FIELD: chemistry. ^ SUBSTANCE: invention relates to a coating composition containing a) polyacrylate polyol obtained via polymerisation of unsaturated olefin monomers, where at least 40 wt % of the monomers include straight or branched alk(en)yl or alk(en)ylene groups, having at least 4 carbon atoms; b) polyether polyol obtained via esterification of component links having functional groups which form an ester, where at least 30 wt % of component links include straight or branched alk(en)yl or alk(en)ylene groups with at least 4 carbon atoms per functional group, which forms an ester, where he polyether polyol has hydroxyl number higher than 280 mg KOH/g and hydroxyl functionality of at least 2, and c) isocyanate-functionalised cross-linking agent. The invention also relates to a set of parts for preparing the coating composition and a method of applying the coating composition. The coating composition can be used as a top coating layer in multilayer paint coats, in finishing or reworking automobiles or large vehicles. ^ EFFECT: coating has high hardness, scratch resistance, lustre, longevity and wear resistance, chemical resistance and UV radiation resistance. ^ 15 cl, 6 tbl |
