Abstract
The present invention concerns novel nickel complexes (I) possessing U.V. stabilizing properties characterized by bearing per molecule 2 monodentate nickel coordinated 1,3-hydrocarbyl-4-(greater than C.sub.1)-acyl-pyrazole-5-oxy ligands and one bidentate or two monodentate nickel coordinated primary or secondary amine ligands, and their use as U.V. stabilizers for e.g. plastics materials.
