Abstract

Procedimiento de obtención de soluciones pigmentadas de esteres o éteres de celulosa caracterizado por comprender las etapas de mezclar un ester o éter de celulosa prácticamente desecado y pulverizado y un pigmento seco en el estado de subdivisión deseado en la solución en una proporción no superior al 12% en peso con respecto al peso del ester o éter de celulosa hasta que el pigmento está prácticamente distribuído de modo uniforme sobre las superficies del ester o éter de celulosa en polvo y de agitar luego la mezcla seca así obtenida con un disolvente para el ester o éter de celulosa hasta que este último se haya disuelto en el disolvente para formar una solución pigmentada.
