摘要：A nitrogen-containing compound of the following general formula (1) iskneaded into a resin molding material, the kneaded mixture is molded and the surface ofthe resulting article is subjected to corona discharge treatment. Further, a coatingmaterial having electrostatic charges is sprayed and deposited on the article after thecorona discharge treatment. This can provide a shaped resin article with remarkablyimproved electrical conductivity from a less electrically conductive resin, withoutsubstantially deteriorating the physical properties and the color of the article. Further,electrostatic coating excellent in coating efficiency, surface appearance, productivity orthe like is possible. ##STR1## where R.sup.1 represents an alkyl group or alkenyl groupof 5 to 21 carbon atoms, R.sup.2 represents --H or --CH.sub. 3, R.sup.3 and R.sup. 4 maybe the same or different and each represents an alkyl group of 1 to 4 carbon atoms, Arepresents --(CH.sub.2).sub.n -- or ##STR2## and n is 1 to 5.
