Abstract: The use of radiation-curable preparations contains polymer(s) P1 with ethylenic double bonds for coating moulded products containing mineral binders (mineral mouldings). Also claimed is (i) a process for the production of coated mineral mouldings by applying this type of preparation to the surface of a moulded product, possibly removing any solvent, and hardening with UV or electron beam radiation; (ii) coated mineral mouldings obtained by this process.

Abstract: UV- and heat-curable aqueous polyurethane dispersions comprise compounds attached via polyisocyanates and containing UV-polymerizable C=C double bonds, aliphatic diols incorporated by way of isocyanates and having a molecular weight of less than 500 g/mol, compounds attached via isocyanates and containing carboxylic acid or sulfonic acid groups and/or salts thereof, free hydroxyl groups, and compounds containing blocked isocyanate groups. They are suitable for coating heat-stable substrates such as metal substrates and may be used with advantage for automotive clearcoats.

Abstract: Cholesteric material is produced by applying a pourable cholesteric mixture to a support and forming a solid layer. Cholesteric material comprises a cholesteric layer(s) of average thickness below 0.2 mu . Independent claims are included for the production of the material by applying a pourable cholesteric mixture to a support and forming a solid layer, a pigment obtained by grinding the material and a composition containing the pigment.
