A clearcoat coating material composition comprising at least one OH-functional (meth)acrylic copolymer as constituent, at least one branched OH-functional polyester as constituent, which is obtainable by performing steps (a), (b) and (c), namely by (a) reacting at least one polyol comprising at least three OH-groups with at least one aliphatic dicarboxylic acid having from 6 to 36 carbon atoms and/or an anhydride and/or ester thereof to form a OH-functional first intermediate product; (b) reacting the first intermediate product obtained from step (a) with at least one cyclic carboxylic acid anhydride to form a carboxylic acid-functional second intermediate product; and (c) reacting the second intermediate product obtained from step (b) with at least one epoxide-functional compound having one epoxide group to form the branched OH-functional polyester, and at least one crosslinking agent as constituent, which is different from both constituents and and which contains crosslinkable functional groups, which can be at least crosslinked with OH-functional groups, wherein the at least one branched OH-functional polyester is present in the clearcoat coating material composition in an amount in the range of from 1.0 wt.-% to 15.0 wt.-%, based on the total solids content of the coating material composition. at least one OH-functional (meth)acrylic copolymer as constituent, at least one branched OH-functional polyester as constituent, which is obtainable by performing steps (a), (b) and (c), namely by (a) reacting at least one polyol comprising at least three OH-groups with at least one aliphatic dicarboxylic acid having from 6 to 36 carbon atoms and/or an anhydride and/or ester thereof to form a OH-functional first intermediate product; (b) reacting the first intermediate product obtained from step (a) with at least one cyclic carboxylic acid anhydride to form a carboxylic acid-functional second intermediate product; and (c) reacting the second intermediate product obtained from step (b) with at least one epoxide-functional compound having one epoxide group to form the branched OH-functional polyester, and (a) reacting at least one polyol comprising at least three OH-groups with at least one aliphatic dicarboxylic acid having from 6 to 36 carbon atoms and/or an anhydride and/or ester thereof to form a OH-functional first intermediate product; (b) reacting the first intermediate product obtained from step (a) with at least one cyclic carboxylic acid anhydride to form a carboxylic acid-functional second intermediate product; and (c) reacting the second intermediate product obtained from step (b) with at least one epoxide-functional compound having one epoxide group to form the branched OH-functional polyester, and at least one crosslinking agent as constituent, which is different from both constituents and and which contains crosslinkable functional groups, which can be at least crosslinked with OH-functional groups, wherein the at least one branched OH-functional polyester is present in the clearcoat coating material composition in an amount in the range of from 1.0 wt.-% to 15.0 wt.-%, based on the total solids content of the coating material composition.
