Technical Field

The present invention relates to an organopolysiloxane compound, a method for producing the same, and an antistatic agent and a curable composition containing the same, and more particularly, to an organopolysiloxane compound having an organopolysiloxane structure and a polymerizable reactive group and an ionic group in a molecule, a method for producing the same, and an antistatic agent and a curable composition containing the organopolysiloxane compound.

Background

An onium salt in which the cation is ammonium or phosphonium having a trialkoxysilylalkyl group and the anion is perfluoroalkylsulfonylimide has been reported to be useful as a low-molecular antistatic agent for a fluororesin (see patent document 1).

However, the present inventors have found that 1 type of 1- (3-trimethoxysilylpropyl) -1, 1, 1-tributylphosphonium ═ bis (trifluoromethanesulfonyl) imide, which is the onium salt, is used as an antistatic agent for an electron beam-curable acrylic resin, and as a result, it has not been possible to impart practical antistatic properties.

Patent document 2 discloses a silicone copolymer obtained by copolymerizing an onium salt having an alkoxysilyl group and a dialkoxysilane as a compound capable of improving the antistatic performance.

However, the present inventors have found that the above silicone copolymer is excellent in initial antistatic performance, but has insufficient durability, particularly water resistance, because it does not have a polymerizable reactive group reactive with an electron beam-curable acrylic resin in the molecule, and the antistatic performance is lowered with time by contact with water.
