摘要： The present invention relates to a coating composition comprising a blend of polyesters, said blend comprising:—from 0.1 to 99.9% by weight of one or more saturated polyesters (A) and—from 99.9 to 0.1% by weight of one or more unsaturated polyesters (B), based on the total weight of polyesters (A) and (B); said one or more (A) and one or more (B) having a Weight Average Molecular Weight (Mw) of at least 15,000 g/mole, as measured by Gel Permeation Chromatograph using tetrahydrofuran as solvent, and a glass transition temperature, as measured by Differential Scanning Calorimetry, according to DIN EN 61006, method A, of at least 60° C. The present invention also relates to a high molecular weight polyester as such, the method for producing a coated substrate, the coated substrate as such, and use of the coating composition.
