- the presses used in the process of the invention are the conventional presses in the field of laminate manufacture.
- the humid atmosphere is preferably air at a relative humidity RH> 5%, preferably RH> 10% and better RH> 20%.
- a plasma is an electrically neutral gas whose species, atoms or molecules, are excited and / or ionized.
- a cold plasma is an ionized gas, in a state of thermodynamic non-equilibrium, of which only the electrons are carried at high temperature the other particles (ions, radicals, fragments of molecules, neutral neutrals) remaining at ambient temperature.
- cold plasmas are media that allow surface modifications (deposits, grafting, etching, etc.) at low temperature, without altering the substrates.
- the plasma is generated in a confined chamber, under a partial vacuum or at atmospheric pressure, into which a piasmagene gas is injected.
- a discharge that is a rapid conversion of electrical energy into kinetic energy, and energy excitation and ionization of atoms and molecules.
- the electrical energy supplied to the system is partly converted by the charged particles thus formed (electrons, ions) into kinetic energy. Because of their low mass, the free electrons generally recover the bulk of this energy and cause, by collisions with heavy particles of gas, their excitement or dissociation and therefore the maintenance of the ionization
- Plasma treatment is mostly used to improve the wettability
- the oxidizing plasmas (C> 2 , CO 2, H 2 O ) give rise to the formation of oxygenated functional groups (hydroxyl, carbonyl, carboxyl, peroxide, hydroperoxide, carbonate ). Functionalization of the surfaces with hydrophilic groups of this type makes it possible to increase their softness and, in principle, their adhesion ability.
- Oxidizing and reducing plasmas and in particular O 2 piasmas are commonly used to remove traces of organic contaminants on the surface of polymeric substrates as well as fragments of the polymer. (o ⁇ gomers) weakly bound present on the surface of these same substrates.
- pre-cleaning plasma it is a plasma treatment as described previously. The plasma oxidation leads to the dissociation of these species and the desorption of volatile compounds (CO, CO2, H2O ...) which are eliminated by your reactor pumping systems.

- Germanium allows the analysis of a depth of about one micron. It is therefore suitable for the analysis of very weak deposits.
- the blank spectrum is carried out with the clean crystal
- the deposition or exudate spectra were measured on non-exuding, weakly exuding and exuding polymer (see FIG. 1).

- Laminates were made as follows:
- an N2 / O2 plasma pre-cleaning is carried out in the case of Example 24 or a chemical pre-cleaning with MEK in the case of Comparative 22 or a pre-cleaning with soapy water in the case of Comparative 23;
- an aqueous adhesive (Dongsung W-01®) is applied to the surface of the substrate (A), previously covered with aqueous primer and dried in a ventilated oven (5 minutes at 70 ° C.),
- the two substrates are docked at their glued surfaces and the whole is pressed under air for 1 minute at a pressure of 4 bar and at room temperature.
