Abstract: Disclosed herein is a multilayer coating system present on a substrate and including at least two coating layers L1 and L2 different from one another, namely a first coating layer L1 applied over at least a portion of the substrate, and a second topcoat layer L2 applied over the first coating layer L1, where the topcoat layer L2 is formed from a coating composition including at least one block copolymer containing a backbone and at least two blocks B1 and B2 and side chains S1 and S2 including different polymeric moieties M1 and M2. Also disclosed herein are a method of preparing said multilayer coating system, a coated substrate obtainable therefrom, and a method of using a coating composition including the block copolymer for improving, in particular for increasing, the chromaticity of the multilayer coating system.

Abstract: Disclosed herein is a multilayer coating system present on a substrate and including at least three coating layers L1, L2 and L3 different from one another, namely a first pigmented coating layer L1 applied over at least a portion of the substrate, a second coating layer L2 applied over the first pigmented coating layer L1, and a third coating layer L3 applied over the second coating layer L2, where the second coating layer L2 is formed from a coating composition including at least one block copolymer containing a backbone and at least two blocks B1 and B2 and side chains S1 and S2 including different polymeric moieties M1 and M2. Also disclosed herein are a method of preparing said multilayer coating system, a coated substrate obtainable therefrom, and a method of using a coating composition including the block copolymer for improving the chromaticity of the multilayer coating system.

Abstract: Disclosed herein is a method of preparing a multilayer coating system on a substrate including a step of applying at least one organic black pigment containing basecoat composition to a substrate and forming a first coating film thereon (1), optionally subsequently applying a second basecoat composition and forming a second coating film adjacent to the first coating film (2), and applying a pigmented topcoat composition to the first coating film in case optional step (2) is not performed (3a), or applying a clearcoat composition to the second coating film in case optional step (2) is performed, and where steps (1), (2) and (3b) are performed, or steps (1) and (3a) are performed, includes at least one non-black coloring pigment having a volume average particle size of <1000 nm in an amount in the range of from 0.01 to 7.50 wt.-%, based on its total solid content.

Abstract: Pharmaceutical complexes composed of drug molecules entrapped in cyclodextrin-based MOFs (CD-MOFs) are provided. Pharmaceutical tablets incorporating crystals of the pharmaceutical complexes for oral administration to a patient are also provided. In addition, methods of making the pharmaceutical complexes using anion-exchange reactions and methods of making the pharmaceutical complexes based on the co-crystallization of the drug molecules with cyclodextrin are provided. The pharmaceutical complexes include a CD-MOF and deprotonated drug anions associated with alkali metal cations in the CD-MOF superstructure.
