Definitions
- the invention relates to a method for producing a printed decorative composite body.
- the composite is composed of several layers.
- the sequence of layers is characterized among other things by the fact that it contains a printed carrier material as well as printed gemstones.
- a printed decorative composite body can be produced by the method according to the invention, whose three-dimensional effect is formed by superposition of a printed substrate and printed gemstones.
- the Combination of a three-dimensional motif and gemstones opens up a multitude of aesthetic design possibilities.
- the subject of the present application is therefore a process for producing a decorative composite body, comprising the following steps:
- Figure 1 shows the schematic structure of the printed decorative composite body: the composite body contains an optional adhesive layer (A1), a substrate (A), a printed sub-motif on the substrate (B), an adhesive layer (C), gems (D), a second printed sub-motif (E) and the optional protective layer (F).
- A1 an optional adhesive layer
- A1 a substrate
- A a printed sub-motif on the substrate
- B an adhesive layer
- C an adhesive layer
- gems D
- E second printed sub-motif
- F optional protective layer
- the carrier material (A) in Figure 1 is a variety of materials.
- the support materials are well known to those skilled in the art.
- the carrier material can be rigid or flexible and can be selected depending on the field of application.
- a carrier material is, for example, wood, plastic, metal, glass, paper or ceramics.
- metallic support materials for example, aluminum or steel are suitable.
- Plastics are preferably used according to the invention.
- Plastics are materials that consist mainly of macromolecules.
- Suitable support material is, for example: acrylic glass (polymethylmethacrylate), polycarbonate, polyvinyl chloride, polystyrene, polyphenylene ether, polyethylene, poly (N-methylmethacrylimide).
- a frozen supercooled liquid which forms an amorphous solid
- a carrier material Both metallic and non-metallic glasses are suitable for this purpose.
- Paper which consists essentially of fibers of mostly vegetable origin and is formed by dewatering a fiber suspension, can also be used as a carrier material.
- the support materials are well known to those skilled in the art.
- a plastic film is preferably used according to the invention.
- the adhesive layer serves to adhere to an object to be decorated.
- the plastic film is versatile applicable because of their flexible nature.
- the following plastic films may be used, among others: plastic films of polyolefins such as polyethylene or polypropylene, polyvinyl chloride, polystyrene and its copolymers, polyesters, polycarbonate, cellophane and polyamide. Also bio-based plastics such as polylactide or cellulose acetate can be processed into films. Polyethylene terephthalate is also suitable for the production of films.
- thermoplastic polymer films are preferably used as the carrier material.
- Thermoplastic plastic films are flexible, in particular self-adhesive, plastic films which adhere to the object to be decorated by thermal treatment.
- Thermoplastic polyurethane films are, for example, suitable as thermoplastic polymer films.
- Polyurethanes are formed by polyaddition of isocyanates and polyols. They are characterized by a high elasticity, which is variable depending on the composition. Purely aliphatic polyurethanes are resistant to yellowing and are preferably suitable. Polyurethanes are also characterized by a high chemical resistance.
- Thermoplastic ethylene vinyl acetate films are also suitable as a carrier material.
- Ethylene vinyl acetate is a copolymer of polyethylene and polyvinyl acetate having good heat resistance and aging resistance. Depending on the proportion of the copolymerized vinyl acetate, the elongation at break property of the material can be varied over a wide range.
- the thermoplastic ethylene vinyl acetate support film may, for example, be the film 20,500 from Collano and the film ev-guard transparent from the company Folienwerk Wolfen.
- thermoplastic polyamide films are also usable. Films based on polyamides, which are polycondensation products of carboxylic acids and amines, are highly resistant to abrasion and chemically resistant. However, in textile applications repeated washings may cause clouding of the polyamide.
- Thermoplastic polyamide films are, for example, the film POLI-MELT 701 from Polytape and the film sold by Collano 34.208.
- Thermoplastic polyester films are also suitable as a carrier material. Examples of these are polycarbonate, polylactide or polyethylene terephthalate. They are characterized by resistance to water, dilute mineral acids and aliphatic organic solvents. However, polyesters have no good resistance to alkaline solutions and chlorinated solvents.
- Thermoplastic polyester films such as, for example, the film POLI-MELT 700 from Polytape and the film PKF 130 from Gluetex. Can be used as carrier film.
- the thermoplastic films are given by way of example only and are well known to those skilled in the art.
- the support material (A) on the visible side of the decorative composite body has a white cover layer in order to emphasize the effect of the motif.
- the white cover layer can be applied, for example, by printing on a white ink (vide infra).
- a motif (B) is printed on the carrier material (FIG. 1).
- printing motifs are any characters, numbers, symbols or other visual representations.
- the print motif on the carrier material is a partial motif of an overall motif that forms an overall motif with the second partial motif in method step (d).
- ink is preferably used.
- An ink is a colored liquid.
- Ink usually comprises a solution or dispersions of dyes or pigments in water or other solvents containing little or no binder.
- UV inks, solvent inks, water-based resin inks or so-called nanoinks are suitable.
- UV inks do not dry in the ambient air but are cured with ultraviolet light immediately after application.
- the color pigments are bound in a mixture of acrylate monomers, oligomers and photoinitiators. Upon exposure of the UV rays to photoinitiators, polymerization is initiated and thereby the applied UV ink is cured. When printing on glass adhesion promoters are necessary. UV inks have the advantage that they allow high production speeds due to UV curing.
- water-based resin ink can be used.
- the ink is mixed with resin and dissolved in water.
- the resin binds the color pigments and ensures adhesion to the surface of the printed material.
- the water evaporates during and after applying the water-based resin ink.
- Electro Inc inks are also usable. These inks contain electrically charged particles. A roller is electrically charged at predetermined locations and moves past an ink reservoir. The roller picks up the ink at the charged points, continues to move and delivers the ink to the material to be printed. These inks can only be printed on flat substrates.
- Solvent inks are preferred. Solvent inks are solvent inks that have no water base. They are resistant to mechanical erosion (scratches) and water. The solvent inks contain solvents such as alcohol, ethyl acetate or other carboxylic acid esters, toluene or xylene. These solvents evaporate very quickly during printing. This achieves rapid drying and strength. Solvent inks usually have very good resistance.
- UV solvent inks have a higher resistance to mechanical erosion (scratches) compared to UV inks.
- Nano inks are solvent inks that contain particles the size of which is in the nanometer range. As a result, this ink has excellent adhesion to the surface of the printed material. Nano inks are available, for example, from ESC.
- ECO Solvent inks from the company Contento UV inks from Swissqprint or Eco UV inks from the company Contento are also suitable as inks.
- the inks are given by way of example only and are well known to those skilled in the art.
- inks and printers are used by the same manufacturer because they are matched.
- Various printing methods are suitable for printing the substrate with an ink, for example screen printing or stencil printing in general. Stencils mask the motif for printing.
- the printing is preferably carried out by means of a digital printer.
- Digital printers are printing devices in which the print image is transferred directly from a computer to the printing device without the use of a static printing form. This has the advantage that very flexible and very efficient motives can be printed.
- Inkjet printers are particularly preferably used for printing.
- Inkjet printers are matrix printers in which a printed image is created by the targeted shooting or the deflection of small ink droplets. A matrix printer generates its print image by setting individual small pixels.
- the inkjet printers belong to the group of non-impact printers. Non-impact printers have the advantage that they work without impact and do not exert any mechanical pressure on the material to be printed. This advantage is particularly important when printing the gemstones (vide infra).
- the printing techniques are well known to those skilled in the art.
- An adhesive layer (C) is applied to the printed carrier material, for example a thermoplastic film, in process step (b) on the printed side of the carrier material (FIG. 1).
- the adhesive is essential for the adhesion of the gemstones in process step (c).
- the adhesive layer is preferably transparent and preferably has a transparency of at least 50%, more preferably of at least 80%, most preferably of at least 90%. Due to the transparency of the adhesive layer, the imprinted motif is more effective.
- Physically curing systems are solvent adhesives and hot melt adhesives.
- Solvent adhesives are polymers dissolved in a solvent which form a solid layer at room temperature due to the evaporation of the solvent.
- Hotmelt adhesives are solvent-free and solid at room temperature adhesives, which are applied in a molten state on a sticky surface, and on the still in the molten state, the gemstones are applied. Upon cooling, a solid, non-sticky layer forms, which encloses the gemstones in a form-fitting or cohesive manner.
- So-called pressure-sensitive adhesives can be applied to the carrier material as solvent-based adhesives or else as hot melt pressure-sensitive adhesives, to which the gemstones are then applied.
- Chemically curing adhesives are called reaction adhesives.
- the chemical reactions may be polymerization, polycondensation or polyaddition reactions. Basically, a distinction is made between two-component adhesives or one-component adhesives in the case of chemically curing adhesives.
- the adhesives mentioned are well known to the skilled person.
- Preferred adhesives according to the invention are epoxy adhesives. They are obtainable by polyaddition between oxiranes and nucleophiles, for example, amines, sulfides or anhydrides. They are available as one- or two-component adhesives and are characterized by high chemical and mechanical resistance. A disadvantage may be the known yellowing tendency of many epoxy compounds.
- an epoxy adhesive for example, Uhu® Plus Endfest 300 from Uhu® or DP190 transparent from 3M is suitable.
- acrylate adhesives Preferably used is the class of compounds of acrylate adhesives. They arise, inter alia, by radical polymerization. Acrylic adhesives have a very high transparency depending on the composition. Acrylate adhesives, such as PMMA or cyanoacrylates, are often applied in liquid form.
- ethylene vinyl acetate is also usable. Ethylene vinyl acetate is a copolymer of polyethylene and polyvinyl acetate having good heat resistance and aging resistance. Depending on the proportion of the copolymerized vinyl acetate, the elongation at break property of the material can be varied over a wide range. Ethylene vinyl acetate is used primarily as an aqueous pressure-sensitive adhesive dispersion or hot melt adhesive.
- polyamides are usable. They are often used as a film or granules. Polyamides are polycondensation products of carboxylic acids and amines. Polyamides are very resistant to abrasion and chemically resistant. In textile applications, repeated washing may cause the polyamide to become cloudy.
- Polyester is another class of adhesives which can be used according to the invention.
- Examples are polycarbonate, polylactide or polyethylene terephthalate. They are characterized by resistance to water, dilute mineral acids and aliphatic organic solvents.
- Silicones may be useful as adhesives in certain applications. They are polycondensation products of various protected siloxane oligomers. Silicones are preferably applied in liquid form and harden to a solid. Polyolefins may also be used for bonding. They are applied in particular in the form of hot melt adhesive films. Polyolefins are, for example, polyethylene or polypropylene and polyisoprene. Polystyrene and its copolymers / block copolymers as well as polybutadienes or cellulose acetate can also be used as adhesives. Particular preference is given according to the invention to adhesives from the group of polyurethanes. Polyurethanes are formed by polyaddition of isocyanates and polyols.
- Polyurethane adhesives are preferably applied liquid, but can also be melted depending on the composition as an additional film layer. Kleiberit 701.6 from Kleiber, Sikamelt 9675 from Sika, DP610 from 3M or Araldite 2028 from Huntsman, for example, are suitable as polyurethane adhesives.
- the adhesive layer has a layer thickness of about 50 to 500 ⁇ to achieve a good embedding of the gemstones in the adhesive layer.
- the most varied methods are suitable for applying the adhesive, for example painting by means of a doctor blade which resembles a rectangular spatula.
- the adhesive is painted onto the substrate with a squeegee.
- Another possibility is spraying with the help of spray nozzles.
- lamination is suitable. During lamination, a carrier material is usually thermally or by means of press with a Adhesive film connected.
- An alternative method of applying the adhesive is dip coating, in which the printed side of the substrate is dipped in the adhesive.
- adhesives can also be applied by means of printing processes, for example jet printing.
- the extrusion is used to apply the adhesive.
- viscous adhesives are continuously extruded under pressure from a forming orifice, such as a slot die, and applied to the substrate. The methods are well known to those skilled in the art.
- a plurality of gemstones are applied to the uncured or softened thermoplastic adhesive layer, see layer (D) in Figure 1.
- the gemstones can be sprinkled onto the adhesive layer, for example, and are often arranged as widely as possible.
- the gems are made of transparent or translucent glass or plastic. Glass is particularly preferred. Other materials, such as cubic zirconia or other gemstones, are also suitable.
- the gemstones can be mirrored or coated to allow additional visual effects.
- the gemstones are not limited in their shape, they can be round or square, for example. According to the invention, the gemstones are preferably faceted. Faceted gemstones support the decorative appearance.
- Gemstones may also differ in size.
- the use of differently sized gemstones results in an improved decorative appearance that supports the three-dimensional effect of the printed motif. Therefore, according to the invention, gemstones which have different sizes are preferably applied to the adhesive layer.
- the faceted article A.3498 made of glass with about 1 mm, with about 2 mm or about 2.8 mm in diameter.
- Plastic gemstones with a diameter of approx. 2.8 mm are available as article 5355-28 from the company Pracht®.
- Under the article number A.3499 obtained from the company D. Swarovski KG a mixture of gemstones of different shape: about 10% of the faceted article A.3498 with about 1 mm in diameter and about 90% of the Bailotini® glass ball A.3497 with approx. 1 mm diameter.
- the gemstones and optionally the adhesive layer in the interstices of the gemstones are printed with a motif (layer E in Figure 1).
- the Partial print motif on the carrier material and the partial print motif on the gemstones or the adhesive layer form the overall motif.
- the superposition of the two print motifs results in a three-dimensional effect.
- digital printers are preferred for printing on the gemstones, particularly preferably ink-jet printers.
- the plurality of gemstones on the adhesive layer often forms, for example, by the gemstone shape or the different gemstone sizes, an uneven surface.
- Inkjet printers do not require direct contact with the material to be printed (vide supra) and are therefore preferably suitable for printing on the gemstones.
- other printing methods such as screen printing, are suitable.
- Suitable inkjet printers are, for example, the flatbed printer CPD 640-1, 4XJ or the flatbed printer CDP 640-1.4 LEJ from Contento or the roller printer RHO 1012 from Durst, the roller printer GS3250 from EFI, the flatbed printer Impala 2 from Swissqprint , the inkcolour MIG 64 of the company ESC or the HP indigo of the company HP.
- the printers are given by way of example only and are well known to those skilled in the art.
- Suitable inks are, for example, ECO Solvent inks from the company Contento, UV inks from Swissqprint or Eco UV inks from the company Contento.
- the inks are given by way of example only and are well known to those skilled in the art.
- inks and printers are used by the same manufacturer because they are matched.
- a protective lacquer is applied as the protective layer.
- the protective lacquers preferably have a transparency of at least 50%, particularly preferably of at least 80%, very particularly preferably of at least 90%.
- varnish is understood as meaning a liquid or pulverulent coating material which is applied thinly to objects and is built up by chemical or physical processes, for example evaporation of the solvent, to form a continuous, solid layer. Paints often contain binders, fillers, pigments, solvents, resins and / or acrylates and additives. For the purposes of the invention, for example, acrylic lacquers, epoxy lacquers or polyurethane lacquers are suitable.
- Acrylic paints are manufactured on the basis of acrylic resins.
- Acrylic resins are synthetic resins and are considered particularly durable.
- Acrylic resins are based on polymers or copolymers of acrylic acid or methacrylic acid and their esters. They are often copolymerized with other unsaturated monomers, such as styrene or acrylonitrile.
- Acrylic paints are either dissolved in solvents or dispersed in water and applied to the coated gemstone mount.
- Acrylic coatings have a high weather resistance and are UV-resistant and are therefore preferred.
- acrylic lacquer for example, the 09852 Carbamid Clear from Lambaler is suitable.
- Epoxy paints often contain the two components epoxy resin and hardener.
- Epoxy resins are polyadducts of epichlorohydrin with bisphenol derivatives, for example A, F or S. These are crosslinked with a hardener. Usually, the two components epoxy resin and hardener are mixed shortly before processing. Epoxy resin coatings are characterized by a high chemical and mechanical resistance, but are often not sufficiently lightfast.
- Polyurethane paints are commercially available as one-component and multicomponent coatings; for example, in the one-component coating the curing agent is already mixed with the master paint, and in the two-component paint hardener and master paint are separated.
- Polyurethane varnishes are abrasion resistant and resistant to water, oils and chemicals. Preference is therefore given to using polyurethane coatings as a protective coating, for example Berlacryl 2K-PUR clearcoat 042.928.100 High abrasion resist from Berlac or Pigmotop G100 from Adler.
- the protective coatings are applied by spraying, for example.
- Preferred according to the invention are decorative composite bodies comprising (a) a printed carrier material,
- thermoplastic film with an inkjet printer or a part of an overall motif.
- the thermoplastic film has a side with a white topcoat and the motif is printed on the white topcoat.
- the specification of the motif is done by computer.
