Abstract
The present invention provides a method of producing dye-containing thermosetting resin particles, the method including: dispersing seed particles formed from a thermosetting resin in a dispersion medium; and polymerizing a monomer for thermosetting resin synthesis in the thus obtained dispersion in the presence of a dye and an acid catalyst. By the method of producing dye-containing thermosetting resin particles according to the present invention, dye-containing thermosetting resin particles whose particle size variation coefficient is small at, for example, 8% or less, can be produced without performing a post-treatment such as centrifugation. Therefore, when immunological observation is performed by a fluorescent labeling method using fluorescent dye-containing resin particles produced by the method of producing dye-containing thermosetting resin particles according to the present invention, a high bright spot detection accuracy can be attained.
