Abstract: Disclosed herein is a multilayer coating including at least one ground coat layer, the at least one ground coat layer including at least one non-platelet-shaped titanium dioxide pigment (T); at least one midcoat layer on top of the at least one ground coat layer, and at least one clearcoat layer on top of the at least one midcoat layer; and having a lightness L* according to CIELab in the viewing angle range from −15° to +45° of at least 80; in the viewing angle range from +75° to +110° of at least 70, if a metal effect pigment is contained in the midcoat layer; in the viewing angle range from +75° to +110° of at least 75, if no metal effect pigment is contained in the midcoat layer. Further disclosed herein are a method for producing such multilayer coating and a multilayer coated substrate.

Abstract: Disclosed herein are a method for producing materials having at least one carbamate functionality, carbamate-functional materials obtained from the process, coating compositions including said carbamate-functional materials, and a process for at least partially coating a substrate with the coating compositions. The method disclosed herein reduces unwanted transesterification which can occur as a side reaction by using a tertiary alkyl carbamate in combination with a tin catalyst and thus results in increased yields and purity of the carbamate-functional materials.
