Abstract
A cellulose microcapsule having absorbing capacity, consisting of outer semipermeable barrier layer of cellulose and absorbent powders dispersed within inner cellulose gel matrix is prepared by dispersing adsorbent powders in a solution of cellulose dissolved in a solvent which is not adversely affected by the adsorbing capacity of adsorbent powders and capable of dissolving cellulose, then forming the dispersion into droplets and finally precipitating cellulose on the droplets. It is excellent in resistance to chemicals such as acids, alkalis or organic solvents and is useful for various purposes.
