CHROMOPHORIC OR EFFECT-GENERATING MULTILAYER PAINT COATINGS HAVING PIGMENT-FREE COATS OF PAINT AS FILLER SUBSTITUTE, THE PRODUCTION THEREOF AND USE THEREOF
Multicoat color and/or effect finishes on substrates, comprising, lying atop one another in this order: (A) at least one pigment-free coating, (B) at least one color and/or effect coating, and (C) at least one transparent coating, processes for producing them, and their use.
1 . A multicoat color and/or effect finish on a substrate, comprising:
(A) at least one pigment-free coating,
(B) at least one color and/or effect coating lying atop the at least one pigment-free coating (A), and
(C) at least one transparent coating lying atop the at least one color and/or effect coating (B).
2 . The multicoat finish of claim 1 , wherein coating (A) is produced from a transparent coating material (A′) curable thermally and/or with actinic radiation.
3 . The multicoat finish of claim 2 , wherein the coating material (A′) is a clearco at material.
4 . The multicoat finish of claim 2 , wherein the coating material (A′) is an aqueous coating material.
5 . The multicoat finish of claim 1 , wherein coating (B) is produced from a transparent coating material (B′) curable thermally and/or with actinic radiation.
6 . The multicoat finish of claim 5 , wherein the coating material (B′) is a basecoat material.
7 . The multicoat finish in claim 5 , wherein the coating material (B′) is an aqueous coating material.
8 . The multicoat finish of claim 5 , wherein the coating material (B′) comprises a color and/or effect pigment.
9 . The multicoat finish of claim 5 , wherein the coating material (B′) comprises a functional pigment.
10 . The multicoat of claim 1 , wherein coating (C) is produced from a transparent coating material (C′) curable thermally and/or with actinic radiation.
11 . The multicoat finish of claim 1 , wherein the substrate comprises at least one material selected from the group consisting of metals, plastics, glass, wood, leather, textile, ceramic or natural stone.
12 . A process for producing the multicoat color and/or effect finish of claim 1 comprising,
applying to a substrate at least one coating material (A′) to produce a wet film of the coating material (A′);
subsequently applying at least one coating material (B′) to the wet film of the coating material (A′) to produce a wet film of the coating material (B′),
subsequently applying at least one further coating material (C′) to the wet film of the coating material (B′) to produce a wet film of the coating material (C′),
wherein the substrate is at least one of
(i) an unprimed substrate,
(ii) a substrate coated with at least one uncured or only partially cured primer (G) and
(iii) a substrate coated with at least one fully cured primer (G) and
jointly curing of
(1) the resulting wet films of the coating materials (A′), (B′), and (C′) or
(2) the resulting wet films of the coating materials (A′), (B′), and (C′) and the uncured or only partially cured primer or primers (G).
13 . The process of claim 12 , wherein the coating materials (A′), (B′), and (C′) are applied by means of pneumatic spray application or by electrostatic spray application (ESTA).
14 . A substrate coated with the multicoat finish claim 1 .
15 . The process of claim 13 , wherein the coating materials (A′), (B′), and (C′) are applied with high speed rotary bells.
