<p>PURPOSE:To obtain the titled film having stable releasability and small variation of releasability with time, by reacting an organopolysiloxane containing an aliphatic hydrocarbon with a hydrogen polysiloxane in the presence of a platinum-based catalyst and contacting the resultant film with a specific compound. CONSTITUTION:An organopolysiloxane containing an aliphatic unsaturated hydrocarbon group bonded to Si atom is subjected to addition reaction with an organohydrogen polysiloxane having H atom bonded to Si atom in the presence of a platinum-based catalyst to form a releasing silicone film on the surface of a substrate. The objective film is produced by contacting the surface of the film with an organotin compound (preferably dibutyltin diacetate, etc.). The addition reaction is carried out preferably by heating at 60-200 deg.C for 5-30sec.</p> |
