摘要： PROBLEM TO BE SOLVED: To obtain silica fine particles having high hardness and strength as a whole which can function as a spacer for a long time when the particles are used as a spacer for a liquid crystal display device by applying a vinyl silane coupling agent on the surface of calcined silica fine particles and then forming a thermoplastic resin coating film having a single layer or multilayer structure thereon. SOLUTION: The resin-coated silica fine particles are produced by applying a silane coupling agent having vinyl groups on the surface of calcined silica fine particles and then forming a thermoplastic resin film having a single layer or multilayer structure thereon. The production method of the resin-coated silica fine particles includes the following processes (A) and (B). In the process (A), calcined silica fine particles are subjected to surface treatment with a silane coupling agent having vinyl groups so as to introduce vinyl groups to the surface of silica fine particles. In the process (B), unifunctional vinyl monomers are dispersed and polymerized in a polar solvent in the presence of a dispersion stabilizer, radical polymn. initiator and chain-moving agent to form a thermoplastic resin coating film on the surface of silica fine particles after the surface treatment.

摘要： PURPOSE: To obtain spherical particles with insulating films having dense and thick insulating films which are suitable as a spacer for a liquid crystal display device. CONSTITUTION: Spherical particles of metal oxide are dispersed in an alcohol solvent essentially comprising medium alcohol to obtain a dispersion liquid of particles. An alkali soln. is added to the dispersion liquid to activate the surface of particles to form a titanium oxide film on the particle surface. Thus, spherical particles with titanium oxide films (A) are obtd. Then the particles (A) are dispersed in an alcohol solvent essentially comprising medium alcohol to obtain a dispersion liquid, to which an alkali soln. is added to activate the surface of the titanium oxide film. Then silicon alkoxide or its partial hydrolyzed material (C) is added to perform hydrolysis, dehydration and condensation to obtain spherical particles with titanium oxide films and silica films (B). The obtd. particles (B) are separated from the dispersion liquid (process a). The particles (B) are dispersed in a lower alcohol solvent, to which quaternary ammonium salt as an electrolyte is added and dissolved. Then an alkali soln. and (C) are added to perform hydrolysis, dehydration and condensation to form further silica films, on the particles (B) (process b).
