SE PRESENTA UN PROCESO PARA LA PRODUCCION DE UNA COMPOSICION PARA PIGMENTOS, QUE COMPRENDE LA COMBINACION DE A) UNA DISPERSION DE UNO O MAS COMPONENTES NO POLARES DE UN VEHICULO DE REVESTIMIENTO SUPERFICIAL, O UN ADITIVO NO POLAR PARA LA COMPOSICION DEL PIGMENTO EN UNA SOLUCION ACUOSA DE UNA SAL DE UN ADITIVO PARA PIGMENTOS POLAR, CON B) UNA PASTA ACUOSA DE UN PIGMENTO O UN PRECURSOR DEL MISMO, ANTES, DURANTE O DESPUES DE LA SINTESIS DEL PIGMENTO; POSTERIORMENTE SE AISLA LA COMPOSICION PARA PIGMENTOS ASI OBTENIDA. A process for the production of a pigment composition, comprising combining a) a dispersion of one or more non-polar components of a suiface coating vehicle, or a non-polar additive for the pigment composition in an aqueous solution of a salt of a polar pigment additive, with b) an aqueous slurry of a pigment or a precursor thereof, before, during or after the synthesis of the pigment; and then isolating the pigment composition so obtained.
