Abstract
The present invention concerns the use of starch derivatives, wherein the starch derivative is partially acetylated and partially acylated with at least one fatty acid, as additive in coating compositions, and starch derivatives which are partially acetylated and partially acylated with at least one fatty acid at least one fatty acid, wherein the MW of the starch derivatives is from 3.000 to 50.000 g/mol.

A coating comprising:
- an additive comprising:
- at least one starch derivative,
- wherein the at least one starch derivative is
- partially acetylated, and
- partially acylated with at least one fatty acid,
- wherein the at least one fatty acid is at least one of palmitic acid, oleic acid, or any combination thereof;
