Abstract: Described is a method for producing a multicoat color and/or effect paint system. A pigmented aqueous basecoat material is used which comprises at least one phosphite of the formula (I): wherein at least one of the radicals R1 to R3 is selected from the group of aliphatic hydrocarbons. The sum total of the weight percentage fractions of all of the phosphites of structural formula (I) here is 0.1% to 5% by weight, based on the total weight of the basecoat material used. Moreover, described are the corresponding basecoat materials, the corresponding multicoat color and/or effect paint system, and the use of the phosphites in pigmented aqueous coating materials. Also described is a method for repairing defects on multicoat color and/or effect paint systems produced with the aid of the above-identified method of the invention.

Abstract: Described is a method for producing a multicoat color and/or effect paint system by (1) applying to a substrate a pigmented aqueous basecoat material, (2) forming a polymer film from the coating material applied in stage (1), (3) applying a clearcoat material to the resultant polymer film, and then (4) curing the polymer film together with the clearcoat film. The pigmented aqueous basecoat material comprises at least one alcohol having a structure: wherein R is a C1 to C4 alkyl radical, with the proviso that R is not an n-butyl radical. The at least one alcohol is used in an amount of 0.1% to 5% by weight, based on the total weight of the aqueous basecoat material. Additionally, described are the corresponding coating materials and also the use of the alcohols in pigmented aqueous coating materials.
