Definitions

  • 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.
  • 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
  • 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.
  • the fibre manufacturing procedure is generally performed by obtaining extremely fine filaments in an extrusion line that are cut to a certain length.
  • Certain pigments are added to this type of elements to confer them the desired characteristics of fluorescence, phosphorescence, luminescence, magnetism etc, these pigments being applied after manufacturing said fibres, such said fibres are superficially impregnated.
  • the pigments usually used can basically be of two types, inorganic-based pigments are the main characteristic of which is offering good resistance to preserve the fluorescent, phosphorescent, luminescent, magnetic, and other properties, although in contrast they offer deficient response intensity.
  • the second type of pigments that can be used organic-based pigments and have bad resistance, the effects lasting little, but however, offering good response intensity.
  • the synthetic element impregnation procedure provides introducing these inside pressure tanks, until they are totally dyed by the pigments.
  • a security paper or special paper which, based on the previously mentioned technology, internally incorporates synthetic elements that are provided with pigments, either fluorescent, phosphorescent, luminescent, magnetic, etc., that confer them security features, that such pigments are highly resistant to the detachment of their own synthetic elements and that they can be easily integrated in the manufacturing process of a security paper or special paper used to manufacture security documents or special documents such as banknotes, bills of exchange, security labels, etc.
  • the object of the invention is an improved procedure for incorporating said synthetic elements in the paper forming process, preventing their caking and therefore favouring their dispersion and integration in the paper paste.
  • the pigment introduced in the paste for forming the synthetic element will be protected by the material of the element itself, preventing wear by friction and being protected from attacks from physical and chemical agents that the security document may suffer and from light, so that the features incorporated in the pigments are kept unchanged with time.
  • the material of these synthetic elements that allows integrating the pigments in the paste without their deterioration in is not viscous or polyamide but polypropylene, and has the difficulty of being a material without hydrogen free radicals and is therefore a product that is not related to the water surrounding it, that is, it is not impregnated in the water of the aqueous solution it is in, producing caking of the synthetic elements and therefore not providing a homogeneous dispersion thereof in the water.
  • aqueous solution has been achieved in which the synthetic elements are dispersed without caking, with the addition of dispersing and/or penetrating and/or antifoaming agents in the appropriate proportion. This allows them to be incorporated in the aqueous paper forming solution, achieving the homogenous dispersion of such synthetic elements inside the paste of the paper that is being formed, preventing the caking of the synthetic elements.
  • a procedure for incorporating the synthetic elements with this material is to achieve a dispersion of water and synthetic elements that is continuously stirred. Dispersing agents and/or penetrating agents and/or antifoaming agents are added to this dispersion in appropriate proportions, thus preventing the caking of the synthetic elements.
  • the dispersion is prepared in several loading and homogenising deposits prior to it being pumped to the paper production circuit in the machine.
  • FIG. 1 shows an enlarged section of paper incorporating this type of synthetic elements in its paste, such as that shown in the invention.
  • FIG. 2 equally represents an enlarged section of the paper incorporating the synthetic elements of the invention in strips.
  • FIG. 3 represents a schematic diagram of the tanks for preparing the aqueous solution of synthetic elements before being introduced in the paper manufacturing machine.
  • FIG. 1 shows an embodiment of a security paper or special paper ( 3 ) with the synthetic elements integrated in its paste, in this case in the shape of fibres ( 1 ) of the invention, in the same manner as in a traditional embodiment of the state-of-the-art, achieving that, despite these fibres being made in polypropylene, which does not present affinity towards water, such fibres are not caked or superficially retained on the paper itself, but randomly distributed inside the paper formed.
  • FIG. 2 is a variant of the embodiment of a security paper or special paper ( 3 ) wherein the synthetic elements of the invention, in this case again in the form of fibres ( 1 ), can be integrated in strips ( 4 ) by means of controlled insertion techniques for inserting such fibres inside the paper during their manufacture, controlling the depth at which said fibre strips are introduced, so that they remained superficially or embedded inside the paper thus formed.
  • FIG. 3 represents a schematic diagram for the procedure of preparing an aqueous solution of the synthetic elements, wherein these are initially conditioned inside an aqueous dispersion in a tank ( 5 ), wherein an amount of dispersing and/or penetrating and/or antifoaming agents is conditioned in an adequate amount, as well as the synthetic elements and the aqueous base for the suspension thereof, said suspension being stirred.
  • the dispersion thus prepared then goes through a homogenising step ( 6 ) and is then dosed by means of appropriate pumps ( 7 ) towards the entry in the paper manufacturing machine ( 8 ) for said synthetic elements to be integrated en masse or in a controlled manner.
  • POLISAL® is an aqueous solution of a yellowish sodium polyacrylate with an approximate density of 1.3 gr/cm3, which is a very active product for dispersion and refinement of the pigments used in the paper industry, especially for coating pigments.
  • the dispersing agent AMP-90® is an aqueous solution of 2-amino-2-methyl-1-propanol.
  • This disposing agent is colourless, with a relatively low viscosity and remains liquid at pretty low temperatures, such as ⁇ 37° C., which allows easy and adequate handling in industrial plants.
  • This product is a very efficient dispersing agent for pigments in plastic paints and, as a fatty acid salt, emulsifier in non-mixing water-liquid systems. It also provides pH stability, low odour and anticorrosive properties, and would even increase the acceptance of universal colorants.
  • This product's density is of 0.949 gr/cm3 at 25° C.
  • NOPCOWET LO® which is a synergic mixture of surface-active humectants and detergents such as Alkyl phosphate and potassium salt, which in the alkaline bleaching process facilitate the uniform impregnation of bleach in the entire paste to be treated, facilitating the elimination of waxy compounds coating the fibres. Due to its detergent effect it carries away the dirt on the fibres
  • AFRANIL MG® by BASF, which is a mixture of aliphatic hydroxide compounds in an aqueous emulsion. It has a density of approximately 0.960 gr/cm3 and a pH of approximately 9. This product has a good deaeration effect for the mixtures it is inserted into, with the advantage that water-repellent impurities do not accumulate, that is, it has a dispersing effect.
  • Security paper manufacturing tests have been performed, in which the synthetic elements of the invention have been inserted en masse in the form of fibres with a fluorescent feature, comparing it with the security paper with viscous or polyamide fibres as performed in the known state of the art.
  • These security papers have been subjected to several tests in order to verify the stability of the fluorescence characteristics of the fibres with spectacular results. These tests are basically of three types: the first are subjecting these security papers to acids, the second subjecting them to the action of detergents and the third subjecting them to extreme heat and light situations.
  • the differences may vary according to pigment colour or the type of response expected but always with an improvement upon the current state of the art.
