Solids containing (i) on average per molecule at least two groups (a) having at least one bond which can be activated with actinic radiation whereby the groups (a) are structurally different from one another and are attached to the parent structure of the solid via urethane groups, or containing (ii) on average per molecule more than one group (a) having at least one bond which can be activated with actinic radiation, the groups being structurally different from one another or the same and being attached to the parent structure of the solid via urethane groups, and from 0.01 to 1 mol %, based on the bonds present which can be activated with actinic radiation, of at least one chemically bonded polymerization inhibitor (b), preparable by reacting the starting products in the melt; use of the solids as coating materials, adhesives or sealing compounds or for preparing them; coating materials, adhesives or sealing compounds preparable using the solids; and coatings, adhesive films or seals producible from the coating materials, adhesives or sealing compounds.

Solid containing groups which are bound to the base structure via ureathane groups and which contain bonds that can be activated by actinic radiation, and the use thereof

Multi-layer paints and method for producing the same

Compounds having isocyanate groups with or without blocking, allophanate groups and free-radically polymerizable C&mdash;C double bonds, the C&mdash;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.

Coating agents which can be hardened by the addition of isocyanate groups as well as by the radiation-induced addition of activated c-c double covalent bonds

Utilization of phenylglyoxalic acid esters as photoinitiators

The present invention relates to an aqueous dispersion comprising a solid pulverulent component A and an aqueous component B, said component A comprising a UV-curable powder coating material.

Aqueous dispersion of transparent powder coating material

Compounds having alcoholic hydroxyl groups are esterified with acrylic or methacrylic acid in the presence of copper(II) salts or mixtures thereof as polymerization inhibitors and in the presence of a hydrocarbon as a water-entraining agent with removal of the water of reaction at from 90 to 150&deg; C. After the esterification, the copper salt is precipitated as copper sulfide and is separated off from the ester. The light-color (meth)acrylates resulting in the high yields are particularly suitable for coatings containing colored pigment on substrates such as wood, paper, mineral building materials, plastics or metal.
