【発明の名称】ウレタン樹脂を含有する磁気記録媒体用結合剤
Document Type and Number:
Japanese Patent JP2802389
Kind Code:
B2
Abstract:
The sulfobetaine-containing resin has much improved affinity for magnetic powders. Therefore, by using the same as a binder, it becomes possible to attain good dispersion of magnetic powders superfine in particle size and/or large in amount of magnetization. The binder can be used advantageously in the manufacture of magnetic recording media, such as magnetic tapes and magnetic disks.
