Abstract
The present invention provides a method for manufacturing a cellulose nanofiber, characterized by comprising the step of fibrillating cellulose in a polyester based resin, preferably in a polyester based resin having an ester group concentration of 6.0 mmol/g or more and a cellulose nanofiber produced by the manufacturing method concerned. In addition, the present invention provides a masterbatch composition containing the cellulose nanofibers and the polyester based resin. Furthermore, the present invention provides a resin composition containing the masterbatch composition and a diluent resin and a processed product thereof.
