An alkaline earth metal chelate complex of 2,2,6,6-tetramethylheptanedione of the formula (I) M2+(C11H19O2)-2.Lk(I) is described, in which M is calcium, strontium or barium, L is a ligand and k is a number from 1 to 3, the complex being free of water of hydration and the ligand L being an aliphatic ether having at least two oxygen atoms in the molecule. A process for the preparation of the chelate complex and its use for the production of coated substrates are also described.
