Beschreibung
Zusammenfassung:	The present invention is directed to intumescent compositions, which may be foamed, obtained by reacting: (1) polyisocyanates, (2) phosphorus-containing condensation products having at least one hydroxyl group and obtained by condensing (i) primary or secondary aliphatic, cycloaliphatic, aromatic, araliphatic or heterocyclic monoamines and/or polyamines, which mono- and polyamines may contain OH groups, (ii) carbonyl compounds, and (iii) dialkyl phosphites, (3) aromatic hydroxy carboxylic acids or salts thereof, and (4) optionally, water and/or additional organic compounds containing isocyanate-reactive hydrogen atoms.
