ABSTRACT:
The invention relates to an aqueous pigment preparation containing an organic and/or inorganic pigment dispersed in an acrylate resin solution and a dispersion agent. The preparation is characterized in that the acrylate resin is a copolymer consisting essentially of between 50 and 80 mol % of monoalkenyl aromatic compounds and between 20 and 50 mol % of acrylates, and has an average molar mass Mvof between 1,000 and 50,000 g/mol, and in that the dispersion agent is a compound of formula (I): R—O—(CH2-CH2—O)m—CH2—COOM, wherein R is a C10-C20alkyl radical or a C10-C20alkenyl radical, m is a number between 1 and 15, and M is a monovalent cation.
