Release film furnished on at least one side with a release layer (c) based on at least one cured polysiloxane, the film comprising at least one inner layer (a) based on at least one thermoplastic polymer, equipped with at least one at least oligomeric compound having a long-term antistatic effect, as antistat, and at least one layer (b) based on at least one thermoplastic polymer; method for producing the release film, and the use thereof as a detachable protective or masking film. 2. A release film as claimed in claim 1 , wherein at least one polymer with long-term antistatic effect is present as antistat.3. A release film as claimed in claim 1 , wherein at least one intrinsically conducting polymer is present as antistat claim 1 , the polymer being in each case doped claim 1 , or at least one polyetherpolyamide block copolymer.4. A release film as claimed in claim 1 , wherein at least one intrinsically conducting polymer is present as antistat claim 1 , the polymer being in each case doped claim 1 , and the polymer being selected from the group consisting of polyacetylenes (PAC) claim 1 , polyanilines (PANI) claim 1 , polypyrroles (PPy) claim 1 , poly-para-phenylenes (PPP) claim 1 , poly-para-phenylene sulfides (PPS) claim 1 , polyphenylenevinylenes (PPV) claim 1 , polyfluorenes (PFO) claim 1 , and polythiophenes (PT).5. A release film as claimed in claim 1 , wherein at least one intrinsically conducting polymer is present as antistat claim 1 , which is doped with a dopant selected from the group consisting of halogens claim 1 , perchlorates claim 1 , peroxides claim 1 , persulfates claim 1 , alkali metals claim 1 , alkaline earth metals claim 1 , organic acids and acid anhydrides claim 1 , inorganic acids claim 1 , and polymer-bonded dopants.6. A release film as claimed in claim 1 , wherein the inside layer (a) has 11%-16% by weight claim 1 , based on the total weight of the layer (a) claim 1 , of the antistat.7. A release film as claimed in claim 1 , wherein the ...
