Patent ID: 7015279

Claim:
A self-reversible invert latex, comprising: a) an oily phase, b) an aqueous phase, c) at least one water-in-oil type emulsifying agent, d) at least one oil-in-water type emulsifying agent, and e) a cationic polyelectrolyte. wherein said cationic polyelectrolyte composition comprises a plurality of copolymerized monomeric units of at least one cationic monomer with at least one neutral monomer and at least one nonionic surfactant monomer, wherein said cationic polyelectrolyte composition present is in a range of from about 20% to about 70% by weight of said self-reversible invert latex, wherein: of said copolymerized monomeric units comprise said cationic monomer; b) from about 55% to about 95% of said copolymerized monomeric units comprise said neutral monomer; and c) from about 0.1% to about 5% of said copolymerized monomeric units comprise said nonionic surfactant monomer, a) from about 5% to about 35% of said copolymerized monomeric units comprise said cationic monomer; b) from about 35% to about 91% of said copolymerized monomeric units comprise said neutral monomer; c) from about 0.1% to about 5% of said copolymerized monomeric units comprise said nonionic surfactant monomer; and d) from about 3% to about 20% of said copolymerized monomeric units comprise said N-[2-hydroxy-1,1-bis(hydroxymethyl)ethyl]propenamide monomer.
