Publication number: 20070172595Abstract: Disclosed herein are processes for producing a multilayer sheet as well as uses thereof. 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.Type: ApplicationFiled: March 2, 2005Publication date: July 26, 2007Applicant: BASF COATINGS AKTIENGESELLSCHAFTInventors: Bernd Biallas, Wolfgang Duschek, Klaus-Dieter Stegemann, Markus Saedler
