PURPOSE:To obtain the titled coating with low sliding noise level even after the lapse of high-sliding working life, capable of reduction in the silver content in said coating, suitable for high-performance electrical radiation-absorption panelboards, etc., by incorporating a synthetic resin with electrically conductive powder comprising silver powder and tri-iron tetroxide powder. CONSTITUTION:The objective coating can be obtained by blending (A) electrically conductive powder comprising (i) silver powder and (ii) tri-iron tetroxide powder in a weight ratio (i)/(ii) of pref. 95:5-47:53 and (B) a synthetic resin and furthermore, if needed, (C) other ingredient(s).
