  • METHOD FOR PRODUCING POROUS SILICA PARTICLE, RESIN COMPOSITION FOR ANTIREFLECTION COATING, AND ARTICLE AND ANTIREFLECTION FILM HAVING ANTIREFLECTION COATING
    Publication number: 20140011954
    Abstract: An object of the present invention is to provide a method for producing porous silica particles having a small particle diameter in high yield relative to a volume of a reaction solution. In order to achieve the object, the present invention provides a method for producing porous silica particles having pores on the surfaces thereof, the method including a step of adding a mixed solution (solution A) containing tetraalkoxysilane, alkylamine, and alcohol to a mixed solution (solution B) containing ammonia, alcohol, and water and performing a hydrolysis and condensation reaction of the tetraalkoxysilane to produce silica particles, and a step of removing the alkylamine from the silica particles.
