    摘要: A solvent based coating composition containing a binding agent, the binding agent comprising: (a) 10 to 80 wt.% of at least one hydroxyfunctional polyester formed by reacting a mixture comprising: (i) 10 to 40 mol.% of a 2,2-dialkylalkanediol with two primary OH groups; (ii) 10 to 30 mol.% of a polyol with at least one secondary OH group; (iii) 20 to 50 mol.% of an aliphatic or cycloaliphatic dicarboxylic acid with fewer than 16 C atoms or anhydrides thereof; (iv) 5 to 30 mol.% of a compound selected from the group consisting of dimeric fatty acids, dimeric diols, epsilon-caprolactone, and mixtures thereof; (v) 1 to 15 mol.% of a hydroxycarboxylic acid with at least one hydroxy group and at least one carboxyl group; and (b) 10 to 80 wt.% of a (meth)acrylic copolymer containing a hydroxyl group; and (c) 10 to 60 wt.% of a crosslinking agent; wherein the sum of the wt.% of components (a)-(c) is 100% of the binding agent.
