    摘要： The present invention relates to polyester polyols comprising units derived from



    a) at least one component (A) carrying at least one COOH group or a derivative thereof, wherein component (A) comprises

    (i) at least one compound carrying two COOH groups or derivatives thereof (A1), and


    b) at least one component (B) carrying at least one OH group and no COOH group, wherein component (B) comprises

    (ii) optionally at least one compound or oligomer carrying at least three OH groups and no COOH group (B1),
    (iii) at least one compound carrying two OH groups (B2) of formula














    wherein n and m are independently from each other 0 or 1, and R1 and R2 are independently selected from the group consisting of H, CH3 and CH2CH3, and
    (iv) optionally at least one compound, oligomer or polymer carrying two OH groups and no COOH group, which is different from B2 (B3),


    and to an organic solvent-based two-component coating composition comprising
    a) a first component (K1) comprising (i) at least one polyester polyol of the present invention, and (ii) optionally at least one polymer carrying more than one OH group, which is different from the polyester polyol of the present invention, (D), and
    b) a second component (K2) comprising (i) at least one compound, oligomer or polymer carrying more than one N═C═O group or blocked N═C═O group (F),
    to substrates coated with the coating composition, and to coating layers on a substrate formed from the coating compositions.
