The present disclosure relates to a solid pigment preparation, comprising at least one pigment in an aqueous solution comprising an amine-functional acrylic block copolymer and an amine-functional polymeric dispersant comprising a polyoxyalkylene moiety, as well as a process for producing the solid pigment preparations and their use in various coloring applications. The solid pigment preparations are particularly universally dispersible in both water- and solvent-based systems. Corresponding dispersions are accordingly also within the scope of the present disclosure. La présente invention concerne une préparation de pigment solide, comprenant au moins un pigment dans une solution aqueuse comprenant un copolymère séquencé acrylique à fonctionnalité amine et un dispersant polymère à fonctionnalité amine comprenant un fragment polyoxyalkylène, ainsi qu'un procédé de production des préparations de pigment solide et leur utilisation dans diverses applications de coloration. Les préparations de pigment solide sont particulièrement universellement dispersibles dans les systèmes à la fois à base d'eau et à base de solvant. Des dispersions correspondantes relèvent de manière correspondante du champ d'application de la présente invention.
