Abstract

The present invention provides a method for producing cellulose nanofibers, the method including fibrillating cellulose in a modified epoxy resin (A) having a hydroxyl value of 100 mgKOH/g or more. Also, the present invention provides cellulose nanofibers produced by the production method and a master batch containing the cellulose nanofibers and the modified epoxy resin (A). Further, present invention provides a resin composition containing the master batch and a curing agent (D), and provides a molded product produced by molding the resin composition.
