Abstract:
Provided is a hexavalent chromium treatment agent capable of penetrating inside of a leather and capable of reducing not only hexavalent chromium present in the vicinity of the surface of the leather but also hexavalent chromium present inside the leather into trivalent chromium. The hexavalent chromium treatment agent of the present invention comprises a hexavalent chromium-reducing compound capable of reducing hexavalent chromium into trivalent chromium, a nonionic surfactant, and an aqueous solvent. The hexavalent chromium-reducing compound preferably comprises an organic compound (A) that has a specific structure capable of acting to reduce hexavalent chromium into trivalent chromium, that has a hydroxyphenyl group, and that has no aldehyde groups and no carboxyl groups.

Claim (Index 23):
The hexavalent chromium treatment agent according to  claim 15 , wherein the hexavalent chromium-reducing compound is at least one selected from a compound (A-i) represented by the following formula (A-i) and a tannin (A-ii): wherein n represents 0, 1, or 2, R 11  to R 18  each independently represent a hydrogen atom, a hydroxy group, a C 1  to C 4  alkyl group, a C 1  to C 4  alkoxy group, or a group represented by the following formula (a-i), when n is 0, at least one of R 11  to R 14 , R 16  and R 17  is a hydroxy group, when n is 1 or 2, at least one of R 11  to R 18  is a hydroxy group, when n is 2, a plurality of R 15  may be the same or different, and a plurality of R 18  may be the same or different, R 16  and R 17  may be linked together to form a five-membered ring or a six-membered ring, and the ring may have a C 1  to C 16  alkyl group as a substituent: wherein R 19  represents a C 1  to C 4  alkyl group.
