In one embodiment, a process for producing a multilayer sheet S by coating a carrier sheet with a pigmented basecoat film, if desired, a second pigmented basecoat film, and a clearcoat. The process comprises: applying a pigmented basecoat material to the carrier sheet and adjusting the film la to a residual volatiles content “x” less than 10% by weight, to give a film 1b. A surface of the film 1b is adjusted to a temperature of <50° C. If desired, a second pigmented basecoat material or the pigmented basecoat material is applied to the film 1b to give a film 2a, and adjusting the film 2a to a residual volatiles content “y” of <10% by weight, based on the basecoat film. If appropriate, the films 1b and 2b are adjusted to a temperature of <50° C. at a surface of the film 2b.

Abstract: A method of determining direction-dependent properties of coatings, in which measurements of coating properties are made along a test track (4a, 4b) on a sample coating using one or more measuring instruments and at least one measurement is recorded in relation to direction (6).

Abstract: In a method of determining the shade stability of paints, the total color difference &Dgr;E(FT) between the color at the film thickness FT and the color at a predetermined film thickness FT0 is measured for different film thicknesses FT. Subsequently, the slope &sgr;(FT) of the plot &Dgr;E(FT) is determined, which represents a useful parameter for the shade stability. Alternatively to &sgr;(FT), it is also possible to determine the limiting film thickness FTlim at which the total color difference &Dgr;E(FT) passes below a predetermined limit. The method of determining the shade stability is additionally employed in order to optimize paint formulations.

In the measuring station (9) measurement of the various properties of the coating is carried out by the laboratory robot (3) using various measuring devices (4). This process can in particular involve spatial resolution and electronic recording. The test panels can furthermore be distinguished by a bar code system which is recorded and evaluated electronically.
