Abstract: A method for producing a liquid dispersion of composite resin particles includes polymerizing a styrene compound and an extra vinyl monomer together to give a styrene resin; polymerizing a (meth)acrylate compound in the presence of the styrene resin to give intermediate resin particles A, which are resin particles containing the styrene resin and a (meth)acrylate resin; polymerizing a styrene compound and an extra vinyl monomer in the presence of intermediate resin particles A to give liquid dispersion B, which is a liquid dispersion containing intermediate resin particles B; and adding a polymerization initiator to liquid dispersion B to give a liquid dispersion containing composite resin particles. In the composite resin particles as a whole, the ratio by mass between the styrene and (meth)acrylate resins is between 80:20 and 20:80. There is a difference of 30° C. or more between the lowest and highest glass transition temperatures of the composite resin particles.
