摘要： Resinous particles carried on the respective grain surface with a metal compound through a metal ester bonding, and preparation methods thereof, said metal compound having a biological activity, above all, against harmful livings, and said preparation method comprising forming a metal ester bonding by reacting a metal compound with resin particles having a mean grain diameter of 0.01 to 250.mu. and bearing organic acid group(s) in the form of free acid or salt on the respective grain surface thereof. Said resinous particles are characterized by having metal compound(s) only on the respective grain surface, and therefore, the amounts of metal compound required for the preparation of hydrolyzable resinous particles are greatly reduced as compared with those of the heretofore proposed metal containing resinous particles.

摘要： Composite resin particles each comprising a particulate crosslinked polymer to which a number of substantiary 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 the 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, as, for example, self-catalytic function in crosslinking, excellent biological activities and the like.

摘要： As a curing catalyst of epoxy resins, superacid salts of an N, N'-di- or N, N', N'-trisubstituted urea are disclosed. The urea component is produced by reacting an organic isocyanate and a primary or secondary amine at least one of which is monofunctional. The catalyst is soluble in conventional organic solvents, well compatible with the epoxy resin and catalizes the cationic polymerization reaction of epoxy resins at room temperature.
