The present invention provides a solvent-free silicone composition that provides a cured film having excellent adhesion to a substrate, particularly a plastic film substrate, and capable of leaving high adhesive strength on the adhesive material after peeling the adhesive material from the cured film and to provide a release paper and a release film provided with the cured coating film, (A) having two or more alkenyl groups bonded to silicon atoms in one molecule, and one aryl group in one molecule Organopolysiloxane (B1) with or without more than three hydrogen atoms bonded to a silicon atom in one molecule, and an aryl group, in the total number of hydrogen atoms bonding to silicon atoms and groups bonding to silicon atoms (B1) with respect to the number of alkenyl groups in the organohydrogenpolysiloxane (A) component having a ratio (%) of the total number of aryl groups to the number (hereinafter referred to as the ratio of aryl groups) at least 8% It contains an amount such that the ratio of the number of SiH groups in the component is 0.5 to 10, and (C) a catalyst amount of a platinum group metal catalyst, [ratio (%) of the aryl groups in component (B1)]-[in component (A) The ratio of the total number of aryl groups to the total number of groups bonded to silicon atoms (%)] ≥ 8. |
