CELLULOSE DISPERSION - ASAHI CHEMICAL IND

Title:

CELLULOSE DISPERSION

Document Type and Number:

WIPO Patent Application WO/1999/028350

Kind Code:

A1

Abstract:

A cellulose dispersion comprising a cellulose having a fraction of cellulose I of 0.1 or below and a fraction of cellulose II of 0.4 or below and a dispersion medium, wherein the mean particle diameter of the dispersed cellulose particles is 5 $g(m)m or below; and fine cellulose particles and fine cellulose composite particles having a mean particle diameter of 0.2 to 20 $g(m)m, a major axis (L)/minor axis (D) ratio of 1.2 or below as found under a scanning electron microscope, and a cohesion coefficient of 1.0 to 3.0. The cellulose dispersion is excellent in dispersion stability, transparency and so on, while the fine cellulose particles and fine cellulose composite particles are free from the feeling of roughness and exhibit excellent rollability and high dispersibility.
