<p>The present invention is drawn to a liquid photocurable composition comprising: - from 25 to 65 % by weight relative to the total weight of the composition, of a mixture of polyfunctional acrylic monomers, said mixture consisting of (c) at least one monomer comprising at least six acrylic functional groups, and (d) at least one monomer comprising two, three or four (meth)acrylic functional groups, preferably two or three acrylic functional groups, - from 25 to 70 % by weight, relative to the total weight of the composition, of at least one organic solvent, - from 8.0 to 20.0 % by weight, preferably from 8.5 to 12 % by weight, relative to the total solids content of the composition, of at least one mineral conductive colloid, - from 0.5 to 5 % by weight, preferably from 1.0 4.0 % by weight, relative to the total weight of acryl functional monomers (a) and (b), of at least one radical photoinitiator, said photocurable composition not containing any epoxy-functional monomer. The present invention is also drawn to a method for preparing such a composition and for a method of producing antistatic hardcoatings on optical articles using such a composition.</p> |
