Abstract
The invention relates to crosslinked (meth)acrylate-based resin particles having an average particle diameter of 1 to 10 μm, containing monomer components containing a monomer having a carboxyl group and at least one monomer selected from an acrylate and a methacrylate copolymerized therein, the particles having a surface coated with a surfactant having a sulfonic acid group or a sulfonate group, and a process for producing the same.
