prinking any manner of indicia, such as l~tters, anagrams and so forth, upon the said water soluble medium.
After obtaining the said indicia, suitably printed upon the caid medium, the latter is left in water or an aqueous liquid for as long as it requires to be dissolved, whereupon the indicia remain in suspension and ready to be incorporated to the security pap~r, at a third and final operative stage, and in a manner similar to how the security planchettes or the fibrilles are conventionally incorporated to the said paper.

DESCRIP~ION OF ~E INVENTIO~
The method for obtaining security paper subject of the invention, and more specifically the paper the said method yields, tands as a new alternative in this ~ield~ allowing the n~w means to be used to ~Ipersonalize~ the paper, be it on their own ox preferably together with the a~oresaid means.
~ ore specifically the method subject hereof relies on the use of raw materials, naturally besides paper that i~ obtained by any suitable conventional means, namely a water resistant ink and a water soluble ~edium.
More specifically, the water resistant ink is used for prinking any manner of indicia, such as l~tters, anagrams and so forth, upon the said water soluble medium.
After obtaining the said indicia, suitably printed upon the caid medium, the latter is left in water or an aqueous liquid for as long as it requires to be dissolved, whereupon the indicia remain in suspension and ready to be incorporated to the security pap~r, at a third and final operative stage, and in a manner similar to how the security planchettes or the fibrilles are conventionally incorporated to the said paper.
-- ~ ;
2~7~2 Furthermore, another characteristic of the invention provides for the ink used to obtain the indicia to contain fluorescent or phosphorescent pigments, and also magnetic materials, depending upon the sy~tem to be subsequently employed in detecting such indicia and verifying the document.
PREFE~RED E~BODINENT OF ~EE INV~NTIO~
More specifically, in practice the printing ink used in the method ~ubject hereof must be insoluble in water, for instance based upon an acrylic polymer, or styrene, butadiene, or epoxy polymer or also acrylonitrile, or such others as provide insolubility in water, which ink can as aforesaid be provided with fluorescent or phosphorescent pigmentsj preferably briyhtly coloured~
Such indicia can be letters or anagrams of any kind, but shall preferably be conceptually related to the issuer of the document.
In this sense, and in token only of example, in ~he case of paper money, the said indicia can in one way or another refer to the country of origin or issue of the said currency and similarly to the institution issuing a do ument, if the latter ls in turn the case.
The medium envisaged to print the ink, specifically as a wat~r soluble medium, is provided as polyvinyl alcohol or mixtures of other soluble pol~mers.
After solving the med1um and incorporating the indicia to the ~ecurity paper as such, tne said indicia remain floating upon the ready-formed paper mass and, given the special optical characteri~tics thereof, they can be rQcognised on the dry paper with the assistance of an ultraviolet light by reflection, or under normal light by transparency, the same hence lying "latent"
. ~ . .
,. ~
o2~78~
within the paper until inspected using the aforesaid optical means.
As also mentioned hereinbefore, the indicia can carry magnetic or simply metal materials, and can hence be recognised within a magnetic field.
Given that the said indicia are made of a flexible material, given the composition of the ink, on being inserted in the ~heet of paper making up the document in question, the same are subjected to no tension what~oever and do not di6rupt the printing method , and are compatible with any other Xnown security.
As they are produced using printing techniques and can be sasily incorporated to the paper with systems that already exi~t, it is extremely easy to obtain different personalization~, as aforQsaid, not only for each user or consumer of the paper, but for every kind of manufactured work.
We feel that the device has now been suf~ici2ntly describ~d ~or any expert in the art to have grasped the full scope of the invention and the advantages it offers.
The material~, shape, size and layout of the ~lements may altered provided that this entails no modification of the essential features of the invention.
The terms used to describe the i~vention herein should be taken to have a broad rather than a restrictive aeaning.
