Abstract
Provided are novel compounds of indigo-derivatives as irreversible color changeable dyes. Also provided are methods for the use of various indigo-derivatives for irreversibly color changeable dyes for textile materials and to novel compounds. Also provided is a process for dyeing textile materials, especially denim, with indigo-irreversible color changeable dyes and for textiles and garment articles made by the dyeing process for textile materials.
Claims19
A process for dyeing textile materials, said process comprising applying an indigo-derivative of formula (I)
- wherein
- R1, R2, R3 and R4 each represent a hydrogen atom or a halogen atom, and
- R5 and R6 each represent a hydrogen atom or a tert-butoxycarbonyl group, provided that R5 and R6 are not both hydrogen, onto a textile material.
An indigo-derivative of formula (I)
- wherein each of said R1, R2, R3 and R4 comprises a halogen atom.
Indigo-derivatives of formula (I)
- wherein each of said R1, R2, R3 , R3 and R4 comprises a hydrogen atom, one of said R5 and said R6 is a hydrogen atom and the other of said R5 and said R6 comprises a tert-butoxycarbonyl group.
