| titleOfInvention | Polishing liquid composition for magnetic disk substrate |
| abstract | A polishing composition for a magnetic disk substrate capable of reducing surface roughness and scratches without impairing productivity, and a method for producing a magnetic disk substrate using the same. The method includes silica particles, at least one selected from the group consisting of a polymer having an ionic hydrophilic group and a weight average molecular weight of 100,000 or less, cumenesulfonic acid, and salts thereof, and water. The particle size (R (nm)) vs. cumulative volume frequency (V (%)) graph of the silica particles is a formula (1) with a particle size of 40 to 70 nm: V ≧ R + 30, and a formula (2) with a particle size of 10 to 20 nm: V ≦ 3 × R + 10 and 40 to 45 nm satisfying the formula (3): V ≧ R + 50, and further dividing the area of a circle whose diameter is the maximum diameter of the silica particles by the projected area of the silica particles is 100. A polishing composition for a magnetic disk substrate, wherein the average value of the multiplied values is in the range of 100 to 140. [Selection figure] None |
