ABSTRACT:
Disclosed is a novel blend of a water-dissipatable polyester material, an acrylic polymer and a water-dissipatable vinyl polymer. The acrylic polymer and the vinyl polymer must be compatible with the polyester. The polyester is exemplified in having an acid component of from about 75 to about 84 mole % isophthalic acid and conversely from about 25 to about 16 mole % 5-sodiosulfoisophthalic acid, and having a glycol component of from about 45 to about 60 mole % diethylene glycol and conversely from about 55 to about 44 mole % 1,4-cyclohexanedimethanol or ethylene glycol or mixtures thereof.
The polymer blends are useful for preparing ink compositions having improved block resistance, water resistance, and alcohol resistance.
