Abstract
What is provided is a method for producing a composite-particle composition including a first step of obtaining a dispersion liquid of fine fibers; a second step of coating a surface of liquid droplets of a polymerizable monomer or a polymer with the fine fibers in the dispersion liquid to stabilize the liquid droplets as an emulsion; a third step of polymerizing the liquid droplets of the polymerizable monomer or the polymer to obtain composite particles including the polymer coated with the fine fibers; and a fourth step of adsorbing a compound that forms an ionic bond in a pair with an ionic functional group of the fine fibers onto the fine fibers in the surface of the composite particles.
