  A binder for coating materials containing dispersed inorganic powder comprises a polyurethane resin containing (a) 2.2 to 7.0 terminal epoxy groups in one molecule in average and (b) 0.1 to 5.0 % by weight as SO₃⁻ of a sulfonic acid salt group, 0.05 to 3.0 % by weight as COO⁻ of a carboxylic acid salt group, or 0.02 to 1.0 % by weight as N⁺ of a quaternary ammonium salt group in the molecule, and having a number-average molecular weight of 2,000 to 10,000. A coating material containing dispersed inorganic powder and a magnetic recording medium both use this binder. In a recording medium comprising a magnetic layer placed on a non-magnetic substrate, the magnetic layer comprises polyurethane resin (A) as a binder, vinyl chloride polymer (B) containing 0.1 to 20 % by weight of epoxy group and having an average degree of polymerization of 100 to 500, as another binder, (C) an alicylic acid anhydride as a crosslinking agent, and (E) a tertiary amine as a catalyst, and at least one of the binders is crosslinked between the epoxy groups therein by the reaction in which components (C) and (E) take part. The coating material containing fine inorganic powder dispersed with stability and having a low viscosity can be obtained by using, as the binder, the polyurethane resin having terminal epoxy groups and one of a sulfonic acid salt group, a carboxylic acid salt group, and a quaternary ammonium salt group. The magnetic recording material prepared by using magnetic powder as the inorganic powder and crosslinking the binder is excellent in dispersion of the magnetic powder and smoothness of the surface. Therefore, the magnetic recording medium is excellent in magnetic properties, durability, and running properties.

  一种用于含有分散无机粉末的涂层材料的粘结剂包括一种聚氨酯树脂，该树脂含有 (a) 一个分子中平均 2.2 至 7.0 个末端环氧基团和 (b) 以重量计 0.1 至 5.0 % 的磺酸盐基 SO₃-、0.05至3.0%(以重量计)的羧酸盐基COO-，或0.02至1.0%(以重量计)的季铵盐基N⁺，其平均分子量为2,000至10,000。含有分散无机粉末的涂层材料和磁性记录介质都使用这种粘合剂。在一种记录介质中，包括置于非磁性基底上的磁性层，磁性层包括作为粘合剂的聚氨酯树脂 (A)、氯乙烯聚合物 (B)、含有 0.(C) 作为交联剂的水杨酸酐，和 (E) 作为催化剂的叔胺，并且至少有一种粘合剂通过组分 (C) 和 (E) 参与的反应在其中的环氧基团之间交联。使用具有末端环氧基团和磺酸盐基团、羧酸盐基团和季铵盐基团之一的聚氨酯树脂作为粘合剂，可以获得含有分散稳定且粘度低的细小无机粉末的涂层材料。使用磁性粉末作为无机粉末并交联粘合剂制备的磁记录材料在磁性粉末的分散性和表面光滑度方面都非常出色。因此，磁记录介质在磁性能、耐用性和运行性能方面都非常出色。
