Abstract
Optical devices comprising at least one optical layer and at least one antistatic layer disposed on at least one surface of the optical layer wherein the antistatic layer comprises the reaction product of: (a) at least one polymerizable onium salt; and (b) at least one polymerizable, non-onium, silicone or perfluoropolyether moiety-containing monomer, oligomer, or polymer.
Claims8
An optical device comprising at least one optical layer and at least one antistatic layer disposed on at least one surface of said optical layer wherein said antistatic layer comprises the reaction product of a reaction mixture comprising:
- (a) 30 to 50 weight percent of at least one polymerizable ionic liquid onium salt which is a (meth)acryl functional quaternary ammonium salt having a melting point (Tm) below 100° C. and comprising an anion selected from the group consisting of alkyl sulfates, methane sulfonates, tosylates, —C(SO2CF3)3, —O3SCF3, —O3SC4F9, and —N(SO2CF3)2;
- and
- (b) at least one non-onium acrylate functional silicone polyether.
An optical device comprising at least one optical layer and at least one antistatic layer disposed on at least one surface of said optical layer wherein said antistatic layer comprises the reaction product of a reaction mixture comprising:
- (a) 9.9 to 98 weight percent of at least one polymerizable ionic liquid onium salt which is a (meth)acryl functional quaternary ammonium salt having a melting point (Tm) below 100° C. and comprising an anion selected from the group consisting of alkyl sulfates, methane sulfonates, tosylates, —C(SO2CF3)3, —O3SCF3, —O3SC4F9, and —N(SO2CF3)2;
- and
- (b) at least one non-onium acrylate functional silicone polyether;
- wherein said optical layer is selected from the group consisting of reflective polarizers, brightness enhancement films, and diffuse reflecting polarizing films.
