  • Latex functionalized with phosphorus acid and photoinitiator groups
    Patent number: 10221270
    Abstract: The present invention is a composition comprising a stable aqueous dispersion of polymer particles comprising structural units of a phosphorus acid monomer or a salt thereof and structural units of a photoinitiator monomer. Gloss retention of paints containing the latex described herein is markedly improved over paints that do not have photoinitiator chemically bound to the latex particles.
