    Abstract: Emulsion polymers and coating compositions made therefrom that exhibit exceptional roller stability and stain resistance to both hydrophilic and hydrophobic stains, without sacrificing scrub resistance. The emulsion polymers include, as polymerized units formed at a pH between 3 and 9: a) at least one nonionic or anionic unsaturated monomer in an amount ranging between about 78 wt. % to less than 100 wt. % based on the overall weight of the polymer composition b) one or more strong acid monomer in an amount ranging from about 0.01 wt. % to 2 wt. % based on the overall weight of the polymer composition; and c) at least one lower alkyl acrylate monomer in an amount ranging between about 1 wt. % to 20 wt. % based on the overall weight of the polymer composition.

    Abstract: Waterborne dispersions including crosslinkable multistage polymeric particles useful in coating compositions are provided. The multistage particles have a last-formed layer that includes a diketone functionality that is capable of crosslinking via a dihydrazide component also included in the dispersion. Another embodiment of the waterborne dispersion further includes crosslinkable latex particles having a diketone functionality that are capable of crosslinking with each other and/or the multistage particles via the dihydrazide component. An emulsion polymerization process for forming the multistage particles also is provided. Also provided are coating compositions that contain either embodiment of the waterborne dispersions.
