ABSTRACT:
An electrically conductive thermoplastic resin and coating composition comprising a diphosphonic acid derivative having the formula: ##STR1## wherein R represents an alkyl or aryl group and M.sup.1 to M.sup.4 independently represent hydrogen or a cation.
The electrically conductive thermoplastic resin composition has excellent electrical conductivity and retains the electrical conductivity for extended periods without using expensive noble metals. Furthermore, the electrically conductive coating composition provides an excellent electrical conductivity and shielding property retention without using expensive noble metals.
