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.
where R1 represents an alkyl group or alkenyl group of 5 to 21 carbon atoms, R2 represents -H or -CH3, R3 and R4 may be the same or different and each represents an alkyl group of 1 to 4 carbon atoms, A represents -(CH2)n- or
and n is 1 to 5.
将以下通式(1)的
含氮化合物捏合到
树脂成型材料中,然后将捏合混合物成型,并对成型物品的表面进行电晕放电处理。此外,在电晕放电处理后,在制品上喷涂和沉积具有静电荷的涂层材料。这样就可以用导电性较差的
树脂制成导电性能显著提高的成型
树脂制品,而不会严重影响制品的物理性能和颜色。此外,静电涂层在涂层效率、表面外观、生产率等方面也有可能得到改善。
