PURPOSE:A composition that is obtained by combining a specific AS resin or a rubber-modified AS resin with an electroconductive substance, thus having high electroconductivity and improving its appearance of the formed product therefrom or of the coated product after forming, without any adverse effect on its impact strength. CONSTITUTION:(A) A rubber-modified thermoplastic resin which is prepared by polymerizing at least one selected from aromatic vinyl monomers and at least one selected from vinyl cyanides monomers, when necessary, at least one from other monomers copolymerizable with at least one of the above-cited monomers in the presence of a rubber-like polymer and/or a copolymer from the above- cited monomers, in which the content of vinyl cyanide components is 24-35wt%, preferably 28-35wt% in the fraction soluble in acetone in the thermoplastic resin, is combined with (B) an electroconductive substance so that its content is 3-25vol%.
