<p>A process for producing an aqueous cellulose derivative dispersion, characterized by dissolving a carboxylated cellulose derivative in an organic solvent to obtain a solution, agitating the solution together with water in the presence of 1 to 65 mol% alkali based on the carboxyl groups to obtain a dispersion, removing the organic solvent from the dispersion to obtain a raw aqueous dispersion, and removing part or all of the alkali used from the aqueous dispersion.</p> |
