Abstract
Disclosed herein are nonionic resin compositions that are polymerized without acid monomer or substantially without acid monomer. The nonionic resin compositions are compatible with cationic additives to lock stains. Primer and topcoat paint compositions containing such compositions are resistant to stains migrating to the top of the paint films.

A substantially nonionic latex resin polymerized from:
- a monomer mixture comprising at least one nonionic (meth)acrylate monomer, a polymerizable nonionic hydrophilic component, wherein the monomer mixture comprises less than 0.25 wt. % of acid monomer or other monomers with anionic groups, and
- a nonionic surfactant ranging from about 1 wt. % to about 4 wt. %;
- and
- wherein the polymerizable hydrophilic component is present from about 1.5 wt. % to about 3.5 wt. %,
- wherein the weight percentages are without water, and
- wherein the polymerizable hydrophilic component comprises a polymerizable polyethylene glycol monomer or a polymerizable polypropylene glycol monomer.
A substantially nonionic latex resin polymerized from:
- a monomer mixture comprising at least one nonionic (meth)acrylate monomer, a polymerizable nonionic hydrophilic component, wherein the monomer mixture is comprises less than 0.25 wt. % of acid monomer or other monomers with anionic groups, and
- a nonionic surfactant ranging from about 1 wt. % to about 4.5 wt. %, wherein a HLB value of the nonionic surfactant ranges from about 14 to about 18,
