Abstract

The method comprises the incorporation to the security paper itself of a series of indicia, which may be letters, anagrams, etc., obtained from an water resistant ink with which the corresponding printing is achieved on an 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 or phosphorescent pigments for identification of the indicia with ultraviolet light or by transparency, and optionally also magnetic materials or simply metal materials for detection of the indicia by means of a magnetic field.

Description

PROCEDIMIENTO DE OBTENCIÓN DE PAPEL DE SEGURIDAD Y PAPEL DE SEGURIDAD OBTENIDO CON DICHO PROCEDIMIENTO  PROCEDURE FOR OBTAINING SECURITY PAPER AND SECURITY PAPER OBTAINED WITH THIS PROCEDURE

D E S CR I P C I Ó N D E S CR I P C I Ó N

OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION

La presente invención se refiere a un procedimiento de obtención de papel de seguridad, procedimiento cuyo objetivo es conseguir potenciar el grado de seguridad de este tipo de papel frente a posibles falsificaciones, siendo de especial aplicación en el ámbito del papel moneda así como en la obtención de cualquier otro tipo de documento para el que se requiera de un papel con unas prestaciones similares. The present invention relates to a procedure for obtaining security paper, a procedure whose objective is to enhance the degree of security of this type of paper against possible counterfeiting, being of special application in the field of paper money as well as in obtaining of any other type of document for which a paper with similar benefits is required.

La invención concierne también al papel de seguridad obtenido con dicho procedimiento. ANTECEDENTES DE LA INVENCIÓN The invention also concerns the security paper obtained with said method. BACKGROUND OF THE INVENTION

Obviamente el nivel de seguridad ofrecido por un papel de este tipo se corresponde con la dificultad de fabricación del mismo, o lo que es lo mismo, con la dificultad que ofrece a su falsificación. Obviously the level of security offered by a paper of this type corresponds to the difficulty of manufacturing it, or what is the same, with the difficulty it offers to its falsification.

En esta línea y además de las clásicas marcas de agua, visibles por transparencia, es conocida y comúnmente utilizada la incorporación a la masa de papel de planchettes o fibrillas de seguridad, los primeros visibles microimpresos o no y de un material luminiscente o iridiscente, y las segundas visibles o invisibles, y fluorescentes a la luz ultravioleta, que en uno y otro caso se distribuyen arbitraria o desordenadamente en la superficie del documento. También es conocida la utilización de láminas o hilos de material plástico o de naturaleza metálica, incorporar tratamientos que les confieren propiedades ópticas o propiedades capaces de ser analizadas mediante sensores adecuados que se aportan al papel durante la fase de conformación laminar del mismo, quedando rodeados de fibras celulósicas, lo que por un lado supone una absoluta imposibilidad de extracción de dichos hilos sin que se produzca rotura del papel, con la consecuente evidenciación de que el documento ha sido manipulado, y sin que sea posible su posterior introducción en otro papel, para conferir a este último un aspecto de autenticidad, ya que tan sólo en la máquina de papel y durante la fase de formación de la hoja, se está en condiciones de introducir el hilo en el interior de la masa celulósica. In this line and in addition to the classic watermarks, visible for transparency, it is known and commonly used the incorporation into the mass of paper of planchettes or safety fibrils, the first visible microprinted or not and of a luminescent or iridescent material, and the second visible or invisible, and fluorescent in ultraviolet light, which in either case are distributed arbitrarily or messily on the surface of the document. It is also known to use sheets or threads of plastic material or of a metallic nature, to incorporate treatments that give them optical properties or properties capable of being analyzed by suitable sensors that are contributed to the paper during the laminar conformation phase, being surrounded by cellulosic fibers, which on the one hand implies an absolute impossibility of extracting said threads without causing paper breakage, with the consequent evidence that the document has been manipulated, and without its subsequent introduction into another paper, to confer on the latter an aspect of authenticity, since only in the paper machine and during the sheet formation phase, it is in a position to introduce the thread into the cellulose mass.

Como también es sabido, estos elementos de seguridad pueden ser unitaria y aisladamente aportados al papel, pero generalmente son utilizados en combinación. As is also known, these security elements can be unitary and isolated in paper, but they are generally used in combination.

DESCRIPCIÓN DE LA INVENCION El procedimiento de obtención de papel de seguridad que la invención propone, y más concretamente el papel obtenido con dicho procedimiento, constituye una nueva alternativa en este campo, que permite la utilización de nuevos medios de "personalización" del papel, también utilizables aisladamente pero preferentemente en combinación con los anteriormente citados. DESCRIPTION OF THE INVENTION The procedure for obtaining security paper that the invention proposes, and more specifically the paper obtained with said procedure, constitutes a new alternative in this field, which allows the use of new means of "personalization" of the paper, also usable in isolation but preferably in combination with those mentioned above.

De forma más concreta el procedimiento que se preconiza parte de la utilización como materias primas, además del ineludible papel, obtenido por cualquier medio convencional apropiado, de una tinta resistente al agua y de un soporte soluble en agua. De forma más concreta y con la tinta resistente al agua se procede a la impresión de cualquier tipo de signos, tales como letras, anagramas, etc., sobre el citado soporte soluble en agua. Tras la obtención de estos signos convenientemente impresos sobre el citado soporte, éste se introduce en agua o en un líquido de base acuosa, durante el tiempo necesario para que se produzca la disolución del mismo, quedando los signos en suspensión y en condiciones de ser aportados al papel de seguridad, en una tercera y última fase operativa y de forma similar a como se incorporan convencionalmente a dicho papel los planchettes o las fibrillas de seguridad. Complementariamente y como otra de las características de la invención, la tinta a partir de la que se obtienen los signos puede incorporar pigmentos fluorescentes, así como también materiales magnéticos, en función del posterior sistema de detección de dichos signos para verificación del documento. More specifically the procedure that is recommended as part of the use as raw materials, in addition to the inescapable paper, obtained by any appropriate conventional means, of a water-resistant ink and a water-soluble support. More specifically and with water-resistant ink, any type of signs, such as letters, anagrams, etc., are printed on said water-soluble support. After obtaining these conveniently printed signs on said support, it is introduced into water or an aqueous-based liquid, for the time necessary for its dissolution to occur, leaving the signs in suspension and in conditions of being provided. to the security paper, in a third and last operative phase and in a similar way to the way conventionally incorporated into said paper the planchettes or the safety fibrils. Complementarily and as another characteristic of the invention, the ink from which the signs are obtained can incorporate fluorescent pigments, as well as magnetic materials, depending on the subsequent detection system of said signs for document verification.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION

De forma más concreta y para la puesta en práctica del procedimiento que se preconiza, como tinta de impresión debe utilizarse tinta insoluble en agua basada por ejemplo en un polímero acrílico o de estireno butadieno, o polímero epoxi, o también acrilonitrilo, o cualquier otro que consiga la insolubilidad en agua, tinta, que, como anteriormente se ha dicho, puede incor porar pigmentos fluorescentes o fosforescentes, preferentemente de colores vivos. More specifically and for the implementation of the procedure that is recommended, as a printing ink, water-insoluble ink based on, for example, an acrylic or styrene butadiene polymer, or epoxy polymer, or acrylonitrile polymer, or any other which get insolubility in water, ink, which, as previously stated, can incorporate For fluorescent or phosphorescent pigments, preferably brightly colored.

Estos signos pueden ser letras o anagramas de cualquier tipo, pero preferentemente estarán conceptualmente relacionados con el emisor del documento. These signs may be letters or anagrams of any kind, but preferably they will be conceptually related to the issuer of the document.

En este sentido y a título meramente ejemplario, cuando se trate de papel moneda los citados signos pueden hacer alusión, de cualquier forma, al país de origen o papel emisor de dicha moneda y de análoga manera a la entidad emisora de un documento, cuando a su vez se trate de este tipo de vapor. In this sense and for purely exemplary purposes, in the case of paper money, the aforementioned signs may refer, in any way, to the country of origin or paper issuing said currency and similarly to the issuing entity of a document, when Once this type of steam is involved.

Com soporte para impres ión de la tinta , c&ncretamente como soporte soluble al agua , se ha previsto la utilización de alcohol de polivinilo o mezclas de otros polímeros solubles . With the support for printing the ink, specifically as a water soluble support, the use of polyvinyl alcohol or mixtures of other soluble polymers is envisaged.

Tras la disolución del soporte y la aportación de los signos al papel de seguridad propiamente dicho , tales signos quedan flotando en la masa de papel recién formada y , debido a sus especiales características ópticas , son reconocibles en el papel seco mediante el concurso de una luz ultravioleta por reflexión, o con una luz normal por transparencia , encontrándose por tanto en posición "latente" en el interior del papel hasta su inspección por los medios ópticos anteriormente citados . After the dissolution of the support and the contribution of the signs to the security paper itself, such signs remain floating in the mass of newly formed paper and, due to their special optical characteristics, they are recognizable in the dry paper by means of the contest of a light ultraviolet by reflection, or with a normal light for transparency, therefore being in a "latent" position inside the paper until inspection by the optical means mentioned above.

Como también se ha apuntado anteriormente, los signos pueden incorporar materiales magnéticos o simplemente metálicos, siendo consecuentemente susceptibles de reconocimiento en el seno de un campo magnético. Debido a que tales signos están formados de un material fIexible, por la composición de la tinta al introducese la lamina de papel constitutiva del documento de que se trate, no están sometidos a ninguna tensión y no perturban los procedimientos de impresión, siendo compatible con cualquier otra seguridad conocida. As also noted above, the signs may incorporate magnetic or simply metallic materials, being consequently susceptible to recognition within a magnetic field. Because such signs are formed of a flexible material, by the composition of the ink when the sheet of paper constituting the document in question is introduced, they are not subjected to any tension and do not disturb the printing procedures, being compatible with any Other known security.

Por su sistema de producción por técnicas de impresión y su fácil incorporación al papel con los sistemas ya existentes, es sumamente fácil conseguir personalizaciones distintas, como ya se ha apuntado anteriormente, no sólo para cada usuario o consumidor del papel, sino también para cada tipo de labor fabricada. No se considera necesario hacer más extensa esta descripción para que cualquier experto en la materia comprenda el alcance de la invención y las ventajas que de la misma se derivan. Due to its production system by printing techniques and its easy incorporation into paper with existing systems, it is extremely easy to achieve different customizations, as already noted above, not only for each user or consumer of the paper, but also for each type of manufactured work. It is not considered necessary to make this description more extensive so that any person skilled in the art understands the scope of the invention and the advantages derived therefrom.

Los términos en que se ha redactado esta memoria deberán ser tomados siempre en sentido amplio y no limitativo. The terms in which this report has been written must always be taken in a broad and non-limiting sense.
