Abstract
A cathodic electrocoating paint composition that yields solvent-resistance films is shown. The paint binder consists essentially of: PA0 (a) synthetic cation-active latex and resinous pigment dispersant that is crosslinkable therewith, with the proviso that when said dispersant is substantially in excess of about 15% of said latex, an external crosslinker is present that will crosslink upon curing with at least said dispersant; or PA0 (b) synthetic cation-active latex and resinous pigment dispersant that is not crosslinkable therewith and external crosslinker that will crosslink with both said latex and said dispersant.
