Abstract
A method of producing hollow silica microparticles that suppress whitening of a transparent coating film and show excellent abrasion resistance and adhesiveness. The method includes preparation of an organosol in which hollow silica microparticles are dispersed with the silica concentration of 1 to 70 W % and addition of a silane compound and an alkali catalyst to the organosol at a temperature in the range from 30° C. to 300° C. to react the silane compound to the hollow silica microparticles under the condition where a quantity of water against the added silica (the hollow silica microparticles) is in the range from 0.1 to 50 W %.
