| 20110118374 | Method for Preparing a Hard Film or Coating from a Cationically Cross-Linkable/Polymerizable Composition Comprising an Iodonium Borate and Giving Off an Acceptable Odour - The invention relates to a method for preparing a hard film or coating from a composition based on monomers, oligomers and/or polymers capable of being involved in cationic polymerization and/or crosslinking reactions, comprising reactive functional radicals capable of forming intra-chain and inter-chain bridges, so as to obtain a polymerized and/or crosslinked film, coating or bulk (for example composite) material which has a certain level of hardness and a certain level of mechanical strength. The initiator system for polymerization and/or crosslinking, formed by an iodonium borate photoinitiator and by a photosensitizer chosen from di-anthracene-ethers, di-naphthalene-ethers and/or di-benzene-ethers, makes it possible to use a smaller amount of iodonium borate compared with the known systems, for an equivalent efficiency and with an acceptable odour being given off, in particular after polymerization/crosslinking. | 05-19-2011 |
