Pigment compositions

摘要

Pigment preparations (I) containing (a) pigment(s) and (b) alkoxylated polyethyleneimine(s) (PEI) (especially ethoxylated, propoxylated and/or butoxylated PEI) also contain (c) condensation product(s) based on (A) sulfonated aromatics, (B) aldehydes and/or ketones and optionally (C) unsulfonated aromatics, urea and/or urea derivatives. An independent claim is also included for a method for the production of (I) by homogenizing the components in the presence of water, optionally removing large particles (preferably with a membrane or glass filter) and optionally drying.
