Problems solved by technology

[0026] It was actually found that iodine Photoinitiators of the borate type, although they are particularly effective, have the main drawback that they are formulated in silicone compositions using alcoholic solutions (usually methanol or isopropanol solutions), which have flash interactions with these solvents. security issues
In addition, there is a possibility that the presence of a characteristic odor due to the decomposition of the photoinitiator after its use leads to an unpleasant feeling for the user

Embodiment

[0276] 1) Synthetic photoinitiator [(C 12 H 25 )-Ph-I-Ph(C 12 H 25 )] + ； - B[C 6 F 5 ] 4 and can be prepared Composition used as cationic photoinitiator of the present invention

[0277] A 1 liter round bottom flask equipped with mechanical stirring, water condenser and dropping funnel was charged with dodecylbenzene (100 g; 0.45 mol), potassium iodide (43.5 g; 0.203 mol), acetic acid (199.6 g) and ethyl Anhydride (59.5 g). The mixture was stirred and cooled at 0 °C in an ice bath. A mixture of sulfuric acid (59.8 g) and acetic acid (39.86 g) was charged to the dropping funnel. This mixture was added to the reaction mass within 25 minutes. The mixture was then returned to ambient temperature (20°C) and then stirred at ambient temperature for 18 hours. Water (750ml) was then added and the reaction mass was extracted with three portions of ether (3 x 350ml). The ether phases were combined and then evaporated under reduced pressure....

Abstract

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.

Description

technical field [0001] The field of the invention is that of compositions useful as cationic photoinitiators in compositions based on monomers, oligomers and / or polymers, which The compositions are capable of polymerizing or crosslinking by cationic routes and comprise reactive functional groups to obtain polymerized and / or crosslinked films, coatings or massique materials (eg composites). [0002] More specifically, the object of the present invention is to: [0003] - new compositions useful as cationic photoinitiators, new processes for the preparation of these compositions and their use as photoinitiators for polymerizing or crosslinking monomers and prepolymers by cationic routes, [0004] - a cationic polymerizable or crosslinkable composition comprising a photoinitiator according to the invention and an organosilicon-containing reactive compound, by electron beams or under thermal, photochemical activation, by cationic routes, [0005] - a method for producing a film ...
