ALKOXYLATED POLYALKYLENE IMINE HAVING ANIONIC GROUP,PIGMENT CONTAINING THE POLYALKYLENE IMINE, METHOD FOR PRODUCING THE PIGMENT AND APPLICATION OF THE PIGMENT

摘要

PROBLEM TO BE SOLVED: To obtain a pigment dispersant in which a correspondent pigment preparation has high solvent stability and especially a low agglomeration tendency combined with good print starting capability.;SOLUTION: The pigment dispersant is a polyalkylene polyimine having alkoxy units and anionic groups, especially the anionic group selected from the group consisting of COO^-, SO₃^-, PO₃^2- and P(OR)O₂^- [wherein R expresses H or an alkyl which may be substituted, a cycloalkyl or an aryl].;COPYRIGHT: (C)2005,JPO&NCIPI
