Patent ID: 6984675

Claim:
An aqueous dispersion, comprising: (A) a sulfopolyester formed as a polycondensation product of: (1) a first reaction mixture comprising: (a) at least about 70 mol. % of terephthalic acid or an ester thereof, and (b) about 4–20 mol. % of a difunctional ester forming sulfomonomer containing at least one metal sulfonate group attached to an aromatic nucleus, and functional groups selected from the group consisting of hydroxyls, carboxyls and alkyl esters; and (2) a second reaction mixture comprising ethylene glycol, diethylene glycol and triethylene glycol, at least about 20 mol. % of the second reaction mixture being ethylene glycol; and (B) an addition polymer formed in situ on the sulfopolyester from polymerizing styrene monomer.
