<p>PROBLEM TO BE SOLVED: To obtain a controlling agent excellent in electrification stability and excellent in moisture resistance, light resistance and heat resistance by forming the agent using a metal salt of fullerene anions or a metal complex containing fullerene ligands. SOLUTION: This agent consists of a metal salt of fullerene anions or a metal complex. containing fullerene ligands. As for the fullerene, C60 , C70 and C84 are used, and especially C60 is preferable. As specific examples, metal complexes of ligand expressed by the formula are used. In the formula, R is an alkyl group or phenyl group both of which may have substituents, and preferably a subtd. or unsubstd. phenyl group. Substituents of the alkyl groups or phenyl groups are not specified as far as they are inert substituents which can be prepared as a Grignard reagent, and one or more substituents may be present. The inert substituents can be properly selected, and for example, methyl groups, ethyl groups, n-propyl groups, isopropyl groups can be used.</p> |
