资源简介：
To provide fine cellulose fiber， the dispersion of which has very high transparency and viscosity， and a method for producing the fine cellulose fiber. In the cellulose fiber， a part of hydroxy groups of cellulose fiber is substituted with a predetermined functional group to introduce an ester of phosphorus-oxo acid， and substituted with a carbamate group to introduce a carbamate. The method for producing fine cellulose fiber includes adding an additive (A) and an additive (B) including at least one of urea and a urea derivative to cellulose fiber， heating the mixture at 100 to 210°C， washing the mixture， and then fibrillating the mixture， the additive (B) being added in an amount of 0.01 to 100 mol based on 1 mol of the additive (A).
