Non-ionic anthraquinone, quinophthalone or azo dye composition, e.g. as inkjet or sublimation transfer printing ink, comprises naphthalene sulfonic acid/formaldehyde condensate of high molecular weight as dispersant

摘要

Dye composition comprises 0.1-30 wt.% non-ionic anthraquinone, quinophthalone or azo dye(s), 0.1-20 wt.% of a dispersant comprising a naphthalene sulfonic acid/formaldehyde condensate (I) with an average molecular weight of at least 11000, 0.1-90 wt.% mono- or polyhydric alcohol(s), 0-5 wt.% additives and optionally water to 100 wt.%. Independent claims are also included for: (1) printing of textile substrates by inkjet or sublimation transfer printing using the dye composition; (2) printed textile substrates produced as above.
