Definitions
- the invention relates to luminous laminated glazing, of the type for automobiles or buildings, providing uniform lighting in the face, or according to decorative or informative patterns (for example a text), in one or more colors .
- the object of the invention was to provide a solution for extracting light from laminated glazing which, in the off state (off) of the lighting, is invisible on each side of the glazing. , Day and night.
- a luminous laminated glazing comprising at least a first sheet of glass and a second sheet of glass bonded to each other by an adhesive layer interlayer, a main face internal to the structure of the laminated glazing, of at least one of the two sheets of glass and/or at least one of the two main faces of the interlayer adhesive layer being coated with a layer of transparent ink, characterized in that the ink emits visible light under ultraviolet radiation.
- An ink of such nature emitting visible light under UV excitation, has, compared to a transparent ink diffusing visible light, that is to say extracting it, the ability to be much less visible, invisible from day or night, in the off state of the active glazing.
- fingerprints or equivalent marks are absolutely invisible under ultraviolet radiation.
- the glass sheets are chosen from sheets of mineral glass such as soda-lime, aluminosilicate, borosilicate, optionally hardened, thermally toughened, or chemically reinforced, and sheets of structural transparent polymer material such as poly(methacrylate of methyl) (PMMA) or polycarbonate (PC).
- sheet of structural transparent polymer material means a sheet capable of constituting on its own a monolithic glazing, of ensuring its mechanical strength, in particular, and having an elastic modulus of the order of 1500 MPa for example, in contrast to an intermediate adhesive layer, for example.
- the intermediate adhesive layer is chosen from a layer of polyvinyl butyral (PVB), thermoplastic polyurethane (TPU) or ethylene-vinyl acetate (EVA) copolymer.
- PVB polyvinyl butyral
- TPU thermoplastic polyurethane
- EVA ethylene-vinyl acetate
- the layer(s) of transparent ink comprise(s) areas and/or patterns emitting visible light of different colors.
- the luminous laminated glazing is curved.
- the luminous laminated glazing is a motor vehicle glazing chosen from a roof, optionally panoramic, opening, a windshield, a side glazing, a rear door glazing, a rear window or a backlight, or a building glazing such as veranda or facade.
- Another object of the invention consists of a method of manufacturing a luminous laminated glazing according to one of the preceding claims, characterized in that that it comprises the application on a main face internal to the structure of the laminated glazing, of at least one of the two sheets of glass and/or on at least one of the two main faces of the intermediate adhesive layer, of a layer of transparent ink, which emits visible light under ultraviolet radiation, then the drying of the transparent ink prior to the assembly of the luminous laminated glazing.
- EXAMPLE 1 By screen printing an interlayer sheet of polyvinyl butyral with an ink of the composition detailed in the table below, after assembly with two sheets of float soda-lime glass, a laminated glazing of high mechanical quality and with transparent printing, invisible day and night in the absence of exposure to ultraviolet radiation.
- the "touch dry" time of 10 min is short and compatible with a continuous line industrial process.
- the [OH] content of polyvinyl butyral corresponds to a mass percentage of poly(vinyl alcohol) of 18%.
- the wetting agent also acts as a plasticizer, that is to say it allows greater deformation of the printed ink film without degradation of its optical properties.
- This is dimethylcyclohexyl phthalate.
- the UV ink is taken from a UV-Fluorescent Felt, marketed by Molotow® (Germany) under the name FEUTRE PINCEAU UV FLUORESCENT PUMP SOFTLINER. It is a transparent, UV-fluorescent alcohol-based ink, which in this case, under UV radiation, emits blue light. There are some from the same supplier that emit a green, yellow orange or pink light.
- the surface tension modifier is a 2-ethylhexyl acrylate copolymer; it does not contain silicone.
- the thickness of wet ink deposited by screen printing is between 10 and 50 ⁇ m.
- the adhesion of the printed interlayer laminate is attested by the satisfaction of the "ball drop" tests (falling ball) according to regulation N ° 43, addendum 42, of the agreement E / ECE / 324, E / ECE / TRANS/505, concerning the adoption of uniform technical prescriptions applicable to wheeled vehicles, equipment and parts which may be fitted or used on a wheeled vehicle and the conditions for reciprocal recognition of approvals granted in accordance with these prescriptions.
- Example 1 The ink of Example 1 is screen-printed on a soda-lime glass substrate on a Thieme machine with a 147 X 52 full-face type screen of 90.48 mesh and then dried in an infrared oven at 160°C.
- UV lamp black light
- UV ink With illumination by an ultraviolet lamp (black light), a blue coloration is observed for the sample with the addition of UV ink.
- the sample without added UV ink does not react to UV lamp excitation.
- the Lumicam measurements belong to two categories.
- the Lumicam Spotmeter spot-meter
- Avg Average luminance value (cd/m 2 ) on the defined surface.
- StdDev Standard Deviation
- Tg avg Target average
- tg StdDev the standard deviation with respect to this average.
- a Hazemeter, haze-gard model plus 4725 from the BYK® brand is used. It controls a total transparency according to the methods of the international standards: ASTM D1003 - Standard method of test of haze and light transmission of transparent plastics.
- TL %) is Light Transmission (Transmittance)
- H %) is Blur/Haze (Haze)
- C %) is Sharpness/Clarity (Clarity).
- the substrate can be printed with transparent ink containing UV ink (also transparent in the absence of ultraviolet radiation) according to a decorative or informative pattern (pictogram, text) with excellent definition, which appears under ultraviolet radiation by re-emission of blue light in accordance with this pattern.
- the pattern thus produced diffuses visible light, which it is capable of extracting from the glass substrate.
- such an extraction of visible light increases the visibility of the fingerprints of the users of the glazing.
- the emission of visible light under UV occurs in a remarkable manner with total disappearance of these fingerprints, and perfect neatness of the printed pattern.
