The invention relates to hydroxypyridinone derivatives, their metal complexes, their preparation and their use for preparing conjugates with biomolecules. The conjugates are suitable as contrast agents in NMR diagnosis. A high relaxivity is achieved and the NMRD maximum is raised through a specific design of the ligands.
