    Abstract: Zwitterionic copolymers, coating compositions (e.g., aqueous coating compositions and articles containing such copolymers, and methods of coating such coating compositions; wherein the copolymer includes: (a) first monomeric units derived from monomers of Formula (I) CH2═CR1—(CO)—X—R2—[-Q-R3—]n—Y (I) or salts thereof, wherein: R1 is hydrogen or methyl; X is oxy or —NH—; R2 is an alkylene optionally including catenary oxygen; R3 is an alkylene; Q is —(CO)O—, —NR4—(CO)—NR4—, or —(CO)—NR4—; R4 is hydrogen or alkyl; n is equal to 0 or 1; and Y is phosphonic acid, phosphonate, phosphoric acid, or phosphate; and (b) second monomeric units derived from monomers of Formula (II) CH2═CR1—(CO)—X—R2—[-Q-R3—]n—[NR5R6]+—R7—Z— (II) wherein: R1 is hydrogen or methyl; X is oxy or —NH—; R2 is alkylene optionally including catenary oxygen; R3 is alkylene; Q is —(CO)O—, —NR4—(CO)—NR4—, or —(CO)—NR4-; R4 is hydrogen or alkyl; n is equal to 0 or 1; R5 and R6 are each independently an alkyl, aryl, or a combination thereof, or R5 and R6 both combine with the nitrogen to which they are both attached to form a heterocyclic ring having 3 to 7 ring members; R7 is alkylene; and Z″ is carboxylate or sulfonate. CH2═CR1—(CO)—X—R2—[-Q-R3-]n—Y  (I) CH2═CR1—(CO)—X—R2—[-Q-R3—]n—[NR5R6]+—R7—Z−  (II)

    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: A UV curable composition for forming a polymeric coating on a substrate as described may include an optically clear colorless UV curable base comprising a combination of one or more multifunctional polymer precursor and a fluorinated polymer precursor. One or more of the multifunctional polymer precursor and fluorinated polymer precursor may comprise a non-charged electrically conductive site sufficient to disperse a static charge from the surface of the polymeric coating.
