Optical device with antistatic property

An optical device comprising a first optical member having a front surface, a second optical member, and an antistatic layer disposed between the first optical member and the second optical member wherein the first optical member, the second optical member, and the antistatic layer define an optical path such that light incident to the front surface of the first optical member will pass through each of the first optical member, the second optical member, and the antistatic layer;

• wherein the antistatic layer is transparent and has a glass transition temperature of 20° C. or less and is the reaction product of a reaction mixture consisting essentially of photo-initiator, 2 to 90 wt. % of at least one polymerizable onium salt having a fluoroorganic anion, at least one non-onium polymerizable multifunctional (meth)acrylate monomer or oligomer and optionally at least one polymerizable monofunctional (meth)acrylate monomer or oligomer, wherein the onium salt has the formula:
• (R1)a-bG+[(CH2)qDR2]bX−
• wherein:
• each R1 comprises independently an alkyl, alicyclic, aryl, alkalicyclic, alkaryl, alicyclicalkyl, aralicyclic, or alicyclicaryl moiety, wherein such moiety may comprise one or more heteroatoms such as for example, nitrogen, oxygen, or sulfur, or may comprise phosphorus, or a halogen;
• R1 may be cyclic or aromatic and include G+in the cycle;
• G is nitrogen, sulfur, or phosphorus;
• a is 3 where G is sulfur and a is 4 where G is nitrogen or phosphorous;
• b is an integer of 1 to 3 where G is sulfur and b is an integer of 1 to 4 where G is nitrogen or phosphorus;
• q is an integer from 1 to 4;
• D is oxygen, sulfur, or NR wherein R is H or a lower alkyl of 1 to 4 carbon atoms;
• R2 is a (meth)acryl;
• and
• X−is a fluoroorganic anion which is a methide or an imide.
