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

摘要

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.
