Abstract
Abstract Novel chromium complex dyes are disclosed which have the formula ##STR1## wherein S 1 represents a hydrogen or halogen atom, a nitro group, a sulpho group, an alkyl or alkoxy radical, an acylamino or arylazo group, S 2 represents a hydrogen or halogen atom, a nitro group, a sulpho group, an alkyl or alkoxy radical, S 3 represents a hydrogen atom, a nitro group or a halogen atom, P is 1 or 2, R represents a fluorochloropyrimidyl or fluorotriazinyl radical, a chloroacetyl, bromoacetyl, α-chloro- or α-bromoacryloyl radical or an α,β-dichloro- or α,β-dibromopropionyl radical, and K.sup.⊕ represents a cation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
44 words
A process for dyeing or printing a substrate of cellulose or shrinkproofed wool, comprising the step of applying to the substrate a chromium complex dye of the formula ##STR13## wherein the ring a is substituted by 4- or 5-nitro, and M is a cation.
Claim 2
Dependent Claim
44 words
A process for dyeing or printing a substrate of cellulose or shrinkproofed wool, comprising the step of applying to the substrate a chromium complex dye of the formula ##STR13## wherein the ring a is substituted by 4- or 5-nitro, and M is a cation.
Claim 3
Dependent Claim
18 words
The process of claim 1, wherein in the chromium complex dye the nitro substituent is in the 4-position.
Claim 4
Dependent Claim
30 words
Cellulose or shrinkproofed wool dyed or printed with a chromium complex dye of the formula ##STR14## wherein the ring a is substituted 4- or 5-nitro, and M is a cation.
Claim 5
Dependent Claim
30 words
Cellulose or shrinkproofed wool dyed or printed with a chromium complex dye of the formula ##STR14## wherein the ring a is substituted 4- or 5-nitro, and M is a cation.
Claim 6
Dependent Claim
23 words
