Abstract

Disclosed are coating material compositions including (i) at least one polyol component (A), (ii) at least one crosslinking agent component (B) having groups reactive toward hydroxyl groups of component (A), (iii) at least one polyamide component (P1) in which the acid amide groups are connected by a saturated, aliphatic hydrocarbyl radical having 6 to 10 carbon atoms. Component (P1) is used in particulate form in which a size distribution (D50) is 20 to 100 μm. The coating material compositions further include (iv) at least one polycarboxamide component (P2) possessing the following structural formula in which s is 1, 2 or 3, t is 0 or 1, s+t is 2 or 3, R is a specific (s+t)-valent organic radical, and at least one of the radicals R1 and R2 carries at least one hydroxyl group. Also disclosed are methods of producing the coating material compositions.
