Description of the Invention (Technical Field) The present invention relates to a release composition, and more particularly, to a radiation-curable silicone release coating composition comprising a surface-treated Particulate solids. BACKGROUND OF THE INVENTION For example, a release coating composition is used to coat a paper or film used as a backing sheet (sometimes referred to as a protective release sheet or release liner). Products, such as: pressure sensitive adhesives for labels, transfer paper, tape, etc. The pressure-sensitive adhesive is adhered to the release-coated surface of the release substrate, which is sufficient to enable the pair of pressure-sensitive products to be processed before use. When using this product, the release substrate was torn off and discarded. The exposed pressure-sensitive adhesive is pressed onto the surface to which the pressure-sensitive product is to adhere. Known types of release substrates include paper-based release substrates in which one side (release side) of the paper is coated with a silicone polymer or copolymer. Silicone polymers and copolymers have been widely used as release layers for paper, films, etc. because of their inherently low surface energy. It is desirable that the silicone-coated release paper and film have a sufficiently low peel force, so that the release substrate can be easily removed from the pressure-sensitive adhesive-coated substrate, but not so low as to make the release substrate, It is separated from the pressure-sensitive adhesive before it is generally exposed to external forces such as processing and printing, die-cmting, and substrate peeling. " Peeling force " is defined as the force required to tear or separate the release-coated substrate from the adhesive.

Radiation-cured polymers have many advantages over heat-cured polymers. Advantages include better adhesion to certain substrates, 'higher curing speeds, and lower high-speed peeling. However, the cost of radiation-cured polymers is significantly greater than that of polymers typically cured by heat. This has the advantage of providing the radiation curable polymer in the form of a polymer that reduces the amount of polymer required for a particular application, but still maintains the effectiveness of the polymer. Functional group-containing polyorganosiloxanes that can be radiation-cured in the presence or absence of a photosensitizer have been disclosed in various patents as effective silicone release compositions. U.S. Patent No. 3,726,710 describes a radiation-curable release composition containing a polyorganosiloxane having an olefin-based unsaturated organic group, and a photosensitizer. The composition can be applied to a paper substrate and cured by exposure to high intensity radiation, resulting in a release coating.
