Definitions
- the present invention relates to a high resolution coating process. It also relates to products which are transparent to visible light. allowing to filter a certain range of electromagnetic wavelengths.
- a coating according to these methods is generally total, sometimes partial, but none of these coatings makes it possible to produce patterns presenting high resolution.
- US Patent 5,721,007 describes a process in which a support is coated a metal layer; an electrically insulating varnish is printed on high resolution on a first part of the coated support; one or more metallic layers are deposited on a second part of the support, i.e. the part of the support not covered by the varnish, by electrolysis so as to form the conductive circuits of the circuit; the electrically insulating mask is removed in order to be able to engrave the coating of the support not covered by the layer or the metallic layers deposited on the support between the varnish.
- This method is eg used for the manufacture of electric circuits, in particular for the manufacture of flat cables. Although this method allows printing to high resolution, it does not allow a metallic deposit on the varnish.
- the object of the present invention is therefore to propose a manufacturing process a multilayer substrate having high resolution patterns and allowing a metallic deposit on the varnish.
- the varnish is a loaded varnish.
- the loaded varnish not only protects in specific places the support but also to carry out a metallic deposit later on the varnish charge.
- Printing a high-resolution varnish on a support creates fine and high resolution patterns on this support.
- This process is independent of the support and the method of coating the support. In principle, this process is applicable to any medium
- the support Before printing, the support can be coated with a layer which includes preferably metal.
- the loaded varnish may for example include conductive materials and / or barrier materials to respectively filter the waves electromagnetic.
- the material forming a barrier to respectively filtering electromagnetic waves preferably absorbs and / or reflects at least part of the electromagnetic waves.
- the treatment of the coated support by electrolysis advantageously comprises electrolytic etching of the coating on the unprinted part of the support coating.
- the support is subjected to a deposit electrolytic on the conductive printed part after washing and drying.
- Support treatment by electrolysis includes electrolytic deposition one or more metals or their alloys on the printed part of the support.
- the printing of the varnish on the support is preferably carried out by gravure printing.
- Photogravure is advantageously carried out by a photogravure group comprising at least one cylinder whose printing areas are made of engraved cells, the outermost of each drawing are interconnected to ensure linear continuity of the contours.
- the cylinder cells are preferably arranged in a line size of 175 700 cells per inch (per 2.5 cm), preferably 350 cells per inch (by 2.5 cm).
- the contours of the contours are preferably connected between them to achieve continuity of graphics and avoid any tooth effect.
- the photogravure group is able to print a coating with drawings very fine, between 150 and 25 ⁇ m, preferably 50 ⁇ m.
- the etching is preferably carried out by electrolysis between the coating metal of the support to be treated and an anode bathed in an electrolyte aqueous.
- the anode is preferably a titanium anode made up of a folded sheet.
- the aqueous electrolyte advantageously comprises a mineral acid and its salt or a mineral base and its salt, preferably NaOH + concentrated NaCI at 10%.
- the electrolyte is chosen in such a way that the products released in aqueous phase by electrolysis attack metallic coating with a mixture of the acid type and its salts or with an alkaline and its salts halogens.
- the reflection and transmission rates can vary from 0 to 100% while the absorption rate can vary from 0 to 50%.
- the electrolytic deposition is preferably carried out by electrolysis of one or several metals and / or their alloy, by dissolving a soluble electrode containing at least the metal or metals of the electrode.
- the metallic deposit or successive metallic deposits allow to create drawings with high resolution and high precision on a support.
- the products resulting from the process described above may have characteristics useful, especially for uses in the wave field electromagnetic, especially in the microwave field.
- the process makes it possible to obtain multilayer products having characteristics of reflection, transmission and absorption of electromagnetic radiation very specific incidents.
- radiation electromagnetic incident on the product can be transmitted at a rate of 0 to 100%, reflected at a rate of 0 to 100% and / or absorbed at a rate of 0 to 50%.
- the use of such products is very diverse; they can for example be used as a filter for electromagnetic radiation, these filters being transparent in visible light.
- a heat-resistant polymer film can be coated with preferably polyester, a layer that heats up when electromagnetic energy incident is partially absorbed by the coating. This coating can be metallic with a resistivity between 0.0005 and 0.1 ohm / square, preferably 0.01 ohm / square, e.g.
- the product is, under these conditions, of a very high visual transparency and heats up at high temperatures (from 200 to 300 ° C) when struck by electromagnetic radiation and in particular microwaves. Heat energy can represent up to 50% of the incident energy.
- the amount of energy absorbed, transmitted or reflected varies according to the importance and the distribution of the coating applied to the film. Below a threshold predetermined, the transmitted energy is greater than the reflected energy, beyond of this threshold, the transmitted energy is lower than the reflected energy.
- the method also makes it possible to create multilayer products.
- On a first metallic deposit you can deposit a second metallic deposit by ironing the support through the printing station and the processing station.
- filtering means in the context of this that between 0 and 99.9% and preferably between 0 and 95% of the incident waves pass through the product.
- the product can therefore ultimately be transparent or opaque to a determined electromagnetic wavelength range.
- transparent to visible light means in the context of the shows that between 80 and 99.9% and preferably between 90 and 95% of the visible light pass through the product.
- the product comprises a layer additional metallic coating covering at least part of the layer of varnish.
- An additional layer of varnish can at least partially cover the metallic coating which can in turn be covered, at least in part by an additional layer of plaster.
- the basic support is generally a film of synthetic material such as eg polyester film.
- any other material may also be suitable as long as it is transparent to visible light and to the range electromagnetic waves chosen.
- it must be possible to cover with a high resolution pattern including a coating and / or varnish.
- the product as proposed generally absorbs between 0 and 95% of the determined range of incident electromagnetic waves, reflects between 0 and 100% and / or transmits between 0 and 100% of the waves not absorbed depending on the pattern, nature and amount of coating.
- the product absorbs from 0 to 50% of energy from electromagnetic waves and reflects and / or transmits energy not absorbed.
- the product therefore constitutes a filter to a range of electromagnetic waves and transparent to visible light, it can even constitute an opaque filter to electromagnetic waves and transparent to visible light.
- the electromagnetic waves are eg microwaves and the product can therefore be used as packaging for products microwaveable, i.e. for food packaging that can be reheated in a microwave oven.
- Fig. 1A shows a section through a support film 10, on which - at fig. 1B - a discontinuous layer 20 of charged varnish is printed.
- fig. 1C we see a metal layer 30 deposited by electrolysis on the layer 20 printed film 10. It is therefore possible to deposit a metal layer 30 having high resolution drawing on a blank film, that is to say on a film without continuous metallic coating. In this way, you can get movies with high resolution metallic drawings on film 10.
- Fig. 2A shows a film 10 comprising a metal coating 15.

- Fig. 5 shows a heat-resistant polymer film, preferably polyester, coated with a layer that heats up when electromagnetic energy incident is partially absorbed by the coating which can be metallic with a conductivity between 1 and 2,000 ohm / square, preferably 100 ohm / square, for example consisting of a layer of aluminum obtained by sublimation under vacuum, with a thickness of 10 to 10,000 Angstroms, preferably with an optical density of 0.6.
- the packaging material is very high visual transparency and heats up to 280 ° C when electromagnetic radiation with a frequency of 2,450 MHz strikes him; the heat energy obtained can represent up to 50% of the incident energy.
- the transmitted energy is greater than the reflected energy. Beyond the same threshold, it is the reflected energy which prevails over that transmitted.
- FIG. 6 Another example of application is shown in FIG. 6 in which a film is applied against a microwave oven door.
- a protective varnish comprising products which reinforce the absorbing and / or reflecting effect of a film
- This material consists of an aluminum coating obtained by sublimation under vacuum, of a thickness at least equal to 600 Angström covered with a varnish charged with particles which allow to reach an overall conductivity between 1 and 10 ohm / square preferably 2.5 ohm / square.
- These particles are preferably aluminum elements of small dimensions (5 to 15 ⁇ m, preferably 10 ⁇ m) obtained by vacuum deposition.
- the wavelength of common household microwave ovens is 12.5 cm.
- the method according to the present invention makes it possible to produce lines of 50 ⁇ m.
- a grid is obtained (FIG. 10) which is opaque in the microwave.
- a film is therefore obtained which is almost entirely transparent to visible light, but which is nonetheless opaque for microwaves. This film can be applied against a microwave oven door.
- the door window is transparent to visible light, so you can clearly see what's going on inside the oven, however microwaves are not transmitted through the door.
- Fig. 7 shows a cap for a “Liège coffee” type drink which can be placed on a container containing coffee in its lower part and in the upper part of the cream floating on the coffee, before heating it in a microwave oven.
- the cap On the container is placed the cap which, in its upper part, surrounding the cream, reflects the microwave rays and which, in its lower part, surrounding the coffee, absorbs part of the microwave rays. Through therefore, the cream remains cold while the heat generated by the absorption microwave rays in the lower part is transmitted to the coffee for heat it. With such a headdress, one obtains a Liège coffee with coffee hot and warm creamy cream.
- FIG. 8 Another example of the use of a material according to the present invention is a PR meal tray for food to be carried at various temperatures (Fig. 8).
- the starter (a) should be eaten warm, the main dish (b) hot and cold ice (c). These 3 types of food will be placed on a tray thermo-formed PR meal and closed by a cover (not shown) constituting enclosures communicating to the outside only through vents (not shown).
- a cover constituting enclosures communicating to the outside only through vents (not shown).
- the enclosure (a) with a metallic coating of conductivity 0.1 Mohm / square around the fish the enclosure (b) will have no coating, the enclosure (c) will coated with a multilayer film, will be equivalent to that allowing to make microwave radiation barrier (Fig. 6) so that ice does not is not heated.

- the BA4 strip passes in a drying station E and. finally, at an F checkpoint to arrive on the rewinder G.
- the feed station A includes an unwinder A1 which carries the spool A2. This unwinder is driven by a motor controlled by an A3 call group, which regulates a controlled voltage in the BA1 band.
- the tape then passes in the printing station B which includes a printing unit (fig. 10 and 11) with an inkwell B1, a gravure cylinder B2 plunging into the inkwell B1 for cover the surface with rotogravure cells and the window contour.
- This cylinder cooperates with a doctor blade B3 which removes the ink on the surface so as not to leave only the ink inside the cells or the engraving.

- the liquid level in the inkwell B1 is adjusted by an overflow B7 with return to reservoir 84, so that the gravure cylinder B2 is always immersed at the same depth in the inkwell B1.
- the cylinder B2 cooperates with a pressure cylinder B10 placed above the strip BA1, the cylinder B2 being below the strip

- the cells are represented by black squares with rounded corners possibly truncated, separated by low walls (partitions or also called bridges) K101, white.
- All the cells or basins are surrounded here by a net, that is to say a very narrow notch which fills with ink but limits spreading the ink in the cells to give the printed image a continuous, precise outline limiting the window limit precisely and predetermined
- this thread K102 passes contiguously over the bowls or adjacent to them.
- the window 1200 also includes cells K200 separated by low walls K201 and the whole is surrounded by a thread K202 which is further from the edge of the cells K200 (truncated or not) that in the embodiment of FIG. 12B.
- the fineness of the line constituting the net depends on the resolution of the tracer which designed the window (s); thus, with the choice between the forms of engraving of figs. 12B and 12C depends on the viscosity of the liquid used for this printing. As indicated, this liquid is, once dried, a passivation product, i.e. inert vis-à-vis the physicochemical action to be performed.
- fig. 12D shows the 1300 printed image with its very precise outline and not serrated.

- This washing station D is consists of different return cylinders D1, D2 leading the strip BA3 in a first tank D4 then in a second tank D5. These tanks contain an electrolyte flushing liquid and / or a solvent and coating. The detailed structure of these washing tanks will not be given. It is a set of cylinders defining a strip circulation path in the washing bath.
- Washing is carried out with spins between steel cylinders and polymer cylinders to limit entrainment and facilitate drying by evaporation of the washing liquid, so that the film is dry and streak-free electrolyte incompatible with its subsequent use.
- the strip BA4 Downstream of washing station D, the strip BA4 passes into the drying station E equipped with ventilation and air extraction means E1, E2, E3, E4 and, finally, the dried BAS strip passes through a control station F equipped with a F1 video camera that views an area of BAS film to control the quality of the making.
