- aqueous coating compositions were sprayed over a water borne metallic base coat (Autowave ® ex Akzo Nobel Coatings BV) and allowed to dry at 60°C for 30 minutes. After one day the D.O.I, (distinction of image) and the gloss were measured in accordance with ASTM D-523 at 20° and 60°. The results are given in Table 5.

- Example 1a was repeated, except that the flask was filled with 500 g of the polyester resin of Comparison Example II, instead of 500 g of the polyester resin of Example 1 , after which there were added 10.2 g of N, N- dimethyl ethanol amine and 415.7 g of demineralised water.
- Example 1a The water borne polyester resin dispersions of Example 1a, Comparison Example la, Comparison Example lla, and Example 7b were submitted to a stability test in an oven at 35°C. The dispersions were about 3 weeks old at the start. The results are given in Table 6. Table 6
- polyester resin dispersions according to the invention are good to use after one year of storage at 35° C and give about the same coatings properties as freshly prepared dispersions.
- the polyester resin dispersions prepared according to the Comparison Examples (A and B) are no longer useful after 6 months of storage at 35°C.
