摘要： The present invention concerns type II photoinitiators for the free-radical crosslinking of silicone compositions, in particular acrylic silicone compositions. The present invention concerns a silicone composition C1 that can be crosslinked by exposure to radiation with a wavelength of between 300 and 450 nm, comprising: —at least one organopolysiloxane A comprising at least one methacrylate group bonded to a silicon atom, at least one organohydrogenopolysiloxane H comprising at least two, and preferably at least three hydrogen atoms each bonded to different silicon atoms, and—at least one free-radical photoinitiator P. The present invention also concerns the provision of a silicone composition that can be polymerized or crosslinked by free-radical process comprising a type II photoinitiator system suitable for crosslinking silicone compositions, in particular by exposure to radiation, and absorbing light radiation with a wavelength greater than 300 nm.

摘要： In a first aspect, the present invention concerns a kit for a polymerizable composition comprising a portion A constituted by a composition comprising at least one monomer (a1) that is reactive towards a cationic species (b) or a Lewis or Brönsted acid species, and at least one co-initiator, and a portion B comprising at least one cationic salt (e) selected from the salts with formula S1, S3, and S4 shown and defined in claim 1. In a second aspect, the present invention concerns a method of producing a coating or a composite material starting from polymerizable composition comprising at least one salt (e) selected from the salts with formula S1, S2, S3, and S4 shown and defined in claim 10, said composition being polymerized without adding external heat thereto.
