Abstract: The present invention teaches an antimony free brominated flame retardant composition, comprising a brominated flame retardant, an organic phosphorus-containing flame retardant which is an organic phosphate that is either an amorphous solid or a liquid, and a flame retardant which is a source of nitrogen and inorganic phosphorus, this source being amorphous compound. The invention further teaches textile coating formulations comprising these compositions, a process for applying them on textile fabrics, and the flame retarded fabrics coated by these compositions and formulations.
