    Abstract: Compounds having isocyanate groups with or without blocking, allophanate groups and free-radically polymerizable C-C double bonds, the C-C double bonds being in activated form by virtue of a carbonyl group attached directly to them or by virtue of an oxygen atom in ether function (activated double bonds), derived from polyisocyanates and alcohols A which in addition to the alcohol group also carry an activated double bond (compounds I). The invention additionally relates to radiation-curable formulations and coating compositions comprising the compounds I, to methods for coating using these substances, and to coated articles produced using these methods. Furthermore, the invention relates to the use of the compounds I in radiation-curable compositions such as in casting compositions, dental compounds, composite materials, sealing compounds, adhesives, troweling compounds, printing inks, in photostructurable compositions such as solder resists, photoresists, photopolymeric printing plates, and stereolithography resins.

    Abstract: Arene bisphosphine oxides of the general formula in which the radicals R to R independently of one another stand for a hydrogen atom or a C1-C6-alkyl or alkoxy group, or a C5-C10-aryl group, a C5-C12-aryloxy group or a C7-C14-arylalkoxy group, R and R independently of one another stand for a C1-C6-alkyl group, a C5-C10-cycloalkyl group or a C5-C12 aryl group, which can also contain one or two nitrogen or sulphur atoms in the ring system or can carry one or two halogen atoms, C1-C6-alkyl groups or C1-C6-alkoxy groups as substituents on the ring system or can stand for a C1-C6-alkoxy group, a C3-C8-alkoxyalkoxy group, a C5-C12-aryloxy group or C7-C14-arylalkoxy group or R and R together form a bridge of 2 to 10 carbon atoms, it also being possible for some of the carbon atoms to be a constituent of an aromatic ring.

    Abstract: Radiation-curable urethane prepolymers are made from a mixture in which the isocyanate component contains two different trifunctional isocyanates or one tri- and one di-functional isocyanate, or the unsaturated polyol component contains at least two different unsaturated compounds with reactive hydroxyl groups and possibly other hydroxy compounds. A process for the production of radiation-curable, urethane group-containing prepolymers (PU) comprises reacting an isocyanate component (A) containing trifunctional isocyanate(s) (A1) and optionally difunctional isocyanate(s) (A2) with a polyol component (B) containing unsaturated compound(s) with at least one reactive hydroxyl group (B1) and optionally other OH group-containing compounds (B2), in which either (A) contains two different compounds (A1) or one (A1) and one (A2), or component (B) contains at least two different compounds (B1). Independent claims are also included for the following: (1) radiation-curable urethane prepolymers obtained by this process; (2) radiation-curable preparations containing prepolymers (PU) as above and possibly conventional additives etc.; (3) a process for coating substrates by applying PU or preparations containing PU to the substrate, removing any solvent; and hardening with UV or electron beam radiation; (4) coated substrates obtained by this process.

    Abstract: A mixture (I) contains (A) a condensation resin prepared from (A1) urea or urea derivatives and (A2) ketones or aldehydes consisting of C-H acidic aldehydes and/or ketones or mixed with formaldehyde and (B) a radiation curable compound containing 2-acryloyl- or methacryloyl groups. An Independent claim is included for a printing ink containing (I) as a binding agent.
