Hexavalent chromium treatment agent and leather or leather products using the same |
| abstract |
[Problem] To provide a hexavalent chromium treatment agent that can penetrate into the leather, not only the hexavalent chromium near the leather surface, but also the inner hexavalent chromium can be reduced to trivalent chromium. [Solution] The hexavalent chromium treatment agent of the present invention includes a hexavalent chromium reducing compound capable of reducing hexavalent chromium to trivalent chromium, a nonionic surfactant, and an aqueous solvent. As a hexavalent chromium reducing compound, it is preferable to contain the organic compound (A) which has a specific structure and a hydroxyphenyl group and has a reducibility which acts on hexavalent chromium and reduces to trivalent, and does not have an aldehyde group and a carboxyl group. |
