The present invention relates to sulfonate containing water-dispersible or water-dissipatible sulfo-polyester compositions. The sulfo- polyesters of the present invention have a glass transition temperature of greater than 89 °C. In addition, the sulfo-polyesters have a dicarboxylic acid component of poly(ethylene-2,6-naphthalene dicarboxylate) and a sulfo-monomer, and a diol component of at least 35 mole percent of a diol selected from ethylene glycol, 1,4-cyclohexanedimethanol, propane 1,2-diol and 2,2-dimethyl-1,3-propanediol. The sulfo-polyesters of this invention are useful in applications where increased abrasion resistance, inherent higher temperature process conditions, and improved blocking resistance are required such as in adhesives, coating materials, sizes, laminated products, aqueous printing inks, and films.
