| titleOfInvention | Coatings based on polyisocyanates and aliphatic aldimines that have improved mar and scratch resistance |
| abstract | The present invention is directed to coatings that have good scratch and mar resistance and are prepared from coating compositions containing a) a polyisocyanate component containing i) 0 to 25% by weight of allophanate groups (calculated as HC2N2O3, MW 101) and/or ii) 0 to 25% by weight of uretdione groups (calculated as C2N202, MW 84), b) an aldimine corresponding to the formula X1-[N=CHCH(R1)(R2)]n wherein X1 represents the residue which is inert towards isocyanate groups at a temperature of 100°C or less and is obtained by removing the amino groups from an aliphatic polyamine having n amino groups and a molecular weight of less than 400 and R1 and R2 may be identical or different and represent organic groups which are inert towards isocyanate groups at a temperature of 100°C or less, or R1 and R 2 together with the .beta.-carbon atom form a cycloaliphatic or heterocyclic ring, n represents an integer with a value of at least 2, wherein components a) and b) are present in an amount sufficient to provide an equivalent ratio of isocyanate groups to aldimine groups of 0.5:1 to 5:1. |
