Abstract
Abstract A dyestuff composition for the dyeing or printing of natural or regenerated cellulose fiber materials, consisting of 20 to 70 percent by weight of C.I. Reactive Blue 19 (sodium salt), anthraquinone-2-sulfonic acid (sodium salt), a condensation product of naphthalene-sulfonic acid with formaldehyde (sodium salt), a condensed phosphate (sodium salt), preferably sodiumhexametaphosphate or penta-sodiumtriphosphate, and a dust preventing agent.

Claim 3
Dependent Claim
17 words
A dyestuff composition as claimed in claim 1, wherein the dust-preventing agent is a mineral oil emulsion.
Claim 4
Dependent Claim
16 words
A dyestuff composition as claimed in claim 1, which additionally contains urea, dextrin or cane sugar.
Claim 5
Dependent Claim
18 words
A dyestuff composition as claimed in claim 1, which has been obtained by mixing or grinding the ingredients.
Claim 6
Dependent Claim
22 words

Claim 7
Dependent Claim
71 words
A dyestuff composition as claimed in claim 1, which contains, as additives, 5 percent by weight of anthraquinone-2-sulfonic acid sodium salt, 3 percent by weight of a condensed phosphate sodium salt selected from the group consisting of sodiumhexametaphosphate and penta-sodiumtriphosphate, 3 percent by weight of a mineral oil emulsion, 3 percent by weight of urea, the balance being a sodium salt of the condensation product of naphthalene sulfonic acid with formaldehyde.
