This invention relates to an aqueous emulsion polymer used as pigment dispersing agent comprising as copolymerized units the following monomers (A) an ethylenically unsaturated monomer containing at least one amino group; (B) an ethylenically unsaturated monomer containing no amino group; (C) optionally a hydroxy- or alkoxyalkyl(meth)acrylate of the formula CH2 CH(R1)-COO-CtH2t-OR2 wherein R1 is hydrogen or methyl and R2 is hydrogen or C1-C6alkyl and t is an integer of 2, 3, 4, 5 or 6; (D) a (poly)alkyleneglycolmono(meth)acrylate of the formula CH2 CH(R1)-COO-(CmH2mO)n-OR2 wherein R1 is hydrogen or methyl and R2 is hydrogen or C1-C6alkyl and m is an integer of 2 or 3 and n is an integer of 2 to 20.
