Abstract: A liquid concentrate of pigments of mineral and organic hybrid solid particles of 0.5 to 2 ?m, including a copolymer consisting of: 5 to 40 wt % of anchor sequence(s) consisting of a linear copolymer formed from a first monomer with a basic nitrogenous group added from compound(s) selected from vinylpyridines, and a second monomer of the anchor sequence consists of an ethylene monomer containing an aromatic group, the weight content of the first monomer relative to the second monomer being 40-60 wt %, 25 to 90 wt % of the hydrophobic sequence(s) obtained from a polymer-substituted ethylene macromonomer of which the monomer units contain —COOR10 groups, where R10 is an optionally substituted C1-C10 alkyl, and 5 to 70 wt % of hydrophilic sequence(s) obtained from an ethylene macromonomer substituted by a hydrophilic sequence comprising a polyethylene glycol sequence substituted by a terminal alkoxy group, or connected to a polypropylene glycol sequence.
