Abstract
The present invention provides a water-dilutive and conductive coating composition capable of preparing any desired color tone which, upon applying to a thing to be coated, affords various beautiful color tones, gives electroconductivity and prevents static electricity and particularly offers a composition capable of preparing any desired color which can be effectively used in a place where the use of organic solvents and chemical contamination are strictly restricted such as factories for the manufacture of semiconductors. The invention provides a water-dilutive and conductive coating composition whereby any desired color can be afforded, characterized in that, said composition contains 10-50% by weight of water-soluble or water-dispersible synthetic resin (non-volatile content) and 5-40% by weight of white electroconductive pigment and the amount of each of sodium and potassium, in the resulting coated film is not more than 30 ppm.
