Dispersion (A), in an organic, non-aqueous and non-silicone medium (B), of particles (P) that consist of at least one acrylic polymer (I) that comprises a skeleton insoluble in (B) and a part, soluble in (B), consisting of sidechains, bonded covalently to the skeleton. Dispersion (A), in an organic, non-aqueous and non-silicone medium (B), of particles (P) that consist of at least one acrylic polymer (I) that comprises a skeleton insoluble in (B) and a part, soluble in (B), consisting of sidechains, bonded covalently to the skeleton. (B) is obtained by radical polymerization of an acrylic monomer (M1), forming the insoluble skeleton, and at least one carbon-based macromonomer (M2) that includes an end group that reacts during polymerization to form the sidechains. M2 has molecular weight at least 200 and makes up 1-18 wt.% of the polymer.
