摘要： A nitrogen-containing compound of the following general formula (1) is kneaded into a resin molding material, the kneaded mixture is molded and the surface of the resulting article is subjected to corona discharge treatment. Further, a coating material having electrostatic charges is sprayed and deposited on the article after the corona discharge treatment. This can provide a shaped resin article with remarkably improved electrical conductivity from a less electrically conductive resin, without substantially deteriorating the physical properties and the color of the article. Further, electrostatic coating excellent in coating efficiency, surface appearance, productivity or the like is possible. ##STR1## where R.sup.1 represents an alkyl group or alkenyl group of 5 to 21 carbon atoms, R.sup.2 represents --H or --CH.sub.3, R.sup.3 and R.sup.4 may be the same or different and each represents an alkyl group of 1 to 4 carbon atoms, A represents --(CH.sub.2).sub.n -- or ##STR2## and n is 1 to 5.

摘要： A nitrogen-containing compound of the following general formula (1) is kneaded into a resin molding material, the kneaded mixture is molded, and the surface of the resulting article is subjected to corona discharge treatment. Then, an electrostatically charged coating is sprayed on the article. ##STR1## wherein R.sup.1 represents an alkyl group of 6-22 carbon atoms, R.sup.2 and R.sup.3 may be the same or different and each represents an alkyl group of 1-4 carbon atoms; n represents 2-3. In accordance with this invention, a shaped resin article with remarkably improved electrical conductivity can be obtained from a resin of low electrical conductivity substantially without affecting the physical properties and color of the resin and with high productivity. Furthermore, a resin article with high surface resistivity can be electrostatically coated with high coating efficiency and improved results in appearance and productivity substantially without affecting the physical properties of the resin.
