摘要

The invention relates to a dispersing agent or salts thereof, comprising the reaction product of: A) one or more polyisocyanates with an average functionality of about 2 to about 5, with B) a compound of the type Y-R-X, wherein Y represents a ring structure with at least one nitrogen atom in the ring, R represents a chain of at least three atoms and X has the meaning O-R<1> or N(R<1>)(R<2>), wherein R<1> is H or a group of the formula R<3>-Z, wherein R<3> represents a chain with at least two atoms and Z represents OH or NH2, and R<2> represents a group of the formula R<3>-Z, which compound is obtainable through reaction of an acrylate compound or an epoxide compound with a cyclic compound which has at least one group of structure ( alpha ) in the ring.
