A release agent and a release liquid which are used for the manufacture of labels, double-sided tapes, etc., are disclosed. The release agent and the release liquid provide improved adhesion between a substrate and a release layer, and excellent peel strength betwveen the release layer and an adherent. The release agent includes a dispersion of a vinyl-modified colloidal silica, a dispersion of a platinum chelate catalyst, and a polysiloxane water-dispersible silicone emulsion. The release liquid is obtained by dispersing the release agent in water so as to have a solid content of 2.5~30% by weight. The release film is produced by applying the release liquid on a substrate, followed by drying. |
