CROSSLINKED SPHERICAL FINE PARTICLES AND PROCESS FOR PRODUCING THE SAME; COATING COMPOSITION AND PEELABLE PRESSURE-SENSITIVE ADHESIVE CONTAINING SAID CROSSLINKED SPHERICLE FINE PARTICLES; AND ARTICLE CONTAINING THEM IN THE FORM OF LAMINAR COMPOSITE

摘要

This invention discloses a cross-linked spherical particulate having good toughness and elasticity and excellent chemical properties and a method of producing said particulate by polymerizing a dispersion of a radical-polymerizable component (M) containing a radical-polymerizable vinylic compound (V) prepared by the reaction of a specified polyol (a), an isocyanate compound (b), and a radical-polymerizable vinyl monomer (c) having an active hydrogen group. Also disclosed are a coating composition produced from said particulate, a filmy or sheetlike article and an adhesive filmy or sheetlike article produced from said composition, and a releasable pressure-sensitive adhesive and an article thereof produced from said particulate.
