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 first polyesters, based on the total solid content of the dispersion, wherein said one or more first polyesters have an acid number in the range of from less than 15, for example less than 10, or in the alternative less than 5, based on the total solid content of the one or more first polyesters; (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 has a carboxylic acid group and an acid number equal to or greater than 15, for example greater than 20, based on the solid content of the second polyester; (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) one or more cross-linking agents.
