The invention relates to comb copolymers, which can be produced from at least one diglycidyl ether (A) of general formula (I), at least one polyether monoamine (B) of the general formula Rt—[OEt]n[OPr]m[OBu]s—NH2, at least one amine (C) of the general formula Z—R1—NH2, and optionally at least one secondary amine (D) that is free of primary amino groups and is of the general formula NHTV, wherein R stands for a residue free of epoxy groups, selected from aliphatic residues, aromatic residues, and araliphatic residues; Rt stands for a residue selected from alkyl residues having 1 to 6 carbon atoms; OEt stands for an ethylene oxide residue, OPr stands for a propylene oxide residue, and OBu stands for a butylene oxide residue; n stands for a number from 0 to 100, m stands for a number from 3 to 50, and s stands for a number from 0 to 20, and n+m+s=3 to 103; R1 stands for an aliphatic, aromatic, or araliphatic hydrocarbon residue having 1 to 12 carbon atoms; Z stands for a residue free of primary and secondary amino groups and having at least one basic nitrogen atom, T and V do not contain any secondary amino groups and stand, independently of each other, for aliphatic residues having 1 to 12 carbon atoms, aromatic residues having 6 to 12 carbon atoms, or araliphatic residues having 7 to 12 carbon atoms, wherein the molar number of the sum of the primary amino groups of the polyether monoamines (B) and primary amino groups of the amines (C) divided by the molar number of the epoxy groups of the diglycidyl ethers (A) equals a value of ⅓ to ¾. The invention further relates to the production of the comb copolymers, dispersions, particulate preparations, wetting agents, and dispersants that contain the comb copolymers, to particles coated with the comb copolymers, and to the use of the comb copolymers as wetting agents and dispersants, in particular for increasing the jetness.
