Patent ID: 8173700

Claim:
A substituted allophanate salt consisting of a cation corresponding to formula I wherein n =1, 2, 3, 4, 5 or 6; Q represents N or P; R 1 , R 2 and R 3 each independently denote a linear or branched C 1-5 -alkyl group; or two of R 1 , R 2 and R 3 together with the atom Q to which they are bound form a 4-, 5-, 6- or 7-membered, saturated or unsaturated, unsubstituted or mono- or polysubstituted heterocyclic ring, optionally containing one or more further heteroatoms as ring members, and the remaining group R 1 , R 2 or R 3 has the meaning given above; and R 4 denotes: a linear or branched, saturated or unsaturated aliphatic group, which may be unsubstituted or mono- or polysubstituted, and which optionally may contain one or more heteroatoms as units of the chain; an unsaturated or saturated cycloaliphatic group, which may be unsubstituted or mono- or polysubstituted, and which optionally may contain one or more heteroatoms as ring members, and which optionally may be joined via a linear or branched alkylene group; an aryl or heteroaryl group, which may be unsubstituted or mono- or polysubstituted, and which optionally may be joined via a linear or branched alkylene group; or a group —(CH 2 ) q -A r —(CH 2 ) s —B—(CH 2 ) t -C u —R 5 , wherein q, s and t each independently denote 0, 1, 2, 3, 4, 5 or 6; r and u each independently denote 0 or 1; A and C each independently denote O, S or NH; B represents: a linear or branched alkylene, alkenyl or alkinyl group, unsubstituted or mono- or polyssubstituted; an unsaturated or saturated cycloaliphatic group, unsubstituted or mono- or polysubstituted, optionally containing one or more heteroatoms as ring members; or an aryl or heteroaryl group, unsubstituted or mono- or polysubstituted; and R 5 represents a linear or branched, saturated or unsaturated aliphatic group, unsubstituted or mono- or polysubstituted; and an anion.
