Zusammenfassung: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. Esta invencion se refiere a un polimero en emulsion acuoso que se usa como agente dispersante de pigmento que comprende como unidades copolimerizadas los siguientes monomeros: (A) un monomero etilenicamente insaturado que contiene al menos un grupo amino; (B) un monomero etilenicamente insaturado que no contiene grupo amino; (C) opcionalmente un hidroxi- o alcoxialquil (met) acrilato de la formula CH2=CH(R1)-COO-CtH2t-OR2 en donde R1 es hidrogeno o metilo y R2 es hidrogeno o alquilo C1-C6 y t es un numero entero de 2, 3, 4, 5 o 6; (D) un (poli)alquilenglicolmono(met)acrilato de la formula CH2=CH(R1)-COO-CmH2mO)n-OR2 en donde R1 es hidrogeno o metilo y R2 es hidrogeno o alquilo C1-C6 y me es un numero entero de 2 o 3 y n es un numero entero de 2 a 20.
