Abstract

The instant invention provides an aqueous dispersion, a coating composition, coating layers and coated article made therefrom. The coating composition according to the present invention comprises: (1) the inventive aqueous dispersion comprising the melt blending product of: (a) from 50 to 99 percent by weight of one or more polyethylene terephthalate resins, based on the total solid content of the dispersion; (b) from 1 to 50 percent by weight of one or more stabilizing agents comprising at least one second polyester, based on the total solid content of the dispersion, wherein said second polyester (i) has a carboxylic acid group and an acid number equal to or greater than 15, based on the solid content of the second polyester; or (ii) is a self-dispersing sulfopolyester; (c) one or more neutralizing agents; and (d) from 15 to 90 percent by weight of water, based on the total weight of the dispersion; wherein said dispersion has a solid content of 10 to 85 percent, based on the total weight of the dispersion; and (2) optionally one or more cross-linking agents.
