Abstract
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 1 is lower alkyl or both R 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 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.
