Definitions

  • the present invention relates to a method for manufacturing a tamper-proof identification card comprising photographs as well as a card obtained by this method.
  • a transparent plastic film is superficially bonded so as to protect the assembly against damage.
  • Such a card has the drawback of not being completely inviolable because the protective film can be relatively easily peeled off and the photograph retouched, so that fraud is relatively easy.
  • it has been proposed to carry out photography by depositing a photosensitive layer directly on the support in the manner described in French patent 2 129 198.
  • the polyvinyl chloride support or the like is coated with a photosensitive layer composed of a product sold under the trade name DYLUX.
  • the photosensitive material can be diffused in the mass of the support itself or in the binder layer deposited on the support.
  • the alphanumeric inscriptions and the photography are carried out when the card already has the finished appearance, that is to say coated with its transparent protective film.
  • the drawback of cards produced according to this method is mainly due to the fact that the above-mentioned photosensitive emulsion is not temperature stable. During the complexing operation, which generally takes place hot, the photosensitive layer is liable to degrade.
  • the stabilization of the background of the photography is imperfect using a simple exposure to light. Because the photosensitive layer is protected by a transparent film, it is then no longer possible to stabilize the image after development by washing.
  • FR-A-2,059,125, FR-A-2,059,126 and US-A-4,108,664 teach that a composition comprising a diazonium salt must, in order to adhere to a support of plastic material such as PVC, a coupler and stabilizing aids such as polyvinyl acetate.
  • the invention is characterized in that the solvent is a solvent for the support.
  • the solvent is a solvent for the support.
  • the protective film it is not necessary in the method according to the invention to immediately paste onto the developed photograph, the protective film to make the identification card inviolable.
  • This laminating operation can be carried out several hours or days after the development of the images, without any time limitation. It has been found that in order to achieve total inviolability of the identification cards carrying a sensitive diazo layer, it was surprisingly necessary to produce a photosensitive layer comprising an intimate mixture of the photosensitive products and of the heat-bonding resin. This intimate mixing must be carried out before coating the photosensitive layer on the support (or the protective film) to achieve the desired result.
  • a solvent which is a solvent for the support so as to slightly penetrate said layer into said support.
  • the first and second resins will have a VICAT softening point of between 40 ° C and 140 ° C and preferably between 50 ° C and 100 ° C.
  • These resins will preferably be chosen from polyvinyl acetate, polyvinyl aceto-chloride, polyvinyl chloride and polyesters.
  • the choice of the first resin which is intimately mixed in a solvent with the photosensitive compounds (diazonium salt, coupler, adjuvants) will obviously be made according to its compatibility with these various elements of the photosensitive layer.
  • compatibility is meant the non-precipitation of the resin solution when the elements of the photosensitive composition are introduced, or vice versa.
  • simple manipulations those skilled in the art will note the existence or not of a precipitation of the photosensitive solution.
  • any diazonium salt soluble in organic solvents can be chosen.
  • the proportions between the diazonium salt and the coupler will vary, by weight, between 0.1 and 10 and preferably between 0.3 and 3.
  • the quantity of diazonium salt and of coupler present on the support in the photosensitive zones will vary between 5% and 50% by weight, while the quantity of first resin (alone or mixture of resins) will vary between 50% and 95% by weight (from these proportions, all adjuvants are excluded).
  • the choice of the solvent among the solvents of the support makes it possible to obtain an exceptional adhesion of the layer as well as the reproduction of the half-tones.
  • the Applicant has found that the photosensitive solution must have a viscosity of between 600 cps and 4.000 cps at 20 ° C.
  • the viscosity of the photosensitive layer is less than 600 cps, the solution is too fluid and flows alone through the mesh of the screen, without using the squeegee used for this purpose: the resulting work is then too imprecise for making identification cards.
  • wefts of nylon or polyester threads comprising from 70 to 165 threads / cm.
  • the supports used in the context of the present invention will preferably be made of polyvinyl chloride or vinyl acetochloride, optionally comprising fillers and / or dyes.
  • the images are then developed in ammonia vapors.
  • the card is then ready to be laminated with a protective film under pressure and in the presence of heat, in a manner known per se.
  • protective film use will preferably be made of a polyvinyl chloride, vinyl acetochloride, polyester or polystyrene film.
  • the protective film is made of a material identical to that which can constitute the first or the second resin, it is possible in this case to avoid coating this second resin on the said film since the latter is then directly fusible.
  • all the steps of the method according to the invention make it possible to deposit magnetic tracks, for example on the back of the card support without any deterioration of these during the manufacture of said card.
  • embossings representing numbers, letters, etc. can be produced on said card, in a manner known per se.
  • stamps are deposited by screen printing, as described above.
  • this technique one can refer to the work entitled "The Techniques of the Serigraphy" - Michel CAZA - Presses of the Present Time.
  • Fig. 2 is a sectional view of an identification card as shown in FIG 1. This section is made before plasticizing the card.
  • the support 20 is coated with photosensitive zones 21 and 22 deposited by screen printing. A photographic positive is then deposited on each sensitive part of the card and cold exposure of the entire support is carried out with ultraviolet radiation using a "NU-ARC" type chassis.
  • the colored parts are then developed by passing through an ammonia atmosphere.
  • the card is then coated on both sides with a transparent protective film, as shown in fig. 3 by references 23 and 24. Then hot pressing is carried out under the usual conditions well known to those skilled in the art in this type of application.
  • the core 30 of the card coated with the protective film 34 is then associated with the protective film 33 as in FIG. 3, by hot pressing.
  • the viscosity of the solution obtained is 1,250 cps.
  • This solution is coated on a polyvinyl chloride support having magnetic tracks on the back using a "silk screen" in monofilament polyester yarn of weft 100 from Etablatoriums BUISINE having a mesh opening of 58 microns, a wire diameter of 40 microns and a thickness of 65 microns.
  • the thickness of the deposited layer, after evaporation of the solvent is 5 microns.
  • the image is then developed by passing through ammonia vapors and a positive blue-black image is obtained which adheres perfectly to the support.
  • Said card (or set of cards, as described in FIG. 1) is then coated with a sheet of transparent vinyl acetochloride and complexing is carried out at 110 ° C. under pressure.
  • the solution obtained has a viscosity of 600 cps.
  • Example 1 This solution is coated on a polyvinyl chloride support as in Example 1. After exposure and development, a brown-sepia image is obtained. Complexing is then carried out at 110 ° C. under pressure with a transparent polyvinyl chloride protective film coated with a layer 3 microns thick of polyvinyl acetate. The same inviolability results are obtained for the card as in Example 1.
  • a photosensitive solution with a viscosity of 2,500 cps is obtained.
  • This solution is deposited on a vinyl acetochloride support using a 70 frame (opening: 90 microns - film size: 55 microns - frame thickness: 90 microns).
  • the thickness of the deposited layer is 6 microns.
  • the viscosity of the solution obtained is 600 cps.
  • a card is produced with this solution as described in Example 1 under the same conditions (blue-black color image).
  • This solution has a viscosity of 1,600 cps.
  • a layer 3 microns thick is coated with said solution using a 140 weft (mesh opening: 33 microns - wire diameter: 37 microns - weft thickness: 66 microns) on a transparent film of protection of vinyl acetochloride. After exposure and development as in Example 1, a brown-black image is obtained. The film (with the developed images) is then complexed at 110 ° C and under pressure with a polyvinyl chloride support. The same results are obtained as in Example 1.
