Abstract

According to the inventive method for decorating the surface of a substrate, a coating agent which can be at least partially cured by irradiation with energy-rich radiation (e.g. light) is applied to the substrate surface to be decorated and the uncured coating layer is irradiated with energy-rich radiation in at least the area or areas to be decorated through one or more masks, these masks being permeable to energy-rich radiation and having structures which are set 100 to 20000 nm apart and which are less transparent or impermeable to energy-rich radiation. The areas in the coating layer that have not yet been cured are then cured thermally and/or with energy-rich radiation.

Description

A process for the decorative design of a painted substrate surface

The invention relates to a method for the decorative design of a painted substrate surface as well as the substrates obtained by the process. The inventive method may in particular find application in the decorative surface design of vehicle bodies, their components and vehicle parts.

In particular in the field of automotive finishing diverse examples of decorative surface finishes are known. For example, these include individual finishes, for example, effect coatings, finishes in special colors or coatings in the form of images, patterns or ornaments, but also the application of correspondingly designed adhesive films.

The object of the invention is to provide a method for the decorative design of a painted substrate surface. The method is intended to allow industrial or artisanal in the varnishing goods, including sporting goods, equipment housing and particularly in the field of vehicle and vehicle part coating, the generation of unique and impressive decoration effects.

It has been found that this object can be achieved by a subject of the invention method for the decorative design of a substrate surface, which is characterized in that a by irradiation with high-energy

Radiation applied at least partially curable coating composition to the substrate surface and the uncured coating layer comprise at least at the or areas to be decorated by one or more permeable for energy radiation masks spaced in the range 100-20000 nm of one another for high-energy radiation is less permeable or impermeable structures irradiated with high energy radiation and then not yet uncured areas in the coating layer is cured thermally and / or with high-energy radiation. In the context of vorleigenden invention, the term "of high energy radiation transmissive masks spaced in the range 100-20000 nm of one another for high-energy radiation is less than or impermeable structures comprising," naturally also include the reverse case, namely the use of impermeable to high-energy radiation masks in the range 100-20000 nm apart from each other have partly or wholly permeable structures for energy radiation.

The masks are held for example in a small distance above the coating layer or in each case or with the one flat side is brought directly into contact with the coating layer, without producing microstructures mechanically in the coating layer.

As high-energy radiation, for example light, preferably having a wavelength of 180-1000 nm. It will then be transparent masks with less translucent or opaque structures. In the following, for simplicity, to irradiation with light, reference is made however in principle also include the irradiation of other high-energy radiation is to be understood.

Subsequently, (n) each of the plural used for simplicity with respect to the mask (s) and the object to be decorated (n) position. At this point it should be noted that the term "(n) to be decorated body" also includes the special case of a full surface to be decorated substrate surface.

As a theory, without discharging a binding explanation, it is assumed that areas of different refractive index in the surface of the coating layer produced from the at least partially radiation curable coating compositions are produced by means of the partially light transmissive masks and / or micro-structures form on the surface. Further, it is believed that the differences in refractive index and / or the microstructures to light diffraction and

cause interference phenomena and are responsible for the perceived by the viewer decorative effect of the inventively designed surfaces. The viewer perceives through the irradiated through the partially light transmissive masks points true as decorative elements.

To create regions of different refractive index and / or different microstructures in the surface of the coating layer produced from the at least partially radiation curable coating composition by means of the partially light transmissive masks, the procedure can be such that the irradiated through the partially light transmissive masks through portions of the plating layer at the irradiation can not be completely cured and complete cure both the irradiated and then also takes place of the non-irradiated regions, in particular by irradiation. Alternatively, the procedure can be such that the irradiated through the partially light transmissive masks through portions of the plating layer can be completely cured upon the irradiation, and the complete curing of the non-irradiated regions is then carried out under different conditions, for example thermally or by means of irradiation under different irradiation conditions as in the previous irradiation step, z. B. Other irradiation time, wavelength and / or intensity of irradiation.

The inventive method is suitable for the decorative design of a plating layer, for example, manufactured goods such. B.

Facade elements, furniture, equipment housing, household appliances, sporting goods, eg. B. skis, surfboards, in particular automotive bodies and their parts as well as generally to vehicle parts. For example, it may be decorative plating layer to be designed to a coat or a layer applied in a multi-layer coating visible for the viewer of the plating layer at. The goods provided with the coating layer itself can be pre-coated, for example, wood, glass, but in particular of metal or plastic and, if appropriate, already with one or more coating layers.

The methods used in the present invention by irradiation with light at least partially curable coating agent no restriction in principle, they may be aqueous, diluted with solvents or preferably free from solvents and water to be. They can also be pulverformig. It may be at irradiation with light partially or preferably completely curable coating agent. In the curable by irradiation with light coating agents are in particular the known in the art cationically and / or radically curing coating agents. radically curing coating compositions are preferred. Upon exposure to high-energy radiation on applied from these coating agents overcoat layers originate in the overcoat layers radicals which cause crosslinking of the overcoat layers by radical polymerization of olefinic double bonds.

The preferred free-radically curable coating compositions comprise prepolymers, such as polymers or oligomers, the free-radically polymerizable olefinic double bonds, particularly in the form of (meth) acryloyl groups in the molecule. The

The methods used in the present invention by irradiation with light at least partially, curable coating compositions can be pigmented or colorless transparent or colored transparent. Preferably it is colorless or clear coats to color and / or effect-imparting coating agent, z. B. basecoats.

The at least partially curable by irradiation with light coating compositions may be applied by conventional methods, for example by spray application to substrates to be decorated. Application can be to the entire substrate surface or on one or more partial areas thereof, or only to the points to be decorated of the substrate surface, for example in a dry layer thickness of 5 to 250 microns.

After application and a flash-off phase, optionally granted or

Melting phase, the uncured coating layer at areas to be decorated with one or more per se light transmissive masks in the range 100-20000 nm, preferably spaced 800 to 20000 nm from each other, have less light transmissive or opaque structures, at a small distance, e.g. of generally not more than 2 cm, preferably not more than 2 mm, or respectively to the or a flat side of the light transmissive se masks in direct contact covered. In the latter case, a light-transmitting release film between the mask and uncured coating layer may be applied to facilitate the subsequent detachment of the mask.

The partially light-transmissive acrylate in the range 100-20000 nm, preferably spaced 800 to 20,000 nm apart, less light-transmitting or hchtundurchlässige structures having masks made of glass or preferably of transparent plastics, such as polyester, polycarbonate, polystyrene, poly (meth) or silicone plastic made. Preferably, the masks made of flexible, optionally elastic plastic. In order to facilitate the detachment of used in direct contact with the uncured coating layer of mask areas to be decorated after the irradiation, the masks on the corresponding flat side can expediently be specially equipped. This equipment can for example be that the mask material comprises, as such, for example due to corresponding additives, anti-stick properties, or the mask surface is provided with a non-stick coating.

The masks have areas of different light transmission. The translucent se masks have in the range 100-20000 nm, preferably from 800 to to 20000 nm spaced less translucent or opaque structures. In the less light transmissive or opaque structures, it may be an uncharacterized by spaced from each other in the range 100-20000 nm, preferably from 800 to to 20000 nm Amplitudenrnaxima relief or is inherently contained within the mask structures, for example comparable to a photographic microfilm negative or -positive. The relief may have grooves, ridges and / or holes.

The generation of the reliefs, for example, by standard methods of microstructure technology, for example, be associated with etching techniques, photolithographic techniques or vapor deposition, and laser techniques. In carried in the range 100-20000 nm, preferably from 800 to to 20000 nm spaced

Amplitudenrnaxima characterized, preferably located on one side of the relief mask is those having an amplitude level in the range, for example between 100 and 5000 nm. The Amplitudenrnaxima may be present as dots, lines, or plateaus. In the case of the present as the plateau amplitude maxima, the distance refers 100-20000 nm, preferably from 800 to 20,000 nm between the amplitude maxima on the distance between adjacent platform edges or between a plateau edge and adjacent present as dots or lines amplitude maxima. The relief may have irregular structures or is regular structures, such as optical diffraction grating, for example, cross grating or in the simplest case, optical grating. The grid lines can not be located equidistant or equidistant. At different levels of amplitude maxima, the distance to the resulting from the regulatory clearance relates.

The production of the structures inherently located within the masks can be effected for example, by photomicrograph or photolithographic processes.

The structures inherently located within the masks can be in the form of points, lines or surfaces. In the case of the present as surfaces of structures, the distance refers 100-20000 nm, preferably from 800 to 20,000 nm between the structures on the distance between adjacent

Surface or boundary lines between a surface boundary line and adjacent present as dots or lines structures. The structures can be irregular or is regular structures, such as optical diffraction grating, for example, cross-grid or in the simplest case, optical grating. The grid lines can not be located equidistant or equidistant.

The masks can take on any surface areas, for example, of a few square centimeters to several square meters. The less translucent or opaque structures can extend over the whole surface of the masks. However, the less light transmissive or opaque structures can also extend only over a partial area of ​​the mask, wherein the outer contour line of the structured regions with the outer contour line of the masks may coincide. This results in a variety of design options for the masks. For example, the masks can have a structured framework and, optionally, within the structured framework further having also limited by contour lines structured or unstructured regions. Unstructured regions can be, for example, translucent or opaque. Because of the many possible variations in the design of the masks a variety of decorative elements can be produced on areas to be decorated, for example, pictures, ornaments, patterns, logos, symbols, initials, model names, etc ..

The uncured coating layer according to the invention, as already described above, on areas to be decorated with one or more light transmissive se masks in the range 100-20000 nm, preferably from 800 to 20,000 nm spaced less translucent or opaque structures in a short distance, for example of generally not more than 2 cm, preferably not more than 2 mm, or respectively to the or a flat side of the light transmissive masks itself covered in direct contact. Subsequently, the uncured coating layer is carried through the masks preferably with light of a WeUenlänge 180-1000 nm irradiated. It may be mono- or polychromatic light. Preference is given to ultraviolet light. . UV radiation sources with emissions in the wavelength range of 180 to 420 nm are preferred, more preferably from 200 to 400 nm Preferred examples of UV-radiation sources are optionally doped high-pressure mercury, -mitteldruck- and - niederdruckstrahier, gas discharge tubes, such as xenon low pressure lamps, black light tubes, UV flash lamps.

When high-energy radiation, for example electron beams can be used. It can be used conventional electron gun under conventional conditions familiar to the expert application.

The application process, technical details of the irradiation are known to the expert and require no further explanation. For example, the irradiation time is in the range of the duration of UV flash, for example, 1 millisecond to 5 minutes, depending on the irradiation method and the type of UV radiation sources. Preferred is a period of irradiation, that is, a real exposure time to the UV radiation of less than 5 minutes. After irradiation, the places to be decorated partially translucent masks are removed from areas to be decorated.

The present in the coating layer is not cured bodies are cured after the removal of the partially light transmissive masks thermally and / or by irradiation with high-energy radiation. The term "uncured locations in the plating layer" refers to those sites which have not been achieved during the irradiation by the partial light transmissive masks therethrough from the radiation. Furthermore, the term "uncured locations in the plating layer" also includes, if appropriate, outside the masks lying

Areas of a coating layer, which were covered during irradiation. lie in the plating layer also not yet hardened places before, when the plating layer has been prepared from a partially curable by irradiation with light coating material and / or when an insufficient for curing radiation dose has been applied to the coating layer.

An exclusive photochemical curing not yet hardened places in the coating layer comes into question when a preferred, has been used by irradiation with light completely curable coating agents for preparing the coating layer. When using an only partially curable by irradiation with light coating agent instead of or in addition to photochemical curing, thermal curing, preferably between 40 and 160 ° C is carried out, for example at temperatures between 20 and 180 ° C. The choice of conditions during the thermal curing depends, for example on the composition of by irradiation with light at least partially curable coating agent or the type of substrates to be decorated. The same applies to the photochemical curing.

Following the inventive method, a clear coat layer of a clear lacquer coating composition any or any transparent plastic film may be applied to the decorated sites or over the entire coated substrate surface. Particularly in connection with the application of a final clear coat layer, the inventive method can be used as a separate process step in a method for producing a multi-layer coating. For example, the decorative elements comprising layers of paint by the inventive process on unpainted or with a mono- or multi-layer paint are applied pre-coated substrates and provided with a final clear coat. It can thus be taken that the above-mentioned curing not yet hardened places in the serving of obtaining the decorative effect coating layer is carried out together with the curing of the final clear coat by photochemical and / or thermal route, depending on the nature of the generation of the final clear coat clear lacquer coating agent used.

The inventive method can preferably be carried out so that, as a clear lacquer coating composition is applied to dark, for example black, or dark, for example black-painted substrates by irradiation with light at least partially curable coating agent. On dark surfaces of the inventively obtainable effect is in fact very intensely. It is also possible as a curable coating agent, a color and / or effect coating agents such. to use as a base lacquer coating composition, which is preferably dark, particularly preferably pigmented black.

With the inventive method coated substrate surfaces can be provided with decorative elements which show a viewing-angle-dependent effect. Deviating from the prior art in the field of effect coating, for example metallic finish viewing-angle dependent light / dark and / or color flop can decorative elements are produced with the inventive method, the a novel viewing-angle-dependent flop effect, a so-called

Comprising "on / off" or, r Phantom "Flop. This term embossing is intended to illustrate that it is here a flop effect, which is characterized therefrom by a viewing angle dependent visibility or imperceptibility of the decorative elements or parts. From the perspective of the viewer to switch between perception and non-perception can in fact occur abruptly and without smooth transitions. The perception of the decorative elements is given only for a certain range of viewing angles. In this perception angle range the decorative elements to the human eye, for example, appear in all the visible spectral colors.

If the decorative elements are produced by means of irregular structures having masks, so the decorative elements as, for example, appearing in all spectral holographic image are perceivable. If the decorative elements in the simplest case by means of a having an optical grating mask been generated, then the decorative elements in the form of a continuous, for example, all spectral colors having spectrum perceptible, that is, for the viewer results in a rainbow-like effect.

The inventive method can also be applied to the part surface, and therefore decorative, more or less strong attenuation of the reflection behavior (anti-reflection) outer se gloss lacquer coating layers on substrates. The masks then have such high-energy radiation for less permeable or impermeable structures which are suitable to generate destructive interference in the plating layer.

The inventive method coated substrate surfaces can be designed impressively decorative. The inventive method can be particularly advantageously applied, for example in the automotive field, which includes both the design of motor vehicles and parts in the craft area as well as in the industrial area of ​​the original, in particular for example as an integrated step in the context of automotive OEM. In the original equipment can be, for example, a decorative design of the entire visible outer surface of a motor vehicle parts in the passenger compartment of a motor vehicle or an individual taking place according to customer's decorative design act, for example, the attachment of initials of the customer, etc., or it is a standard decorative design, for example the attachment of a company logo, a type designation or the decorative emphasis of edges or transitions between different regions of a body, for example, between adjacent vehicle parts, etc.. In small-scale range, it may also for example be a decorative design of the entire visible outer surface of a motor vehicle parts in the passenger compartment of a motor vehicle or an individual taking place according to customer's decorative design of a motor vehicle (partially) s or a repair already decoratively designed in a corresponding manner motor vehicle (partially) act e. The inventive method can be performed as a separate step or as an integral process step in a whole or partial coating in small-scale range, for example in a paint shop.

The invention is explained in more detail in the following example.

example

A coated with a commercial black basecoat sample plate (5 cm by 10 cm) is treated with a solvent-free 100% solids content having UN curable clearcoat in 100 .mu.m Νaßschichtdicke coated. A 3 mm thick glass plate which an image formed on one side by Chrombedampfung, a mask area of ​​2 cm by 2 cm ausmachendes grating comprises (width of the designed as a plateau grid lines: 8 microns, the amplitude height of the grating lines: 120 nm, equidistant spacing of the outer platform edges: 8 microns) is placed with its flat side to the uncured clearcoat layer. Subsequently, the whole, partly covered by the glass plate is clear coat layer with a UN flash lamp (3500 Ws) irradiated with 5 UN flashes at an interval of 4 seconds. Thereafter, the glass plate is removed and the irradiated part still uncured clearcoat layer 5 analogous to UN flashes. When seen in the white light is taken up in the clearcoat surface a 2 cm by 2 cm wide area as rainbow colors exhibiting spectrum true. On tilting the sample sheet the rainbow colored area from a certain viewing angle suddenly you will no longer true.
