Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polymer thick film positive temperature coefficient carbon resistor composition.SOLUTION: This invention relates to a polymer thick film positive temperature coefficient carbon resistor composition comprising: (a) organic medium comprising (i) organic polymeric binder; and (ii) solvent; and (b) conductive carbon powder. The composition may be processed at a time and temperature necessary to remove all solvent. The invention is further relates to: PTC circuits comprising the composition which has been dried to remove the solvent; and articles, e.g., mirror heaters and seat heaters, containing such PTC circuits.
