at least one organic phosphorus compound of the following general formula (I) or (II):
wherein the residues R
1
, R
2
, and R
3
each independently represent organic or inorganic residues,
and that said sulfur compound is
elemental sulfur and/or
at least one inorganic or organic sulfur compound and/or sulfur-containing compound.
