Abstract:
1. A composition capable of undergoing cationic polymerisation or radical polymerisation, and crosslinking by irradiation, or by beams of electrons, comprising: (A) at least one polymerisable organic matrix or at least one partially polymerised organic matrix, comprising monomers, comonomers, oligomers, cooligomers, polymers, or copolymers having epoxy functions (frA); (B) at least one silicone diluent with a viscosity ηr at 25° C. of less than or equal to 200 mPa·s, and comprising: at least one unit of formula (I): wherein: a=0, 1 or 2, R at least two silicon atoms; and (C) an effective amount of at least one cationic or radical photoinitiator which is an onium borate of an element from groups 15 to 17 of the Periodic Table or of an organometallic complex of an element from groups 4 to 10 of the Periodic Table, and wherein the onium is the sulphonium salt of 2-ethyl-4-oxoisothiochromanium or of 2-dodecyl-4-oxoisothiochromanium.
