The present invention provides a magnetic multilayer pigment flake and a magnetic coating composition that are relatively safe for human health and the environment. The pigment flake includes one or more magnetic layers of a magnetic alloy and one or more dielectric layers of a dielectric material. The magnetic alloy is an iron-chromium alloy or an iron-chromium-aluminum alloy, having a substantially nickel-free composition. The coating composition includes a plurality of the pigment flakes disposed in a binder medium.

Disclosed herein is an additive for a paint or stain composition or for a colorant composition. The additive is polymerized from at least one acrylate monomer and a chain transfer agent. The additive has a weight molecular weight from about 2,000 Daltons to about 5,000 Daltons, and the chain transfer agent comprises a hydrogen-sulfur functionality. The additive's glass transition temperature ranges from about −50° C. to about −10° C. and the additive is hydrophobic.

A liquid or pasty pigment and/or filler preparation comprising: 1 to 70% by weight of at least one pigment dispersed in the preparation and/or at least one filler dispersed in the preparation (component (A)), 1 to 25% by weight of at least one inorganic, particulate component dispersed in the preparation, as component (B), 0 to 10% by weight of at least one surface-active wetting agent, which preferably also has dispersing properties, and as the remainder water and/or at least one solvent, the particles of component (B) being nanoscale or microscale and being inorganically or organically surface-modified, the surface modifier used being selected such that component (B) has a cationic, anionic, amphoteric or non-ionic surface, and component (B) further has a zeta potential which is opposite to the charge of the particles of component (A) or, in the case of uncharged particles of component (A), has a zeta potential in the range of −60 to +40 mV so as to effect adhesion of the particles (B) to the pigment and/or filler surface. The liquid pigment and/or filler preparations are excellently suited for the production of a wide variety of varnishes and paints for various applications, but also for the colouration of plastics, for example.

A pasty composition for the manufacture of three-dimensional structures or structural elements on the surface of a substrate is formed together with a polymer as an organic component B1, and a powdery material that makes up a proportion of solid in the range of 60 mass % to 95 mass % in the composition, and at least two mutually different solvents C1 and C2 that form a solvent mixture. A first solvent C1 has a boiling temperature here that is lower than the boiling temperature of the further solvent or solvents C2.

Disclosed herein is an additive for a paint or stain composition or for a colorant composition. The additive is polymerized from at least one acrylate monomer and a chain transfer agent. The additive has a weight molecular weight from about 2,000 Daltons to about 5,000 Daltons, and the chain transfer agent comprises a hydrogen-sulfur functionality and is present from about 8 to about 20 parts per hundred parts of monomers. The additive's glass transition temperature ranges from about −50° C. to about −10° C. and the additive is hydrophobic. The additive is added to the colorant composition to minimize tip drying at the colorant canisters, and is added to paint or stain composition as an open time extender.
