Description

ABSTRACT:
An aqueous composition comprising resin and pigment for use in an acidic aqueous coating composition, wherein substantially all the resin is associated with pigment, such that when said coating composition is applied to a metallic surface a resinous coating having uniform color is formed; the acidic aqueous coating composition, having resin and pigment therein, is of the type which forms on a metallic surface immersed therein a resinous coating which increases in thickness or weight the longer the time the surface is contacted with the coating composition; aqueous resin/pigment concentrate for use in the coating composition is prepared by combining an aqueous dispersion of resin solids with an aqueous dispersion of pigment solids in a manner such that substantially all of the resin solids have substantially the same opportunity to associate with the pigment solids.
