Method for producing release film using silicone aqueous emulsion release liquid

Not applicable. A method for producing a release film which is used for the manufacture of adhesive labels, double-sided tapes, etc., is disclosed. The release film provides improved adhesion between a substrate and a release layer, and excellent peel strength between the release layer and an adherent. The method includes the steps of : obtaining a silicone aqueous emulsion release liquid by dispersing a silicone aqueous release agent including a dispersion of a vinyl-modified colloidal silica, a dispersion of a platinum chelate catalyst and a polysiloxane water-dispersible silicone emulsion, in water, so as to achieve a solid content of the release liquid of 2.5˜30% by weight; and applying and drying the obtained release liquid on a substrate to form a release layer.
