Definitions
- the invention described below relates to a multi-layer, color and / or effect coating comprising a clearcoat and a basecoat and a method for forming the basecoat.
- Color and / or effect coatings usually comprise several layers of paint, which are applied over each other and have different properties.
- a primer layer (primer) and / or a surfacer coat a basecoat film and a clearcoat film are frequently applied in succession.
- the primer layer can be deposited, for example, electrically, in particular by means of electrocoating. It is often used to improve the adhesion of the paint on the substrate. In metallic substrates such as the aforementioned motor vehicle body, it also continues to serve corrosion protection.
- the filler layer serves to cover unevennesses of the substrate surface to be painted and, because of its elasticity, can improve a coating with regard to its resistance to chipping.
- the filler layer can serve to enhance the opacity and to deepen the color of the paint.
- the basecoat layer carries colors and / or angle-dependent optical effects of the finish. Both the brightness and the color of the reflected light can vary as a function of the viewing angle, which is also referred to as brightness and / or color flop.
- the clearcoat film serves to enhance the optical effects and protect the paint from mechanical and chemical damage.
- the color and the flop behavior of the basecoat film can depend very much on the conditions under which the basecoat film is applied to a substrate. This is particularly relevant if platelet-shaped dye and / or effect pigments are incorporated in the basecoat film. Their orientation within the basecoat layer can strongly influence the optical properties of the coating. If a basecoat layer is formed approximately by means of a coating method such as rolling or doctoring, the platelet-shaped pigments within the basecoat layer are oriented predominantly in a preferred direction, namely in the direction of the application. Basically, one speaks in the coating in all application processes in which the pigments are arranged without further action in a preferred direction of directed application process, in contrast to non-directionalMapver drive, in which the pigments are not arranged in a preferred direction.
- the basecoat layer resulting from the directional application then has pigments in an anisotropic arrangement. This means that the optical properties of the basecoat film and therewith the paint are dependent on the viewing angle. In practice, this may necessitate expensive measures for color matching of painted components, which, for example, directly abut each other as parts of a motor vehicle body (color matching).
- EP 1 423 299 B1 discloses a procedure which makes it possible to produce coatings with basecoat films which contain platelet-shaped dye and / or effect pigments, but whose optical properties are nevertheless independent of the viewing angle.
- a comparatively thick first basecoat partial layer is first applied to a substrate with the aid of a directed application method.
- This is covered in a subsequent step with a comparatively thin second basecoat partial layer, wherein the formation of the second base partial paint layer by means of a non-directional application method, for example by means of spraying. It has surprisingly been found that the overall optical effect of the multilayer basecoat layer produced in this way is dominated exclusively by the second basecoat film.
- a comparatively thin base coat partial layer with pigments in an isotropic arrangement on a comparatively thick base coat partial layer with pigments in an anisotropic arrangement causes the same optical impression as a single-coat base coat layer which has exclusively pigments in an isotropic arrangement.
- a disadvantage of this procedure is that the application of the basecoat film in several stages makes the coating process more expensive and the use of the non-directional coating method can lead to an uneven surface of the basecoat film.
- the present invention has for its object, basecoat films containing pigments and / or effect pigments, and to provide coatings with such basecoat films, without being confronted with the problems of the prior art.
- the invention proposes the coating with the features of claim 1 and the method with the features of claim 6. Further developments of the invention are the subject of dependent claims.
- the coating according to the invention is a multi-layered, applied to a substrate, color and / or effect paint. It is always characterized by a combination of the following features:
- the coating comprises a clearcoat film having a dry film thickness in the range from 10 ⁇ m to 50 ⁇ m, in particular from 25 ⁇ m to 40 ⁇ m, and
- the coating comprises a basecoat film having a dry film thickness in the range from 6 pm to 35 pm, in particular from 10 pm to 20 pm, into which colorants and / or effect pigments are incorporated whose orientation within the basecoat film influences the optical properties of the paint.
- the coating is characterized in that the base coat layer for controlling the Ori ent mich of the color and / or effect pigments contains so-called control particles, which control particles in turn by a dlO value of at least 50%, preferably of at least 60%, especially preferably at least 70%, the rock layer thickness of the basecoat layer and
- a d50 value in the range of 80% to 120% of the dry layer thickness of the basecoat layer, in particular in the range of 80% to 100% of the dry layer thickness of the basecoat layer, and
- dl00 value of not more than 200%, preferably of not more than 150%, in particular not more than 120%, of the rocking layer thickness of the basecoat film.
- the stated numerical values relate to the totality of all control particles contained in the basecoat film.
- the d50 value of the control particles (which subdivides the control particles contained in the basecoat into two equal partial fractions) is at least 80% and at most 120% of the dry layer thickness, at most 10% of the total control particles contained in the layer Having diameters less than 0.5 times, preferably 0.6 times, more preferably 0.7 times, the dry film thickness of the basecoat film, and the basecoat film is free of control particles having a diameter, which exceeds the dry layer thickness of the basecoat by more than 100%, preferably by more than 50%, especially before more than 20%.
- the diameters of the control particles are usually in the double-digit pm range.
- dlO, d50 and d100 values can be determined very reliably, in particular according to ISO 13320_2009 in conjunction with DIN ISO 9276-l_2004 (presentation of the results of particle size analyzes - Part 1: Graphical representation) and ISO 9276-2_2014 (Presentation of the results of particle size analyzes - Part 2: Calculation of mean particle sizes / diameters and moments from particle size distributions). Numerical data on the diameter of control particles are values determined using these standards.
- control particles defined in this way means that even when the basecoat film is applied by means of a directed application process, an isotropic arrangement of the dye and / or effect pigments can be achieved.
- the essential part of the control particles has a diameter which corresponds approximately to the T rocken Anlagendicke the base lacquer layer. This forces some of the color and / or effect pigments to be tangent to the surface of the control particles and thus at an angle, for example perpendicular, to the direction of the job.
- the control particle used can control the visual appearance of the basecoat film.
- the control particles exclusively control the angular dependence of the hue and no optical effects, such as color. the gloss of the paint.
- the dry layer thickness of the clearcoat layer and the basecoat layer in each case means the thickness of these layers after drying, ie if no solvent is contained in the layers. Dry layer thicknesses can be determined in particular according to DIN EN ISO 2808. In this case, numerical data for dry layer thicknesses are values determined by this standard. Particularly preferably, the clearcoat layer and the basecoat layer each have a substantially uniform T rocken harshdicke on. This is to be understood in particular that the average deviation of the dry layer thickness is preferably less than 10% of the value determined, for example, according to DIN EN ISO 2808.
- clearcoat film and the basecoat film of a erfindungsge MAESSEN paint although by definition are dried, but in no case must be cured already zwin quietly.
- the substrate can basically be any object, for example the motor vehicle body mentioned at the beginning or a piece of furniture.
- the substrate is particularly preferably a film, in particular a plastic film.
- a laminate of the carrier film and the coating layer (s) to be transferred is generally provided, in particular as a web material, for example with a web width of 600 mm and a web length of 700 m.
- the laminate is pressed with the paint layer or layers ahead on the workpiece to be painted.
- an adhesion-promoting layer can be applied beforehand to the lacquer side of the laminate and / or the workpiece to be lacquered.

- the control particles consist of a plastic that is thermally stable up to 140 ° C.
- control particles The material nature of the control particles is basically not important for the invention tion. On the other hand, what is important is the above-defined relative size of the control particles in relation to the core layer thickness of the basecoat film.
- control particles may consist of an acrylate such as polymethylmethacrylate.
- control particles even the basecoat layer in which they are embedded can give neither an angle-dependent hue nor an angle-dependent optical effect.

- the coating according to the invention is preferably characterized by at least one of the following features, particularly preferably by a combination of the following two features:
- the basecoat film contains the control particles in a proportion of from 2% by weight to 15% by weight (based on the solids content of the basecoat from which the basecoat film is formed, based on the basecoat film in the dried state).
- the basecoat film contains the color and / or effect pigments in a proportion of 0.15% by weight to 15% by weight (based on the basecoat film in the dried state, ie based on the solids content of the basecoat from which the basecoat film is formed becomes).
- the process according to the invention is used for the production of a basecoat film, particularly preferably for the production of the basecoat film of the above-described multilayer coating. Accordingly, the components necessary for the preparation of the basecoat film (basecoat, color and / or effect pigments, control particles) are also selected from those described above.
- the procedure always includes the following three steps:
- the basecoat always contains the color and / or effect pigments whose orientation within the basecoat affects their optical properties
- control particles for controlling the orientation of the dye and / or effect pigments in the base coat layer to be delivered.
- the basecoat contains a solvent in addition to the components mentioned.
- the solids content of the basecoat and / or the thickness of the basecoat film are adjusted such that the basecoat film is obtained with a dry film thickness in the range from 6 .mu.m to 35 .mu.m.
- the control particles used are those which have a d10 value of at least 50% of the dry film thickness of the basecoat film and a d50 value in the range of 80% to 120% of the dry film thickness of the basecoat material layer, in particular in the range of 80% to 100% of the dry layer thickness of the basecoat layer, and
- dl00 value of not more than 200%, preferably of not more than 150%, in particular not more than 120%, of the rocking layer thickness of the basecoat film.
- control particles used by no means necessarily have to have a mono-modal distribution. Rather, it may even be advantageous to use two or more STEU particulate fractions, each having a different d50 value, optionally also a different dlO and / or dl00 value.
- the d50 value of the entirety of the control particles in the basecoat film would then be 90% of the T rocker layer thickness of the basecoat film.
- the substrate is preferably one of the above-mentioned substrates.
- the substrate is a film to which a clearcoat has already been applied. In general, however, it is preferred if initially the basecoat film is applied to the film and then the clearcoat film.
- the application of the basecoat takes place with the aid of a directed application method.
- a directed application method in particular an order by means of casting, knife coating, rolling or Extrusionsbe layers in question.
- customary and known devices such as casting devices, doctor blades, rolls, in particular counter-rotating rolls, or extruders, in particular Folienex trudern.
- FIG. 1 schematically shows, in cross section, a basecoat film 101 applied to a substrate 100.
- the basecoat film 101 was applied by means of knife coating, ie by means of a directed order procedure.
- Platelet-shaped metal flakes 102 are embedded in the basecoat film 101 as color and / or effect pigments. These are all arranged in a preferred direction, namely in the direction of the job (arrow), as a result of the directed application method. Incident light is reflected by all metal flakes 102 similarly.
- the color and optical appearance of the basecoat film 101 is therefore strongly dependent on the angle.
- FIG. 2 shows schematically in cross section a basecoat film 201 applied to a substrate 200.
- the basecoat film 201 was formed by means of spray application, ie by means of a non-directional application process.
- Platelet-shaped metal flakes 202 are embedded in the basecoat film 201 as color and / or effect pigments. These are substantially more disordered than the metal flakes according to FIG. 1 as a result of the non-registered application method.
- Incident light is not uniformly reflected by all metal flakes 202.
- the color and optical appearance of the basecoat layer 201 is therefore significantly less dependent on the angle than in the case of FIG. 1.
- FIG. 3 shows schematically in cross-section a basecoat film 301 applied to a substrate 300.
- the basecoat film 301 was formed by means of knife coating, that is to say by means of a directed application process.
- the base lacquer layer 301 In the base lacquer layer 301 are plate-shaped metal flakes 302 embedded as a color and / or effect pigments. Despite the directed order procedure, these are not all arranged in a preferred direction, namely in the direction of the order. This is prevented by the ku gelförmigen control particles 303, which are like the metal flakes 302 embedded in the base coat layer 301.
- the control particle 303 has a diameter which corresponds approximately to the thickness of the basecoat film 301.
- a portion of the metal flakes 302 is forced to be parallel to the surface of the control particles 303 and thus to be skewed or even perpendicular to the direction of the job (arrow).
- the color and optical appearance of the basecoat film 301 is therefore significantly less dependent on the angle than in the case of FIG. 1.
- FIG. 4 is a detail from a photomicrograph of a section through a basecoat film 401 formed on a substrate 400 according to the invention by means of a directed application process, which is covered by a clearcoat film 404.
- the base coat layer 401 as metal and / or effect pigments metal flakes 402 and the control particles 403 are embedded.
- the control particle 403 has a diameter which corresponds approximately to the thickness of the base coat layer 401. It will be appreciated that the metal flakes 402 are forced into an oblique orientation by the control particle.
- a base paint having a solid content of 25% was applied by means of a doctor blade in a wet film thickness of 60 ⁇ m.
- the basecoat included a polyurethane-based binder, an additive mixture, and water as a dispersant.
- the mean diameter (d50) of the aluminum flakes was 10 ⁇ m.
- the particles of the organic color pigment consistently had sizes below 1 ⁇ m.
- a base paint having a solid content of 35% by means of a doctor blade was also applied in a wet film thickness of 60 ⁇ m.
- the basecoat had an identical composition to the basecoat used under A, with one exception: in addition to the aluminum flakes, it contained spheres of polymethylmethacrylate having an average diameter (d50) of 15 pm in a proportion of 1% by weight Weight refers to the basecoat in total, that is, including the dispersing agent and / or solvent). These serve in the sense of the present application as control particles.
