Abstract

The purpose of the present invention is to provide a white conductive primer coating composition with which it is possible to form, on a plastic base material, a coating film of high brightness and adequate conductivity. The present invention pertains to an aqueous white conductive primer coating composition that contains a binder component (A) and a carbon nanotube dispersion liquid (B), wherein: a coating film formed with said aqueous white conductive primer coating composition has a L* value of at least 80 according to whiteness based on the CIE color-matching function and has a surface electrical resistivity of 108 O/? or lower.
