    • To provide a composition capable of minimizing the average surface roughness (Ra) after texturing of the ground layer of an aluminum magnetic disc or the surface of a glass magnetic disc, forming fine texturing streaks, removing “polishing marks” or “polishing scratches” ascribable to the substrate polishing step and which are present on the ground layer or on the surface, and ensuring a high processing rate. A composition for a texturing process, which is used for texturing a ground layer of an aluminum magnetic disc or a surface of a glass magnetic disc, the composition comprising (A) nano-diamond particles having a specific surface area of 150 m2/g or more, (B) a fatty acid having from 10 to 22 carbon atoms or a fatty acid salt, and (C) an organic amine compound.
    • 为了提供能够使铝磁盘的接地层或玻璃磁盘的表面纹理化后的平均表面粗糙度(Ra)最小化的组合物,形成细微的纹理条纹,除去归因的“抛光痕迹”或“抛光划痕” 到基板研磨步骤,并且其存在于接地层或表面上,并且确保高处理速率。 用于纹理化处理的组合物,其用于纹理化铝磁盘或玻璃磁盘的表面的接地层,所述组合物包含(A)比表面积为150μm的纳米金刚石颗粒, (B)具有10-22个碳原子的脂肪酸或脂肪酸盐,和(C)有机胺化合物。
