Abstract
Composite resin particles each comprising a particulate crosslinked polymer to which a number of substantially linear, metal-containing polymer chains are chemically bonded. The invention also provide methods for the preparation of said composite resin particles. The present composite resin particles have self-film forming properties, can give a stable dispersion in an organic solvent or a resinous varnish and are specifically useful in paint industries. The particles are further characterized by having the desired properties of the metal element contained therein, as, for example, self-catalytic function in crosslinking, excellent biological activities and the like.
