DECORATIVE DESIGN ELEMENT IN BLACK PRINT

Description

[0001] The invention relates to a laminated glass having a design element and a method for producing this laminated glass. The laminated glass is particularly suitable as a vehicle window.

[0002] The use of smart features such as Wi-Fi is becoming increasingly important in automobiles. To indicate that the vehicle has such a feature, a design element is often applied to a vehicle window. Other information, such as product information, is also applied to vehicle windows as a design element.

[0003] Currently, such design elements on vehicle windows are created by a black print with non-print areas, creating an image composed of black print and non-print areas. Plain panes and laminated glass used as vehicle windows are transparent due to their function. Accordingly, the lamination layers used in laminated glass are transparent or clear. Therefore, the design elements exhibit only low contrast. The result is poor visibility of the design element. This means that the design element is only recognizable at a very short distance, very close to the laminated glass.

[0004] There are known methods for increasing contrast that involve an additional screen print in a light color. However, this requires an additional process step and additional screen printing equipment, and is more complicated, costly, and requires significant modifications to existing production lines. The accuracy of the various prints produced can also be a problem.

[0005] DE 10 2008 017 895 A1 discloses a laminated glass pane in which a negative of the future visible logo is applied to the inside of an outer pane using a screen printing process. In the area of ​​the logo, a viewing film is bonded to the adhesive layer that holds the two panes of the laminated glass pane together. This is intended to achieve a high-quality logo. A disadvantage of this solution is that air pockets can form in the area of ​​the viewing film between the viewing film and the pane during lamination, which impairs the representation of the logo.

[0006] The invention is therefore based on the object of providing a laminated glass with a design element in which the design element has higher contrast and thus offers improved visibility. Furthermore, the laminated glass with the design element should be capable of being manufactured in a simple and cost-effective manner.

[0007] This problem was solved in particular by incorporating an opaque, non-black base into the film composite of the laminated glass to underlie the design element located on one side of the pane.

[0008] The object of the present invention is therefore achieved by a laminated glass according to claim 1 and a method for producing the laminated glass according to claim 12. Preferred embodiments are evident from the subclaims.

[0009] By incorporating the opaque, non-black underlay, it is possible to highlight the non-printing areas of the design element with a strong contrast to the black print areas, thereby significantly improving the visibility of the design element. By selecting the color of the underlay, the strength of the contrast and the appearance of the design element can be adjusted as desired. Furthermore, this is a relatively simple and cost-effective process measure that does not require major changes to existing production lines.

[0010] Accordingly, the present invention relates to a laminated glass 18 comprising an outer pane 5, an inner pane 6, at least two laminating layers 7, 8 arranged between the outer pane 5 and the inner pane 6, and at least one design element 9, wherein the design element 9 is formed on a partial area of ​​a pane side of the outer pane 5 or the inner pane 6 from an image-based black print 15 with one or more print-free areas 16 and an opaque, non-black base 10 is arranged between the two laminating layers 7, 8 and is underlaid with the print-free area(s) 16 of the design element 9.

[0011] The invention is explained below and in the accompanying figures. These show: Fig. 1 shows an example of a design element, Fig. 2 shows an exploded view of a laminated glass according to the invention, Fig. 3 shows an example of a further design element for a WiFi function, Fig. 4 shows an exploded view of a section of a further laminated glass according to the invention, showing the partial area on which the design element is arranged, Fig. 5 shows an oblique view of a laminated glass according to the invention with three design elements.

[0012] The laminated glass comprises an outer pane and an inner pane, which are laminated to form a solid composite by at least two laminating films in between.

[0013] For the purposes of the invention, the inner pane refers to the glass pane that, when installed, e.g., in a vehicle or building, is intended as the pane of the laminated glass facing the interior, e.g., a vehicle interior or a living space. The outer pane refers to the glass pane that, when installed, e.g., in a vehicle or building, is intended as the pane facing the exterior.

[0014] Laminated glass, especially for vehicle windshields, can be flat or curved. In flat laminated glass, the inner and outer panes are flat. In curved laminated glass, the inner and outer panes are curved. Curved laminated glass is used, for example, as windshields or rear windows in vehicles.

[0015] The inner pane and the outer pane can be made of the same material or of different materials. The inner pane and the outer pane can be made of inorganic glass and / or organic glass (polymers), with inorganic glass being preferred. In a preferred embodiment, the inner pane and / or the outer pane contains flat glass, quartz glass, borosilicate glass, soda-lime glass, alkali aluminosilicate glass, polycarbonate, and / or polymethacrylate. The inner pane and the outer pane are preferably made of soda-lime glass.

[0016] The inner pane and the outer pane can have the same thickness or different thicknesses. Preferably, the inner pane and the outer pane independently have a thickness in the range of 0.4 to 5.0 mm, e.g., 0.4 to 3.9 mm, more preferably 1.6 to 2.5 mm. For mechanical reasons, the outer pane is preferably thicker than or equal to the inner pane.

[0017] The inner and outer panes can be clear or tinted. Tinted panes are preferably gray or dark gray. The inner and outer panes are preferably clear. Tinted panes are preferably green.

[0018] The inner pane and / or the outer pane may have other suitable, conventional coatings, e.g., non-stick coatings, tinted coatings, infrared-reflecting coatings, e.g., in the form of a metallic coating, anti-scratch coatings, or low-emissivity coatings. An example of coated glass is low-emissivity (LEE) glass.

[0019] In a preferred embodiment, both panes of glass are clear, and the inner side of the outer pane (side 2) or preferably the outer side of the inner pane (side 3) is provided with an infrared-reflecting coating, in particular a metal coating. In an alternative embodiment, both panes of glass are clear, and an infrared-reflecting film, in particular a metal-coated film, is provided in the composite.

[0020] The laminated glass further comprises two or more lamination layers between the inner and outer panes. The at least two lamination layers may be identical or different. The lamination layers each extend substantially over the entire surface of the laminated glass. The following information refers independently to all of these at least two lamination layers, unless otherwise stated.

[0021] The lamination layer is, in particular, a polymeric lamination layer. The lamination layer preferably contains a thermoplastic polymer. Commercially available lamination films are typically used as the starting material for forming the lamination layers. They are used to bond or laminate the components of the vehicle window to create the adhesive glass composite.

[0022] The laminating layer may contain, for example, polyvinyl butyral (PVB), ethylene-vinyl acetate, polyurethane, polypropylene, polyacrylate, polyethylene, polycarbonate, polymethyl methacrylate, polyvinyl chloride, polyacetate resin, casting resin, acrylate, fluorinated ethylene-propylene, polyvinyl fluoride, and / or ethylene-tetrafluoroethylene, and / or a mixture and / or a copolymer thereof. Preferably, the laminating layer contains polyvinyl butyral (PVB), ethylene-vinyl acetate, polyurethane, and / or mixtures and / or copolymers thereof, with PVB laminating layers being particularly preferred.

[0023] The laminating layers, preferably PVB laminating layers, each preferably have a thickness of 0.04 to 1.5 mm, more preferably 0.1 to 1.2 mm, even more preferably 0.3 to 0.9 mm.

[0024] In particular, the lamination layer arranged between the design element and the substrate is transparent, and can preferably be clear, i.e., colorless, or tinted. Tinted lamination layers are preferably gray, blue, or green. The lamination layer between the design element and the substrate is preferably clear, as this best emphasizes the contrast of the design element achieved by the substrate. However, the use of a tinted lamination layer is also possible if a special optical effect is desired for the design element.

[0025] The lamination layers not located between the design element and the substrate are also preferably transparent, and may be clear or tinted. Tinted lamination layers are preferably tinted gray, blue, or green.

[0026] The laminated glass has at least one design element. The design element is formed on a partial area of ​​one side of the outer pane or the inner pane, consisting of a pictorial black print with one or more non-printing areas.

[0027] The pane side of the outer pane or the inner pane can be one or more of the outer side of the outer pane, also referred to here as side 1, the inner side of the outer pane, also referred to here as side 2, the outer side of the inner pane, also referred to here as side 3, and the inner side of the inner pane, also referred to here as side 4.

[0028] In preferred embodiments, the side of the disc on which the design element is printed is side 2 and / or side 4, wherein the side of the disc on which the design element is printed is particularly preferably side 2.

[0029] The design element is formed from an image-based black print with one or more non-print areas. Image-based black print with one or more non-print areas means that an image is created from the combination of one or more areas containing black print and one or more non-print areas. Accordingly, it is a monochrome print in which the image of the design element is represented by black-colored areas and blank areas. Such design elements formed from an image-based black print with one or more non-print areas are known in the art.

[0030] The image information can be derived from the non-printed areas or the black-colored areas, or a combination thereof. The image-based black print can be, for example, a stamp print, such as a product stamp, or a negative print, although this is preferably a negative print. The negative print is preferably left out in the black print.

[0031] The representation created by the design element can be, for example, characters, symbols, signs, graphic patterns, a logo, or combinations thereof. The design element can be suitable as a decorative design element.

[0032] Any black ink can be used for image-based black printing. Examples include black printing with black ceramic ink or other black printing inks, with black ceramic ink, also known as black enamel, being preferred. Image-based black printing is preferably screen printing with a black ceramic ink. This is the standard process in the industry.

[0033] In keeping with its function, the laminated glass has a see-through area where the laminated glass is free of black print. The see-through area of ​​the laminated glass generally represents at least 30%, preferably at least 50% of the laminated glass surface, e.g., for roof windows, but can also be significantly larger, at at least 70% or at least 80%, e.g., for windshields or rear windows. It is understood that the design element is present only on a portion of the laminated glass, and this portion lies outside the see-through area.

[0034] Otherwise, there are no fundamental restrictions on the size of the at least one design element. One or more design elements can be present.

[0035] The design element can be arranged anywhere on the laminated glass. It is preferably located near the edge of the laminated glass. However, it is generally preferred that the design element be at least 10 mm away from the edge of the laminated glass.

[0036] The laminated glass according to the invention further comprises an opaque, non-black underlay arranged between the two lamination layers so that it underlies the non-printing area(s) of the design element. The term "underlay" here means that the underlay is located behind the non-printing area(s) of the design element, relative to the intended viewing direction of the design element. The intended viewing direction is from outside to inside for a design element on an outer side of the pane and from inside to outside for a design element on an inner side of the pane. In this way, the underlay is visible through the non-printing areas in the intended viewing direction, resulting in greater contrast.

[0037] While the lamination layers are generally present over the entire area of ​​the laminated glass, the substrate is only present in a partial area of ​​the laminated glass.

[0038] The size of the underlay can be the same as the size of the design element. However, the size of the underlay can also be smaller than the size of the design element, provided that all non-printing areas of the design element can be underlaid with the underlay. The underlay is preferably at least slightly larger than is necessary to underlay the non-printing areas of the design element. This can be useful so that any inaccuracies in positioning do not immediately result in some of the non-printing areas not being underlaid by the underlay. A slightly larger size of the underlay can also be useful to improve the handling of the piece of film forming the underlay. The underlay can also be larger than the design element if necessary, e.g. if the design element is surrounded by full-surface black printing as described below.However, the base should be positioned and dimensioned in such a way that it does not protrude into the see-through area of ​​the laminated glass.

[0039] The size of the base thus depends essentially on the size and type of design element. The area of ​​the base can, for example, be no more than 70%, preferably no more than 50%, more preferably no more than 20%, and in particular no more than 5%, preferably no more than 2%, of the area of ​​the laminated glass. This also depends on the use of the laminated glass. For example, relatively large design elements are conceivable for a roof pane, while smaller design elements are preferred for rear or windshield windows. The number of bases generally corresponds to the number of design elements present.

[0040] The geometry of the base is arbitrary. In practice, rectangular bases are suitable, for example. However, the geometry can also be adapted to the geometry of the design element and can be circular or irregular, for example.

[0041] The underlay is a sheet material. Since the underlay is only applied to a portion of the laminated glass, thickness variations occur within the laminated glass. To avoid excessive thickness variations in the laminated glass, the underlay should not be too thick. On the other hand, handling the piece of film forming the underlay may be difficult if the underlay is too thin.

[0042] In general, it is therefore advantageous if the substrate has a thickness in the range of 1 to 120 µm, preferably 10 to 100 µm and more preferably 20 to 70 µm.

[0043] The base is opaque and non-black. The base color can be selected as required. Any non-black color is possible. Preferably, a color that provides a strong contrast to the black print is chosen. The opaque base is preferably white. A white base provides the strongest contrast, optimizing the visibility of the design element.

[0044] The opaque substrate is preferably a plastic substrate, especially a flat plastic substrate. This is usually formed from a corresponding piece of film. The plastic substrate usually contains coloring agents, e.g., pigments, to achieve opacity and color.

[0045] The opaque base may, for example, be formed from a polymer, in particular a thermoplastic polymer such as polyethylene terephthalate (PET), which forms the main or sole component of the base matrix. In addition to the polymer mentioned, the base may contain other polymers and additives as are customary in the art. Examples of additives are colorants such as pigments, UV stabilizers, fillers, and the like. As stated above, the base typically contains colorants, such as pigments, to impart opacity and color.

[0046] The opaque, non-black backing is particularly preferably made of PET, with a white PET backing being particularly preferred. PET backings are particularly preferred because thin PET films are available in the desired backing thickness range, and PET exhibits good compatibility with the laminating layers, especially the PVB laminating layers.

[0047] The laminated glass can also have a full-surface black print, preferably on the side edge of the laminated glass and preferably running around the entire side edge of the laminated glass. Laminated glass, particularly laminated glass for vehicle windows, is often provided with a full-surface black print on the side edge to visually conceal certain elements required for installation in a vehicle or structure, such as adhesive joints.

[0048] Full-surface black printing can be performed using the same processes and inks described here for image-based black printing, to which reference is made. Screen printing with black ceramic inks is also common and preferred for full-surface black printing.

[0049] In a preferred embodiment, the design element is surrounded by a full-surface black print, wherein the full-surface black print is preferably formed in an edge region of the laminated glass, wherein the full-surface black print particularly preferably runs around the entire edge region of the laminated glass. In this case too, it is generally preferred for the design element to be at least 10 mm away from the edge of the laminated glass. If the design element is contained in a full-surface black print, it is usually expedient to print the design element and full-surface black print in one step on the same side of the pane, wherein the pane side is preferably side 2 and / or side 4, more preferably side 2.

[0050] In a preferred embodiment, the disc opposite the disc having the design element has a congruent position with respect to

[0051] The design element can be the same design element, a different design element, or a full-surface black print. This is advantageous for obscuring the view of the opaque backing from a direction that is not the intended viewing direction for the design element. If the design element is the same or different on the opposite pane, this also ensures that the design element can be viewed from both inside and outside.

[0052] The laminated glass may optionally further comprise one or more additional functional layers, particularly polymeric functional layers, between the outer pane and the inner pane. Such additional functional layers are known in the art. Typically, commercially available functional films are used as the starting material for forming the functional layers.

[0053] Examples of optional additional functional layers are acoustic layers or IR-reflecting layers. IR, as usual, is an abbreviation for infrared. If additional functional layers are included, they are preferably arranged between two lamination layers. The functional layers can each have a thickness in the range of 0.04 to 1.5 mm, preferably 0.1 to 1.5 mm, and more preferably 0.3 to 0.9 mm.

[0054] Acoustic layers, for example, are composed of several, say three, PVB layers, with a softer PVB layer in the middle. Since the acoustic layers are also suitable as lamination layers, they can serve a dual function.

[0055] IR-reflecting layers are formed, for example, from a polymeric carrier layer and an IR-reflecting coating located thereon. The polymeric carrier layer can be formed, for example, from polyester, polycarbonate, cellulose acetate, acrylate or polyvinyl chloride. The IR-reflecting coating can fundamentally be designed in different ways and preferably comprises at least one silver layer. Multilayers with one or more silver layers as the actual functional layer, which are embedded between metallic and / or dielectric layers, are generally common. As explained above, IR-reflecting coatings are additionally or preferably alternatively conceivable directly on the inner or outer pane, for which at least one silver layer or the aforementioned multiple layers can also be used.

[0056] In general, it is preferred that only one lamination layer be present between the substrate and the pane bearing the design element. However, more than one lamination layer and / or one or more functional layers may be arranged between the substrate and the pane bearing the design element, provided that these layers are each transparent. However, this is less preferred.

[0057] The laminated glass according to the invention is particularly suitable as a vehicle window or as building glazing. The laminated glass is particularly preferably a vehicle window, in particular an automobile window, e.g., a roof window, a side window, a windshield, or a rear window.

[0058] The invention further relates to a method for producing a laminated glass according to the invention as described above, the method comprising the following steps: a) image-wise printing of a black ink onto a partial area of ​​one side of a pane, whereby a design element 9 is formed from a black print with one or more non-printing areas, b) providing an assembly which comprises, in this order, an outer pane 5, a first laminating film 8, a second laminating film 7 and an inner pane 6, wherein the pane with the design element 9 obtained in step a) is used for the outer pane 5 or the inner pane 6 and wherein an opaque, non-black piece of film is positioned between the two laminating films 7, 8 such that it is underlaid as a base 10 under the non-printing area(s) 16 of the design element 9 in the finished laminated glass 18, and c) heat-treating the assembly obtained in step b) to laminate the assembly to form the laminated glass.

[0059] All the above statements for the laminated glass according to the invention also apply accordingly to the process according to the invention.

[0060] The image-based printing of the black ink can be carried out using screen printing, inkjet printing, or laser transfer printing, for example, although screen printing is preferred. All conventional inks are suitable as black inks, e.g., ceramic ink or other printing inks, although ceramic ink is preferred. Image-based printing is preferably carried out using screen printing with black ceramic ink. If the design element is surrounded by full-surface black printing, preferably running around the side edge of the laminated glass, the image-based printing and full-surface black printing can be printed together in a single step, e.g., using screen printing.

[0061] Depending on the printing ink used for the design element, a heat treatment may also be necessary to bake the printing ink, especially when ceramic or enamel inks are used. The heat treatment for baking can be carried out at temperatures ranging from 400°C to 700°C, preferably 550°C to 650°C, especially when printing with a ceramic ink. The required heat treatment or baking of the black print is usually performed after printing and before arranging and laminating the laminated glass.

[0062] In step b), the opaque, non-black piece of film is positioned between the two laminating films so that in the finished laminated glass it acts as a base for the non-printing area(s) of the design element.

[0063] In a preferred embodiment, the opaque film piece is pre-fixed to one of the two laminating films in step b) after positioning. This is preferably done by heat treatment, e.g., using a hot air gun. The positioning and, if necessary, pre-fixing of the opaque film piece on a laminating film can take place before or after the laminating film has been applied to the assembly to be formed.

[0064] The above information regarding the substrate applies equally to the opaque film piece, particularly with regard to dimensions, thickness, and type, so reference is made thereto. Accordingly, the opaque film piece is preferably a PET film piece, in particular a white PET film piece.

[0065] The assembly is laminated using a heat treatment, which can be performed under atmospheric pressure, negative pressure, or positive pressure. The assembly can be laminated in air or in a protective gas atmosphere, for example. A person skilled in the art is well-versed in the appropriate processes and conditions.

[0066] The heat treatment of the assembly obtained in step b) for laminating the assembly is carried out according to known standard methods, e.g. at temperatures not exceeding 200 °C, e.g. in the range of 80 to 150 °C.

[0067] The invention will be further explained below using non-limiting embodiments with reference to the accompanying drawings. The drawings are schematic and not to scale.

[0068] Fig. 1 shows an example of a design element 9, in which the non-printing areas 16 represent lettering and symbols in a black print 15. The design element is formed as a negative print. A white underlay (not shown) provides good contrast and visibility.

[0069] Fig. 2 shows an exploded view of a laminated glass 18 according to the invention, which has a design element 9 according to Fig. 1 The laminated glass has an outer pane 5 and an inner pane 6, between which two lamination layers 7, 8 are arranged. The two lamination layers 7, 8 are both clear PVB lamination layers, for example, with a thickness in the range of approximately 0.3 to 0.9 mm. The design element 9 was printed image-wise on a partial area of ​​the inner side 2 of the outer pane 5 (side 2). This was done by screen printing with a black ceramic ink. An opaque, white PET underlay 10 is arranged between the two lamination layers 7, 8 in such a way that it underlies the non-printing areas of the design element 9. The dimensions of the underlay are smaller than the dimensions of the design element 9, but slightly larger than would be required for underlaying the non-printing areas of the design element 9. The dimensions of the design element can be, for example, approximately 200 x 300 mm, but smaller or larger dimensions are equally possible. The thickness of the underlay is, for example,in the range of 20 to 70 µm, e.g., approximately 50 µm. The white background provides good contrast and visibility for the design element.

[0070] Fig. 3 shows an example of a design element with a symbol for a Wi-Fi function. The Wi-Fi symbol is represented by black print surrounded by a non-printing area, which in turn is framed by black print. A white underlay (not shown) provides good contrast and visibility.

[0071] Fig. 4 shows an exploded view of a section of another laminated glass 18 according to the invention, which shows only the partial area on which a design element is arranged. The design element 9 with black print area 15 and print-free area 16 corresponds to the design element of Fig. 3 , except that there is no WiFi symbol inside. The section of the laminated glass shows a portion of the outer pane 14 and a portion of the inner pane 11, between which portions of two lamination layers 12, 13 are shown. The two lamination layers 12, 13 are both PVB lamination layers, with the lamination layer 13 located between the outer glass and the substrate being clear and the lamination layer 12 located between the inner glass and the substrate being tinted. The design element 9 was printed image-wise on the portion of the outer glass and congruently on the portion of the inner glass, more precisely on the inner side of the outer pane 14 (side 2) and the inner side of the inner pane 11 (side 4). This was done in each case by screen printing with a black ceramic ink. An opaque, white PET base 10 is arranged between the partial areas of the two laminating layers 12, 13 in such a way that it underlies the non-printing areas of the design element 9.The dimensions of the base 10 correspond to the dimensions of the design element 9. The thickness of the base 10 is, for example, in the range of 20 to 70 µm, e.g., approximately 50 µm. The white base provides good contrast and good visibility for the design element.

[0072] Fig. 5shows an oblique view of another laminated glass 18 according to the invention with three design elements 9 (top view of the outer pane). The laminated glass has a full-surface black print 15 running around the entire edge region of the laminated glass. The three design elements 9 are formed in the full-surface black print and surrounded by it. The full-surface black print and the three design elements 9 were printed together in one step by screen printing with black ceramic ink on side 2 of the laminated glass. The central area of ​​the laminated glass without black print represents the see-through area of ​​the laminated glass. On side 4 of the laminated glass, a full-surface black print can optionally be printed that is congruent with the full-surface black print from side 2, but without design elements.The dotted borders 17 around the design elements 9 are not actual dotted borders of the laminated glass, but are intended to indicate the position and dimensions of the respective underlying white underlay, which is located within the laminated glass and is not visible in this representation.
