A B S T R A C T Addition compounds suitable as dispersing agents, obtain- able by the reaction of polyisocyanates having an average functionality of from 2.5 to 6 with monohydroxyl compounds, reaction of the resulting reaction product with compounds of the formula II G-(E)n II wherein E stands for -OH, -NH2 and/or -NHR (wherein R represents an alkyl group with 1 to 4 carbon atoms) and n stands for 2 or 3, and G represents an aliphatic, cycloaliphatic and/or aromatic group, and further reaction of the reaction product thus obtained with compounds of the formula III Z-Q III wherein Q stands for -OH, -NH2, -NHR (wherein R stands for an alkyl group having 1 to 4 carbon atoms) or -SH, and Z denotes a group having at least one basic group containing nitrogen. The invention also relates to process- es for the preparation of these addition compounds, their use, and pulverulent or fibrous solids which are coated with these dispersing agents and are to be incorporated in liquid systems.
