Abstract
The present invention provides a composite resin composition capable of forming a film in which a cellulose nanofiber is dispersed uniformly in the resin. The present invention provides a composite resin composition containing an aqueous dispersion medium, a resin particle emulsified in the aqueous dispersion medium, and a cellulose nanofiber dispersed in the aqueous dispersion medium, wherein the resin particle contains at least one selected from the group consisting of a (meth)acrylic resin particle, a styrene-based resin particle, and a (meth)acrylonitrile-based resin particle, and when a sample obtained in such a way that a liquid obtained by diluting the composite resin composition with water in an amount that allows a non-volatile content of the composite resin composition to fall within a range of 0.01 to 0.1% by mass is dropped onto a base material for measurement and is dried is observed with an atomic force microscope, a structure such that the cellulose nanofiber is dispersed, and the resin particles cling in the form of particles to the cellulose nanofiber is observed.
