Method for filtering carrier oil

One embodiment is directed to an adhesive composition that is clear, flexible, and is devoid of non-polar additives and comprises molecules that are polar and particles having a lipophilic surface. In one embodiment, the particles range from 7 nm to 3 &mgr;m in diameter and the adhesive layer is between 0.1 and 5 &mgr;m thick. The particles may be alkyl-converted fumed silica, porous polymer-coated surfaces, or styrene/divinyl benzene polymer. The particles absorb non-polar oils or lubricants that prevent adhesion between printable media and the adhesive layer of the film. The present disclosure is a general solution for oily or lubricated substrates or printed areas. Oily materials are used in inks, dry powder toners, liquid EP toners, and in printers and copiers. The present teachings allow the adhesive to bond well to print media surfaces.
