ABSTRACT OF THE DISCLOSURE Disclosed herein are crosslinked spherical fine particles having good toughness, elastic properties, and chemical properties, and a process for producing the same, said fine particles being obtained by radical polymerization in the suspended state of a component [M] capable of radical polymerization containing a vinyl group-containing compound (V) capable of radical polymerization which is obtained by reaction of (a) a selected polyol, (b) an isocyanate group-containing compound, and (c) an active hydrogen-containing vinyl monomer capable of radical polymerization. Also disclosed herein are the secondary products of the crosslinked spherical fine particles, which include a coating composition and its derivatives (such as filmlike article, sheetlike article, adhesive filmlike article, and adhesive sheetlike article) and a peelable pressure-sensitive adhesive and peelable pressure- sensitive adhesive article.
