Abstract: A coating composition, effective in emitting heat without breaking down when connected to a source of electricity, is formulated from a binder; an electrically conductive carbon black particle generated by high temperature pyrolysis of acetylene and having a particle size between of between about 5 and 500&mgr;; an electrically conductive graphite particle having a degree of crystallinity of at least about 67% and having a particle size between about 5 and 500&mgr;; and a volatile solvent. The weight amount of (b) and (c) together ranges from between about 10 and 75 weight-% based on the non-volatile solids content of the coating composition.
