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.

A photoinitiator composition is described that includes a specific iodonium salt combined with a hydrogen donor that is a Guerbet alcohol that can also act as a solvent. This initiator system can solve problems concerning odor, in particular after the polymerization/cross-linking of conventional iodonium salts.

A photo-primer composition B is described that includes a specific iodonium salt combined with a hydrogen donor that is a Guerbet alcohol that can also be used as a solvent. The primer system can be used for solving odor problems, particularly after the polymerization/cross-linking of traditional iodonium salts.
