    摘要: An object of the invention is to provide a heat-resistant hexavalent chromium removal agent, which is capable of remaining in a leather or leather article for a long period of time and stably detoxifying hexavalent chromium over the long term even when a leather or leather article contains hexavalent chromium, and a leather or leather article, in which the hexavalent chromium content is less than 3 ppm. The leather or leather article of the present invention contains at least: an organic compound (A) having a structure shown in chemical formula (1) and hydroxyphenyl but not aldehyde and carboxyl, which organic compound has a property to reduce hexavalent chromium to trivalent chromium; and trivalent chromium, and the hexavalent chromium content determined in accordance with ISO 17075: 2008-02 is less than 3 ppm.
