Abstract
An antimony-containing tin oxide wherein the content of antimony is 0.1 to 20% by weight is almost white and excels in electric conductivity. By mixing a powder of this antimony-containing tin oxide of a particle size of 0.4 .mu.m or less with a binder resin in a specific ratio, an antistatic coating composition can be obtained. By applying this coating on nonconductive base materials such as electronic/electrical parts and building members, an antistatic effect can be imparted to these base materials without impairing their color tones.
Claims12
An antistatic, transparent film-forming liquid coating composition comprising a thermoplastic or thermosetting binder resin and an electroconductive powder of 5 to 90% by weight based on the total quantity of said binder resin and said powder, said electroconductive powder comprising an antimony-containing tin oxide wherein the antimony content is 0.1 to 20% by weight and having a particle size of 0.4 .mu.m or less, said antimony being present as Sb.sub.2 O.sub.3 or Sb.sub.2 O.sub.5 or mixtures thereof.
