Abstract:
Disclosed herein is a polishing composition comprising a pH of 6 or less, sulfonic acid-modified colloidal silica obtained by immobilizing sulfonic acid on surfaces of silica particles, and water, wherein the sulfonic acid-modified colloidal silica is derived from sulfonic acid-modified aqueous anionic silica sol produced by a production method comprising: a first reaction step of obtaining a reactant by heating raw colloidal silica having a number distribution ratio of 10% or less of microparticles having a particle diameter of 40% or less relative to a volume average particle diameter based on Heywood diameter (equivalent circle diameter) as determined by image analysis using a scanning electron microscope in the presence of a silane coupling agent having a functional group chemically convertible to a sulfonic acid group; and a second reaction step of converting the functional group to a sulfonic acid group by treating the reactant.

Claim (Index 4):
The method of  claim 3 , wherein the treatment is an oxidation treatment using hydrogen peroxide.
