Methods of making leucoindigo salt solutions with very low aniline content |
| abstract |
Aqueous leucoindigo solution comprising an aromatic amine in the form of aniline or aniline and N-methylaniline, wherein said leucoindigo is in the form of an alkali metal salt; n wherein the concentration of the aromatic amine is below 40 ppm determined according to ISO 14362-1:2017(E); andn nwherein the concentration of the leucoindigo salt is in a concentration range of from 15 to 45% by weight based on the total weight of the solution, and wherein the solution is stable at a temperature of 23° C.; orn nwherein the concentration of the leucoindigo salt is in a concentration range of from 45 to 65% by weight based on the total weight of the solution, and wherein the solution is stable at a temperature of 60° C. |
