摘要：
A novel black coloring material is obtained by treating a chitosan with a dyestuff of the lithospermum root. If a water-insoluble chitosan is used as the chitosan, a finely divided black coloring material is obtained, and if a gelatinous chitosan salt is used as the chitosan, a gelatinous black coloring material is obtained. If a water-soluble chitosan, chitosan oligosaccharide or D-glucosamine, or a salt thereof is used as the chitosan, a liquid black coloring material is obtained. If a powdery polymeric substance is treated with such a black coloring material, a polymer-based black coloring material is obtained, and if a fiber is dyed with such a black coloring material, the fiber is dyed to a black color having a low lightness.
