Title:
AQUEOUS DISPERSION COMPOSITION CONTAINING MICROFIBRILLATED CELLULOSE FIBERS
Document Type and Number:
WIPO Patent Application WO/2023/026882
Kind Code:
A1
Abstract:
The present invention provides an aqueous dispersion composition which contains microfibrillated cellulose fibers having an average fiber diameter of 500 nm or more, and which is characterized in that if this aqueous dispersion composition is adjusted so as to have a solid content concentration of 1% by mass, and is uniformly spread over a horizontal surface and dried thereon, thereby being formed into a sheet, and the intensity XFe derived from iron atoms and the intensity XK derived from potassium atoms are determined by X-ray fluorescence analysis of the thus-obtained sheet, the relational expression XFe/XK ≤ 150 is satisfied.
