Abstract:
1. Process for producing two-tone coated substrates, consisting of the successive steps: a) providing a non-color-imparting pre-coated substrate, wherein said substrate is precoated with an electrodeposition primer, b) directly applying a color-imparting coating of Color 1 over at least one or more regions of the pre-coated substrate side facing an external observer, c) curing the coating of Color 1, d) masking the desired region of the coating of Color 1, e) applying a color-imparting coating of Color 2 to the unmasked regions of the substrate side facing the external observer without deliberately curing the coating of Color 2, f) unmasking the regions masked in step d), g) applying a clear coat to the whole of the substrate side facing the external observer and h) curing the clear coat wherein the color-imparting coating of Color 1 applied in step b) is applied from a coating composition selected from the group consisting of a modified solid-colored base coat and said modified solid-colored base coat applied first of all and an unmodified solid-colored base coat applied subsequently and the color-imparting coating of Color 2 applied in step e) is applied from a coating composition selected from the group consisting of a modified special effect base coat and said modified special effect base coat applied first of all and an unmodified special effect base coat applied subsequently, wherein the modified solid-colored base coats used in steps b) and wherein the modified special effect base coat e) are in each case produced by mixing of an unmodified solid-colored base coat with an admixture component and an unmodified special effect base coat with said admixture component, wherein the admixture component is selected from the group consisting of polyisocyanate crosslinking agents, polyurethane resins and filler pastes.
