Abstract (en)
[origin: WO2022238315A1] The present invention relates to polyester polyols (1) carrying at least one group selected from a group including formula (I) and formula (I´) wherein R1 and R2 are indenpendently and at each occurrence a residue comprising 1 to 20 carbon atoms, with the proviso that R1 is not -CH2-CH2-O-C(=O)-CH=CH2 or -CH2CH2-O-C(=O)-C(CH3)=CH2, to solutions comprising at least one polyester polyol (1) and at least one organic solvent, to a process for the preparation of the polyester polyol (1), to intermediate monoisocyanates used in this process, to an organic solvent-based two-component coating composition comprising a) a first component (K1) comprising (i) the polyester polyol (1) and (ii) optionally at least one polymer carrying more than one OH group, which is different from the polyester polyol (1) of the present invention (D1), 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 (F1), and to substrates coated with this coating composition.
