Definitions

  • the invention relates to a method for producing a protective product with a transferable protective film, which can be used to cover and protect a document or other element on the surface. It extends to the protection product obtained.
  • cellulosic or nitrocellulosic transfer films are known (see for example patent FR 2 427 208) or films obtained by alkyd-urethane deposition (see for example patent US 4 308 310), which are used to fill a surface with a pattern.
  • these marking films cannot be used to meet the protection objectives targeted by the invention, because they are very fragile and do not resist light solvents and, a fortiori, more powerful solvents such as cellulose diluents; in particular, these films can be easily removed without alter the support and therefore cannot constitute protection against falsification.
  • the present invention proposes to provide a new protection product which can be used cold by simple pressure, in the manner of a transfer film by any person without any particular material.
  • the essential objective of the invention is to provide a product which gives very safe protection both with regard to external stressors and against forgery; in particular, the invention aims to provide a product having a transferable protective film which is resistant to light solvents as well as to cellulosic solvents and whose elimination or attempted elimination is necessarily accompanied by destruction or very apparent alteration of the document, for most of the constituent materials and in particular for paper documents.
  • Another objective is to make it possible to personalize the document, by adding to it patterns or a screen, either directly visible, or invisible in sunlight but detectable under ultraviolet radiation.
  • Another objective is to avoid significantly modifying the physical characteristics of the protected document and in particular to preserve it with flexibility and folding possibilities similar to those which it initially possessed.
  • Another objective of the invention is to indicate a process for producing the targeted protection product benefiting from a low cost price, this cost, combined with the ease of implementation of the product, making it possible to generalize the use of the produced to the most common documents.
  • Another objective is to indicate a process suitable for obtaining transferable protective films, of various shapes depending on the envisaged end use.
  • the process targeted by the invention for producing a protective product with a protective film transferable cold by simple pressure, uses as a base a layer obtained by printing using a two-component polymerizable liquid mixture containing a polyol. hydroxylated and an isocyanate or polyisocyanate, mixture capable of polymerizing in situ to result in a thin transparent layer of polyurethane.
  • the process according to the invention for the manufacture of the protective product consists in producing a single impression on a non-stick support sheet by means of a polymerizable liquid mixture as shown below. above defined so as to obtain, after in situ polymerization, a thin transparent film of polyurethane on said support sheet, and to cover said film with a transparent adhesive layer.
  • the method according to the invention consists: . to carry out a first continuous impression on a non-stick support sheet by means of a polymerizable liquid mixture as defined above, so as to generate the in situ polymerization of the mixture leading to a first transparent layer of polyurethane, .
  • the method of the invention leads to coating by printing the support sheet with a thin polyurethane film, monolayer in the first case, multilayer in the second.
  • Each printing can be carried out by any printing process known per se and in particular by screen printing or rotogravure.
  • the liquid mixture used for printing is prepared beforehand in particular in a proportion of 1.8 to 2.2 doses of hydroxylated polyol for a dose of isocyanate or polyisocyanate.
  • the adhesive layer covering this film can in turn be produced, before complete polymerization of the last layer of the film, by printing the latter by means of transparent adhesive material, in particular by serigraphy or rotogravure.
  • the adhesive material used is for example of the acrylic type known per se.
  • a silicone protective sheet (or similarly treated) is then placed over the adhesive layer to protect it until use.
  • a protective product is thus obtained which is in sheet form, which can be distributed to the end user and whose implementation by the latter is extremely simple and requires no equipment.
  • To protect a document or any similar surface just remove the silicone sheet, apply the cold product to the surface to be protected so that the adhesive layer covers this surface, exert pressure on the surface of the support sheet in order to generate the transfer, and detach said support sheet.
  • Such a process, carried out cold without any particular precautions, can be carried out by any person without any particular skill.
  • the intermediate layer located in an inaccessible position between the other two allows the documents to be protected to be tamper-proof.
  • the colored substance placed in the polymerizable mixture of this intermediate layer will depend on the applications: invisible substance reacting to ultraviolet (or possibly infrared), visible substance undergoing a color change under radiation (ultraviolet %), opaque substance forming a pattern or an opaque frame on the document or parts of it.
  • the protective film according to the invention can be easily adapted to cover and protect one or more surfaces of determined shapes; it suffices that the impression (s) by means of the polymerizable liquid mixture (s), then the impression by means of the adhesive material are carried out on one or portions of the support sheet of shapes corresponding to those of the surfaces to be protected. It should be noted that the process of the invention makes it possible to produce protective products suitable for covering large areas, and this, at a reduced cost taking into account the extreme thinness of the polyurethane film and therefore the low quantities of materials. first used.
  • the method illustrated by way of example is implemented on screen printing machines, in particular on traditional snap-on machines (hinged screen) or on machines with a full lift screen (screen movable in translation).
  • the two types of machine can be used interchangeably.
  • the monolayer film product referred to in Figures (1a-1c) comprises a transparent support sheet 1 ( Figure 1a) of the so-called non-adherent type, that is to say capable of developing only weak bonding forces with most polymers.
  • this support sheet can be a polystyrene sheet with a grammage of the order of 120 g / m2.
  • This support sheet 1 is chosen to be larger than that of the surface to be protected.
  • This mixture can in particular be prepared by adding two doses of hydroxylated polyacrylic resin or hydroxylated polyester resin, or of low molecular weight hydroxylated polyether resin, and a dose of aliphatic or aromatic trifunctional polyisocyanate (for example, polyacrylic resin "ref. U8560” and trimerized hexamethylene diisocyanate “ref. U8580", sold by the "CHIMITEC Laboratory”).
  • hydroxylated polyacrylic resin or hydroxylated polyester resin or of low molecular weight hydroxylated polyether resin
  • aliphatic or aromatic trifunctional polyisocyanate for example, polyacrylic resin "ref. U8560” and trimerized hexamethylene diisocyanate "ref. U8580", sold by the "CHIMITEC Laboratory”
  • the quantity of mixture spread on the screen printing screen is adjusted to correspond to a thickness of 8 to 10 microns.
  • the mixture After printing on the support sheet 1, the mixture polymerizes and gives a thin transparent polyurethane film 2.
  • the printing is carried out in a shape corresponding to that of the surface to be protected, for example rectangular in the case shown diagrammatically in FIGS. 2a, 2b, 2c for the protection of identity cards.
  • the screen printing machine is cleaned every hour to prevent screen clogging.
  • the support sheet 1 and its polyurethane print 2 are then left in the open air in order to allow the polymerization to start.
  • the total duration of this is several days (of the order of 8 to 10 days).
  • the assembly is replaced on the screen printing machine to make a new impression above the film 2 by means of a transparent adhesive material.
  • the film will be allowed to polymerize between 3 and 36 hours and preferably approximately 4 or 5 hours. These periods make it possible to guarantee that the film is sufficiently dry and consistent to undergo a printing but with a polymerization still incomplete to allow better adhesion of the new printing.
  • This will be for example performed using an acrylic adhesive material of the type sold by "TIFLEX" under the reference "acrylic adhesive”.
  • This printing is carried out on the entire surface of the film 2 in order to coat it with a transparent adhesive layer 3 (FIG. 1b) whose thickness is similar to that of the film (between 5 and 50 microns and, in the example of 8 to 10 microns).
  • a silicone protective sheet 4 (FIG. 1c), the grammage of which can be of the order of 145 gr / m2.
  • the protection product thus obtained can be stored and distributed without special precautions.
  • FIGS. 2a, 2b and 2c an application of the invention has been shown diagrammatically for the protection of identity cards. This protection may be carried out by the administration responsible for establishing these cards, after the holder has affixed his signature and, where appropriate, fingerprints, at the same time as the identity card is given to him.
  • the protection product is shown diagrammatically in perspective in FIG. 2a, the silicone protective sheet 4 being removed.
  • the product After removing this protective sheet, the product is applied to the identity card (FIG. 2b), the impressions 2 and 3 of polyurethane and adhesive material having the shape of a rectangle of size corresponding to that of this card. These prints are matched to the surface of the card and the operator applies pressure which causes the adhesive layer 3 to adhere to the card with simultaneous transfer of the film 2.
  • the protective film is not very visible and does not significantly modify the flexibility of the card.
  • FIGS. 3a-3e illustrate (on a larger scale) the manufacture of a protection product with a multilayer polyurethane film.
  • the first step (FIGS. 3a) is similar to the first step of the process already described and consists in printing on a polystyrene support sheet 5 a transparent layer of polyurethane 6 by means of a polymerizable mixture identical to that already described.
  • a discontinuous intermediate printing 7 of drawings, patterns or screens is carried out on the first printing (FIG. 3b ).
  • a delay of the order of 4 to 5 hours gives good results (initial printing sufficiently consistent to allow intermediate printing, while allowing close adhesion of the layers due to the simultaneous polymerization phenomena at their interface).
  • This intermediate printing 7 is carried out with a similar base resin to which has been added a colored substance between 2 and 50% by weight, the polyisocyanate then being mixed.
  • a colored substance between 2 and 50% by weight
  • one of the following substances can be added in the form of a fine powder: - substance based on rare earths and metals, sold by "CHIMITEC” under the reference “Lumiton fluo UV codes” (between 2 and 25% by weight), in order to provide patterns invisible to sunlight, becoming fluorescent under ultraviolet radiation , - substance based on fluorescent organic dyes having a long series of double bonds in cyclic or benzene form, sold by "CHIMITEC” under the reference “Lumiton fluo LJ” (between 25% and 50% by weight), in order to provide patterns fluorescent in sunlight, having intense fluorescence under ultraviolet radiation with color change, - opaque pigments based on titanium oxide or carbon black (from 5% to 25% by weight), - transparent organic pigments based on ophthalocyanine (blue) or yellow “HANSA” (between
  • a second printing 8 is carried out identical to printing 6 in order to obtain a new transparent layer of polyurethane (FIG. 3c).
  • This printing is carried out in the same time as previously (between 3 and 36 hours and preferably 4 to 5 hours after the interlayer printing).
  • a polyurethane composite film is obtained with an integrated pattern or weft, the layers no longer being separable.
  • This multilayer film may in particular have a thickness of the order of 8 to 20 microns.
  • Printing of transparent adhesive material 9 is then carried out as previously (FIG. 3d). This impression is preferably made having complete polymerization of the layer 8 within a period of between 3 and 36 hours and preferably of the order of 4 to 5 hours.
  • the assembly is then covered by a silicone protective sheet 10 similar to that of the product previously described.
  • the protection product thus obtained can be stored and distributed without special precautions. Its use is similar to that already described for the product with a single-layer polyurethane film. It should be noted that, if necessary, several intermediate prints can be superimposed by successive passes on the machine (with a delay between passes of between 3 and 36 hours and preferably of the order of 4 to 5 hours).
