    摘要： The invention relates to an aqueous paint composition comprising a mixture containing: (1) an aqueous paint; (2) a colloidal dispersion of a cerium compound, having a pH of at least 5 and comprising a water-soluble or water-dispersible polymer (i) which is obtained following the polymerisation of at least one monomer (I) corresponding to (I) an ethylenically-unsaturated, aliphatic, cyclic or aromatic, linear or branched monocarboxylic or polycarboxylic anhydride or acid and, optionally, a monomer corresponding to (II) a polyoxyalkylene ester of an ethylenically-unsatured carboxylic acid; and (3) a base. The invention also relates to paints and varnishes containing said composition.

    摘要： The present invention is directed to controlling aggregation of rare earth particles using block copolymers and rare earth base particles. More particularly, invention is also directed to forming stable complexes of rare earth aggregates by complexing rare earth base particles with oppositely charged-neutral di-block copolymers. Even more particularly, invention is also directed to forming stable complexes of rare earth nanoparticles by complexing rare earth ultrafine particles with oppositely charged-neutral di-block copolymers.
