Abstract: Water-dissipative copolyesters are primer coatings for substantially amorphous polymeric films providing improved ink adhesion and improved slip characteristics. The primer coatings comprise copolyester having repeat units from a dicarboxylic acid component comprising 8 to 25 mole percent 5-sulfoisophthalic acid and 75 to 92 mole percent isophthalic acid and repeat units from a diol component comprising 25 to 100 mole percent diethylene glycol, 0 to 75 mole percent 1,4-cyclohexane-dimethanol, and 0 to 30 mole percent ethylene glycol, based on 100 mole percent dicarboxylic acid component and 100 mole percent diol component. The polymeric films are preferably polyester, polycarbonate or poly(vinyl chloride). These copolyesters primer coatings are generally dispersed in water or water/alcohol mixtures to a solids content of 20 to 35 weight percent.
