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:
The present invention relates to a process for preparing nondispersing (meth)acrylic esters containing urethane groups, comprising a) reacting at least one hydroxyl-containing compound with (meth)acrylic acid in a solvent, to form an ester; b) removing the solvent and optionally a part of unreacted (meth) acrylic acid; c) reacting the mixture resulting from stage a) or b) with at least one epoxy-functional compound in an amount corresponding to the acid number of the mixture; and d) reacting the mixture resulting from stage c) with at least one compound containing isocyanate groups, and such esters obtainable in this way, and radiation-curable coating compositions comprising said esters, and a process for preparing these coating compositions.
