Abstract
Phosphorus-containing reaction products are provided which are formed from: PA1 A. an amidophosphate of the formula ##STR1## in which R.sub.1 and R.sub.2 each are lower alkyl, halogenoalkyl or alkenyl or R.sub.1 and R.sub.2 together are lower alkylene; PA1 B. a 1,3,5-triazine substituted by at least 2 primary amino groups; PA1 C. formaldehyde and, optionally, PA1 D. a lower alkanol. These phosphorus-containing reaction products are useful as flameproofing agents for cellulose-containing fiber materials.
