Pyrazol(5)/pyrazolone(5)metal complexes as stabilizers for organic
materials
摘要:
The present invention concerns novel pyrazole (5) pyrazolone (5) metal complexes of the formula ##SPC1##Wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are substituents and Me is a transition metal,Useful in stabilizing sensitive organic material against the degradative effect of U.V. light.
