The present invention provides a polyester which is the reaction product of reactants comprising: (A) an aliphatic dicarboxylic acid comprising from 16 to 30 carbon atoms; (B) an aromatic carboxylic acid and/or anhydride; and (C) a polyol. The invention also provides a coating composition comprising the polyester, a method of making the coating composition and the use of at least 2 wt% of a linear aliphatic dicarboxylic acid comprising from 16 to 30 carbon atoms as a replacement for at least 2 wt% of an aromatic carboxylic acid and/or anhydride in a polyester composition. This use may improve the UV resistance and/or stability of the polyester composition. |
