摘要

1. New sulphur dyestuffs which can be prepared in accordance with processes which are in themselves known by sulphurising new leuco-indophenols or leuco-indamines of the formula I see diagramm : EP0037975,P11,F5 wherein R**2 denotes hydrogen or alkyl having 1 to 8 C atoms, R**3 and R**4 independently of one another denote hydrogen, halogen or alkyl having 1 to 4 C atoms, or conjointly form a structural element of the formula Ia-d see diagramm : EP0037975,P12,F1 see diagramm : EP0037975,P12,F2 see diagramm : EP0037975,P12,F3 see diagramm : EP0037975,P12,F4 R**5 denotes alkoxy having 1 to 4 C atoms, amino, -NHR**6 , -N(R**6 )2 and see diagramm : EP0037975,P12,F5 and also denotes hydrogen, if R**3 and R**4 conjointly form a structural element of the formula Ia-d, and also denotes hydroxyl if R**3 and/or R**4 are not hydrogen, R**6 denotes alkyl having 1 to 4 C atoms, it being possible for the alkyl radicals which are represented by R**2 , R**3 , R**4 and R**6 to be substituted by a halogen atom, and X denotes -S-, -SO2 -, -NH- or a direct bond.
