Abstract
The present invention provides an amino resin composite particle in which an inorganic compound is fixed (firmly adhered) on a surface of an amino resin particle, for example, an amino resin composite particle, in which a child particle made of the inorganic compound is fixed on a mother particle made of the amino resin particle, and a method of easily and inexpensively producing the amino resin composite particle. After an amino compound such as benzoguanamine is reacted with formaldehyde, so as to prepare a reaction mixture containing an amino resin precursor to be the mother particle, an emulsion of the reaction mixture and an aqueous solution of an emulsifier, and an aqueous dispersion of the inorganic compound, such as silica powder, to be the child particle are mixed with a shear force application, so as to emulsify them to have an emulsion thereof. The emulsion is hardened by adding a catalyst. The thus obtained amino resin composite particle has a firm-adhering ratio of the inorganic compound of 10% or more.
