A coating composition comprising:
- a) at least one binder B containing an ethylene copolymer, said ethylene copolymer comprising—in polymerized form and based on a total weight of the ethylene copolymer—
- i. 10 to 80 wt. % of ethylene;
- ii. 1 to 90 wt. % of at least one polymerizable compound C1 comprising at least one hydroxyl group and/or 1 to 80 wt. % of at least one polymerizable compound C2 comprising at least one epoxide group;
- and
- iii. 0 to 80 wt. % of at least one further polymerizable compound C3 different from compounds C1 and C2;
- and
- b) at least one crosslinking agent CA comprising at least one reactive functional group which is able to undergo crosslinking reactions with complementary reactive functional groups present in the at least one binder B.
