Abstract: The invention illustrates herein several tests among various manufacturing methods and tests carried out by the inventors according to the method of manufacturing a silicone release polyester film. It should be noted that the technical spirit of the invention shall not be limited or restricted thereby, and can be modified and carried out variously by those skilled in the art. As described in the above, the silicone release polyester film according to the invention is very good in stabilization for pass-the-time and also very good in the property of rub-off after thermal ripening by improving adhesiveness between the polyester layer and the silicone layer by olgano resin having the vinyl radical in the silicone film layer. By improving easiness of release destruction behavior with the adhesive used for release by containing the olgano resin having the vinyl radical in hexenyl polysiloxane, the silicone release polyester film can be used for electronics and the field requiring uniform release.
