The present invention concerns a novel method of flame-proofing flammable material which comprises treating said material with a compound of the formula: ##EQU1## WHEREIN N IS 1 OR 2, AND R, when n is 1, is a radical of the formula ##EQU2## wherein R.sub.1 and R.sub.2 are substituents e.g. alkyl, or R.sub.1 and R.sub.2, together with the nitrogen atom, form a heterocyclic ring or R, when n is 2, is a radical of the formula ##EQU3## wherein R.sub.1 and R.sub.4 are substituents e.g. alkyl and R.sub.3 is a hydrocarbon bridge e.g. alkylene, or R.sub.1, R.sub.2 and R.sub.4, together with the nitrogen atoms to which they are bound, form a heterocyclic ring, or a group of the formula ##SPC1## Wherein m is 1 to 5, and novel compounds (i.e. when n is 2) useful as flame-proofing agents.
