    摘要: Flameproofed, regenerated cellulose containing as a flameproofing agent a compound of the formula, ##STR1## in which both Y's, are oxygen or sulphur,both R.sub.1 's are cyclohexyl or optionally substituted phenyl, or additionally methyl when Y is sulphur, andboth R.sub.2 's are a radical --NR.sub.3 R.sub.4, whereinR.sub.3 is hydrogen or alkyl andR.sub.4 is alkyl, cyclohexyl or optionally substituted phenyl, orR.sub.3 and R.sub.4 together with the common nitrogen atom form a saturated heterocyclic ring,with the proviso that when Y is oxygen, R.sub.3 is hydrogen and R.sub.1 is optionally substituted phenyl, R.sub.4 is only optionally substituted phenyl.
