Abstract:
1. A floor polishing composition, comprising: a film-formable organic resin material as the main component, and scaly particles, wherein said scaly particles are silica corresponding to layered polysilicic acid, wherein said layered polysilicic acid has layered particle structures that present independently from each other, wherein said layered polysilicic acid comprises foliar silica secondary particles that are present discretely from each other, wherein a plurality of flaky primary particles of scaly silica are overlaid one on another and aligned face-to-face in parallel with one another, and wherein the foliar silica secondary particles are obtained by disintegrating an aqueous slurry of tertiary agglomerated particles of silica by means of a mechanical high speed stirring system employing a disintegrating medium.
