摘要:
PROBLEM TO BE SOLVED: To provide a polishing composition that is used for the purpose of polishing substrates, the polishing composition being capable of realizing both improvement of storage stability in an alkaline pH and improvement of polishing speed when polishing the substrates.SOLUTION: A polishing composition is provided for the purpose of being used for polishing substrates, the polishing composition comprising: abrasive grains; an alkaline compound; and water. The abrasive grains carry an anionic functional group, and the pH of the polishing composition is 7.0 or more. The abrasive grains preferably have a surface zeta potential of -20 mV or less, and the content of the alkaline compound is preferably between 0.01 to 5.0 wt.%.
