Abstract: The invention relates to the use of salts of sulfosuccinic acid esters as internal antistatic agents, take-off and winding aids for transparent cast films of polycarbonates, to a process for the production of cast polycarbonate films and to the cast polycarbonate films themselves containing salts of sulfosuccinic acids and also to the use of the new cast polycarbonate films in the electrical field and optical field.
