- a base coat layer is produced on a substrate surface using a paint containing at least one platelet-shaped pigment
- the basecoat is overcoated with a transparent lacquer
- lacquers containing aluminum plates are used as lacquers containing platelet-shaped pigments for the production of the base lacquer layer, then the widespread metallic effect lacquers are obtained, for example.
- Both the basecoat layer can be touched up with a transparent lacquer or the baked multi-layer lacquer coating with a lacquer containing at least one pigment in the form of a plate, in the latter case Case is overpainted again with a transparent lacquer and then baked again. It is very important that the repaired areas on the finished paintwork are not recognizable by differences in color and brightness.
- At least the last spraying step for the production of the basecoat film is carried out with the aid of a pneumatic application process in the case of automotive serial painting.
- Pneumatic application methods are, however, disadvantageously characterized in that a relatively large part of the sprayed amount of paint does not reach the substrate, with the result that the circulating air in the spray booth must have high speeds so that the relatively large amounts of overspray are separated and disposed of can be.
- the technical object on which the present invention is based is to provide a method for producing and repairing multi-layer effect coatings, in which
- a base lacquer layer is produced on a substrate surface using a lacquer containing at least one platelet-shaped pigment
- this base lacquer layer is optionally repaired by spraying on a lacquer containing at least one platelet-shaped pigment
- the burned-in multilayer coating is optionally repaired by spraying on a coating containing at least one platelet-shaped pigment

- the basecoat film is produced, preferably in only one spraying step, exclusively by electrostatic spraying.
- electrostatic spraying the amount of the sprayed coating material which reaches the substrate is considerably larger than in the case of pneumatic application processes. The consequence of this is that the speed of the circulating air in the spray booth can be reduced and that smaller amounts of paint overspray have to be worked up and disposed of.
- the painting installation required for the production of multilayer effect paints can be considerably reduced if the basecoat film can be produced in just one spray pass.
- step (1) of the process according to the invention all of the platelet-shaped pigments containing platelet-shaped pigments suitable for the serial painting of automobile bodies can be used, provided they have a solids content of 18% by weight and a temperature of 23 ° C. at a shear rate of 1,000 s _1 after a shear time of 6 s an apparent viscosity of 40 to 200, preferably 60 to 150 mPa s, after a shear time of 300 s at a shear rate of 1000 s " 1 an apparent viscosity of 40 to 200, preferably 60 to 150 mPa s, at a shear rate of 5 s _1 after an shear time of 10 s an apparent viscosity of 100 to 2000, preferably 200 to 800 mPa s and after a shear time of 300 s at a shear rate of 5 s " 1 has an apparent viscosity of 100 to 2000, preferably 500 to 1500 mPa s, the measurements carried out at the shear rate of
- rheology aids such as, for example, crosslinked polymer microparticles (cf. for example EP-A-38127), finely divided silica, anionic polyacrylate resins, layered silicates, etc.
- the person skilled in the art can, in principle, use any of the series ⁇ painting suitable basecoat on a viscosity hold that meets the above conditions.
- the basecoats used in stage (1) of the process according to the invention can be either aqueous or non-aqueous.
- platelet-shaped pigments in particular aluminum pigments and / or pearlescent pigments containing basecoats suitable for the serial painting of automobiles, have been known for a long time and are commercially available in a large number of different embodiments, a detailed description is not necessary here.
- Aqueous basecoats are described, for example, in EP-A-38127 and non-aqueous basecoats are described, for example, in US-A-4,220,679.
- the process according to the invention is particularly well suited for the production and repair of multi-layer effect coatings with darker shades (e.g. diamond black) and for the production and repair of multi-layer effect coatings with lighter shades (e.g. silver).
- darker shades e.g. diamond black
- lighter shades e.g. silver
- the basecoat layer produced in stage (1) is produced exclusively by electrostatic spraying.
- electrostatic spraying the amount of the sprayed coating material which reaches the substrate is considerably larger than in the case of pneumatic application processes. The consequence of this is that the speed of the circulating air in the spray booth can be reduced and that smaller amounts of paint overspray have to be worked up and disposed of.
- the painting installation required for the production of multi-layer effect lacquers can be considerably reduced if the base lacquer layer is produced exclusively by electrostatic spraying.
- the application of basecoats containing platelet-shaped pigments electrostatic spraying is well known to the person skilled in the art and therefore does not need to be explained in more detail here
- stage (2) or stage (5) is carried out with the aid of a spray application method in which a spray jet consisting of paint drops is produced, which is characterized in that

- Spray application processes in which the paint drops in the spray jet correspond to the abovementioned conditions can be carried out, for example, using HVLP (high volume, low pressure) spray guns which are commercially available.
- the diameter, the speed and thus also the momentum of the paint drops in the spray jet essentially depend on the paint outflow rate, the atomizing air quantity or atomizing air pressure, the paint viscosity and the nozzle geometry.
- a reduction in the paint outflow rate results, for example, in a reduction in the paint drop diameter and in an increase in the speed of the paint drop.
- An increase in the atomizing air pressure also leads to a reduction in the paint drop diameter and to an increase in the speed of the paint drop.
