Document Type and Number:
WIPO Patent Application WO/2023/132012
Kind Code:
A1
Abstract:
[Problem] To provide a composition containing fine cellulose fibers in which the CNFs can have improved dispersibility and handleability and a coating material and a thickener which each include the composition containing fine cellulose fibers. [Solution] This composition comprises water, a water-soluble solvent, and sulfonated fine cellulose fibers which are dispersed in a mixture solution composed of the water-soluble solvent and the water and in which some of hydroxyl groups have been replaced with sulfo groups so as to result in an amount of introduced sulfo groups of 0.4-3.0 mmol/g. This composition has a haze of 30% or less when containing the sulfonated fine cellulose fibers in a solid concentration of 0.5 mass%. By using the composition containing fine cellulose fibers for a liquid of interest which has an affinity for the water-soluble solvent, the fine cellulose fibers can be adequately dispersed in the liquid and excellent properties can hence be imparted to the liquid.
