ABSTRACT OF THE INVENTION Mechanical stability and costing characteristics of structurally cation-active, film-forming latex, especially useful in electrodeposition coatings can be improved by the addition of small stabilizing amounts of linear cationic amine-modified epoxy resin having tertiary amine functionality and base number in the range of 30-500 and/or glycol mono-substituted ether alcohols. "Stability" is defined by the absence of agglomerated latex particles as shown by disc centrifuge photosedimentometer traces after subjecting the latex to 30 minutes of mechanical shear using a Hamilton Beach mixer. Such stabilized latex remains substanti- ally non-agglomerated even after being subjected to pumping and shear. Without the stabilizer, agglomeration of the latex occurs.
