Abstract:
1. An aqueous primer composition which comprises: (A) an aqueous dispersion of modified polyolefin which comprises an unsaturated carboxylic acid- or acid anhydride-modified polyolefin (a) having a melting point of 120° C. or lower and a weight average molecular weight of 30,000 to 180,000, dispersed in an aqueous medium, (B) an ionic functional group-containing acrylic resin, and (C) a conductive carbon-containing pigment, which forms a coating film with an L value of 35 or more and a surface resistivity of 1×10 wherein the ionic functional group-containing acrylic resin (B) has at least one species of ionic functional group selected from tertiary amino group and quaternary ammonium base, and has an ionic functional group containing unsaturated monomer unit in an amount ranging from 1 to 40 mole %.
