Definitions
- the invention relates to a sheet or film which can be used for manufacturing security documents, which is printable and which has a high print rendering, as well as good resistance to circulation, especially after printing.
- the invention relates more particularly to sheets of paper for banknotes or other valuable securities which can in particular be printed by offset printing and / or by printing.
- composition for surface treatment or impregnation of a sheet so as to simultaneously give it properties of good printability and resistance to circulation.
- security documents for example papers for banknotes or for checks or any other security of value include chemical or physical means of authentication and / or indicators of falsification.
- falsification indicator means react, for example, to acids (hydrochloric, citric, acetic, sulfuric, etc.), to bases (especially soda), to oxidants (bleach), to reducers and to solvents.
- a given security document does not generally contain all of these means, since the cost of manufacturing the document increases with the number of authentication means and with their sophistication.
- the security documents always include a superficial impression and this is why it is necessary to carry out a printing of superior quality, both with regard to the colors and the layout, so as to make it difficult for them to be imitated by counterfeiters.
- the general public is not not very attentive to the quality of the drawings and / or prints brought to the surface of a security document, but knowledgeable people such as bank staff or merchants are very sensitive to the details of a drawing, the finesse and in general when printed, and can therefore judge the authenticity of a document, with the naked eye or with a magnifying glass.
- the print rendering is the fact that the line obtained by printing is perfectly clear, that is to say that it does not have any burrs or in term used by the skilled person in the "feathering". These burrs cause the lines to spread more than is desired, hence the difficulty of producing an impression comprising very close lines without the risk of blurring. Therefore, the central bank that prints the paper to obtain security documents is forced to make insufficiently fine prints. It is therefore difficult to produce micro-prints. However, micro-prints are very useful as security elements because they are difficult to reproduce by photocopiers who currently cannot reproduce very fine prints. Print rendering is also characterized by the color density of the print.
- the human eye has sufficient resolution to distinguish between an impression having a good rendering and an impression comprising a "feathering".
- the printing rendering on the security documents is quite poor and it is therefore possible to easily forge them using color photocopiers which are capable of reproducing almost exactly the color tones of an authentic document. Counterfeiting will not be obvious to the eye, even to a knowledgeable person, since the print rendering of the authentic document is not sufficiently superior to that of the image reproduced by photocopying.
- the quality and beauty of the print also contributes to the brand image of the document sender.
- the quality of the printing contributes to the prestige of the country which puts them into circulation. This is another reason to be careful when printing these documents.
- pigments and binders that can be used to make such a layer is very wide. Pigments are most often mineral fillers, sometimes plastic pigments.
- the binders can be chosen from starch, casein, animal glue, polyvinyl alcohol, natural or synthetic latex, etc.
- pigmented layers containing bentonites have been studied in the field of usual printing-writing papers (TAPPI, vol.59, n ° 12, December 1976, NEW YORK, pages 76-80; R.L. JANES et Al).
- the sheet of paper is impregnated, before printing, in a bath which essentially contains one or more binders chosen for their very high mechanical characteristics.
- the present invention therefore aims to improve the rendering printing of a sheet intended for the production of security documents, without degrading the resistance to circulation of the printed documents.
- the invention also aims to improve the resistance to circulation of such documents.
- the invention therefore aims to provide a sheet intended for the production of security documents which simultaneously has the following properties:
- the Applicant has overcome the prejudices of those skilled in the art, namely that it has subjected the sheet to a surface treatment, by means of a particular composition, this treatment possibly being, for example, a coating.
- the Applicant after having tried numerous compositions containing at least one binder and at least one filler has managed, surprisingly, to solve the problems posed by using a composition containing at least one filler and at least one binder of elastomeric character.
- composition containing a binder and a filler does not increase the receptivity of the sheet to soiling since it improves the receptivity of the sheet to inks.
- the invention provides a printable sheet, usable for manufacturing security documents, having a high print rendering and resistance to circulation, which is characterized by the fact that at least one of its faces is treated by a composition comprising at least one filler and at least one elastomeric binder.
- the elastomeric binder can however be used in admixture with other binders usually used in stationery. Tests carried out by the Applicant have shown that binders such as starch or PVA, even insolubilized, do not allow the impression required for security documents to be maintained when these binders are used alone with a filler.
- the elastomeric binder can be chosen from the group formed by aqueous dispersions of polyurethane, acrylate copolymers, optionally carboxylated styrene-butadiene copolymer, polymers one of the monomers of which is acrylonitrile or isoprene or neoprene , or their mixtures.
- a polyurethane is preferably used.
- the charge can have any BET specific surface. It may as well have a specific surface area measured according to the BET method (standard DIN 66131) which is small, of the order of 5 to 20 ⁇ rVg . that a specific surface which is high, for example of the order of 200 to 300 m 2 / g (the BET method gives a measurement of the total specific surface).
- coats of the "reverse-roll”, “champion”, “bill-blade”, dragging blade or air knife type can be used. It is preferable to choose an air knife coater. Indeed, this type of coating respects the filigree, that is to say its relief.
- the sheet to be treated according to the invention can be a sheet based on a cellulosic composition, partially or completely synthetic or a film of synthetic material.
- the sheet is bank note paper.
- the invention also aims to provide a composition for the treatment of at least one face of a sheet, giving this sheet a high print rendering and resistance to circulation, which is characterized by the fact that it comprises at least one filler and at least one binder of an elastomeric nature.
- the composition intended for treating the surface of the sheet according to the invention comprises: - 1 to 50 parts by dry weight of a filler, in particular mineral
- composition being produced in an aqueous medium and making a total of 100 parts by weight.
- a sheet is formed on a paper machine (with a flat table or with a round shape) optionally comprising a watermarking device, from a composition of cellulose fibers, for example cotton. This sheet is then coated on an air knife coater with an aqueous composition containing:
- composition being produced in an aqueous medium and making a total of 100 parts by weight.
- the weight of the deposited layer is between 1 and 15 g / m 2 in dry, preferably around 10 g / m 2 in dry.
- the sheets manufactured according to the invention can be printed in intaglio and offset, their resistance to circulation is tested according to the following four criteria:
- a control sheet which has not been treated is compared with a sheet treated with the pigmented compositions according to the invention. It is observed that the print rendering is much better for the sheets produced according to the invention and that the resistance of the sheet to circulation, in particular after printing, is not less than that of the control. In some cases it has even been improved.
- Figure 1 is a photograph enlarged 7 times of a print of the first three letters of ARJOMARI, this print being made on a paper for traditional bank note.
- FIG. 2 is a photograph of the impression made on a paper according to the invention.
- Figure 3 is a 20-fold enlarged photograph of the letter A from the print of Figure 1.
- Figure 4 is a 20-fold enlarged photograph of the letter R from the print of Figure 2.
- Each ticket is crumpled in an IGT crumpling device. Then we iron it manually. It is placed in a bottle which hermetically closes in the presence of beads of 20 mm in diameter and of 10-cent pieces which have been previously soiled with a powder containing yellow, brown dyes, carbon black and vermicullite. The bottle is placed in a TURBULA device which is rotated for 15 min.
- the ticket is subjected to a prior crumpling. Then place it in a bottle, as above, but add powder containing the dyes and an artificial sweat composition.
- the banknotes tested are compared with each other or with a control banknote tested under the same conditions.
- the degree of soiling is assessed visually or a measurement of the whiteness is carried out.
- a sheet is made on a paper machine from an aqueous suspension of cellulose fibers, optionally in admixture with mineral or synthetic fibers and other additives used in stationery.
- This sheet is coated using a MEYER bar, # 0.4 with an aqueous composition comprising, in dryness relative to the total composition:
- a rheology modifier for example carboxymethylcellulose or a dispersion of acrylate / (eth) acrylic acid.
- the final viscosity is 50 Pa.s, at room temperature, measured with a BROOKFIELD viscometer, mobile no.1, at 100 revolutions / min.
- the dry layer weight is 11 g / m 2 .
- This sheet is intaglio printed and subjected to the circulation resistance tests mentioned above.
- This sheet is compared to a control sheet produced under the same conditions but not coated.
- EXAMPLE 1 A sheet is made on a paper machine from an aqueous suspension of cellulose fibers, optionally in admixture with mineral or synthetic fibers and other additives used in stationery.
- This sheet is coated using a MEYER bar, # 0.4 with an aqueous composition comprising, in dryness relative to the total composition: - an elastomeric binder, aqueous dispersion of polyurethane
- the final viscosity is 50 mPa.s, at room temperature, measured with a BR00KFIELD viscometer, mobile n ⁇ l, at 100 revolutions / min.
- the dry layer weight is 11 g / m 2 .
- This sheet is intaglio printed and subjected to the circulation resistance tests mentioned above.
- This sheet is compared to the control sheet used in the preceding comparative example.
- a sheet is produced on a paper machine from the fiber composition of Example 1. This sheet is coated using a MEYER bar, n ° 0.4 with an aqueous composition comprising, in dry compared to the total composition:
- the final viscosity is 50 mPa.s, at room temperature, measured with a BR00KFIELD viscometer, mobile no.1, at 100 revolutions / min.
- the dry layer weight is 5 g / m 2 .
- Example 1 The sheet is printed and tests are carried out as in Example 1. This sheet is compared ( Figures 2 and 4) to a control sheet ( Figures 1 and 3). The print rendering is significantly improved and the resistance of the sheet to circulation is not degraded, it has even been improved.
