Abstract: The invention relates to aqueous polyurethane dispersions which can be hardened with UV radiation and thermally. Said polyurethane dispersions contain the following: compounds bonded with polyisocyanates, with C=C doubl e bonds that can be polymerised with UV-radiation; aliphatic diols inserted wi th isocyanates, with a molecular weight of less than 500 g/mol; compounds bonde d with isocyanates, with carboxylic acid or sulphonic acid groups and/or salts thereof, free hydroxyl groups and compounds with blocked isocyanate groups. The inventive polyurethane dispersions are suitable for coating thermostable substrates such as metal substrates and can be advantageously used for clear automobile lacquers.

Abstract: The invention relates to compounds comprising isocyanate groups or capped isocyanate groups, allophanate groups and radically polymerizable C-C double covalent bonds, whereby the C-C double covalent bonds are activated by a carbonyl group bonded directly thereon or by an O-atom in ether function (activated double covalent bonds), derived from polyisocyanates and alcohols A which, in addition to the alcohol group, carry another activated double covalent bond (compounds (I)). The invention also relates to radiation- hardenable preparations and coating agents which contain compounds (I), to methods for coating while using these substances, and to coated articles produced according to these methods. The invention additionally relates to t he use of compounds (I) in radiation-hardenable materials such as in casting materials, dental materials, composite materials, sealants, adhesives, fillers, printing inks, in photostructurable materials such as solder resist s, photoresists, photopolymeric printing plates, and stereolithographic resins.

Abstract: Determination of the effectiveness of an irradiation wavelength(s) in a light-driven reaction(s) in at least one position of a probe comprises irradiating the probe with light and evaluating the condition of the probe. Determination of the effectiveness of an irradiation wavelength(s) in a light-driven reaction(s) in at least one position of a probe comprises irradiating the probe with light and evaluating the condition of the probe. Independent claims are also included for two evaluation apparatus, both comprising a light source with variable wavelength and a focussing apparatus, one further including an apparatus for irradiating monochromatic light and detecting the resulting scattered light and the other an apparatus for focussing irradiated light on or in the probe along the axis and detecting the scattered light.
