摘要： An object of the present invention is to provide a technology of dispersing cellulose readily in a hydrophobic substance such as a resin by treating cellulose being a hydrophilic substance in a system that contains water as a main medium with a polymer dispersant, which has been developed for dispersing a fine and hydrophobic substance such as a pigment, in a simple and efficient manner without conducting surface modification of nanocellulose or other treatments. The object is solved by a process for producing a readily dispersible cellulose composition, the process including dissolving a polymer dispersant having a block copolymer structure having a resin-affinitive segment A and a cellulose-adsorptive segment B in a hydrophilic organic solvent solution, adding a surface active agent to the resultant solution, thereafter adding water to the resultant mixture to prepare an aqueous dispersion treatment agent containing the polymer dispersant, and adding the obtained aqueous dispersion treatment agent to cellulose in a water-containing state or in a dry state, thereby obtaining a readily dispersible cellulose composition. The object is also solved by a process for producing an aqueous dispersion treatment agent for use in the process for producing a readily dispersible cellulose composition, the readily dispersible cellulose composition, and a cellulose-dispersed resin composition using the readily dispersible cellulose composition.
