Abstract
Reaction products containing at least two amidophosphate radicals are disclosed. They have been produced from (1) an amidophosphate of the formula ##STR1## wherein R.sub.1 is lower alkyl or both R.sub.1 's together are lower alkylene, (2) formaldehyde, (3) optionally an aliphatic diol with 2 to 6 carbon atoms, (4) optionally a lower alkanol. If a diol according to (3) has been used, R.sub.1 in the amidophosphate according to (1) can also be lower alkenyl or halogenoalkyl. The disclosed reaction products are suitable for flameproofing organic fibre materials, especially cellulosic textiles.
