Abstract
A continuous web of optical film laminate comprising, an optical film comprising a first substrate and an adhesive layer on the first substrate, a releasable film comprising a second substrate and a releasably treated layer on the second substrate, the releasably treated layer being in contact with the adhesive layer, a first conductive layer between the first substrate and the adhesive layer, and a second conductive layer between the second substrate and the releasably treated layer. The first conductive layer and the second conductive layer comprise a static electrification prevention material, such that the optical film with the first conductive layer, and the releasable film with the second conductive layer, both have a sheet resistance of 10Ω/sq or less.
