Polishing liquid composition for magnetic-disk substrate |
| abstract |
The present invention provides a polishing liquid composition for magnetic-disk substrates which is capable of giving a polished substrate reduced in scratches, nanometer-order projection defects, and surface undulations. The polishing liquid composition for magnetic-disk substrates comprises a copolymer or a salt thereof, an abrasive material, and water, the copolymer having a structural unit derived from a monomer having a solubility in 100 g of 20 DEG C water of 2 g or less and a structural unit that has a sulfo group and having a saturated hydrocarbon chain as the main chain. |
