Title:

A manufacturing method of the double layer paint which gives a color and/or an effect

Document Type and Number:

Japanese Patent JP5968434

Kind Code:

B2

Abstract:

Disclosed is a method for producing a multicoat color and/or effect paint system, comprising (1) applying a pigmented aqueous basecoat to a substrate, (2) forming a polymer film from the basecoat applied in stage (1), (3) applying a clearcoat to the polymer film, and then (4) curing the polymer film together with the applied clearcoat to form a clearcoat film. The pigmented aqueous basecoat comprises at least one ester characterized by the following structure: where R1 is selected from the group of ethyl and isopropyl and R2 is a C2 to C8 radical. The at least one ester is used here in an amount of 0.1% to 5% by weight, based on the total weight of the aqueous basecoat applied in stage (1). The invention further provides the corresponding coating materials and the use of the esters in pigmented aqueous coating materials.
