The present disclosure pertains to an aqueous inkjet ink containing a pigment as colorant, a polymeric binder, an anionic surfactant and a 1-alkyl-2-pyrrolidone co-solvent. The present disclosure further pertains to an ink set containing this aqueous inkjet ink, as well as to methods of printing with this ink and ink set on a variety of substrates, and particularly hydrophobic substrates and nonporous media.

Inkjet inks and ink sets

The present disclosure pertains to an aqueous pigment dispersion containing a pigment as colorant, a polymeric dispersant and a hydroxyl-substituted amino acid. The present disclosure further pertains to an ink containing an aqueous vehicle and the aqueous pigment dispersion, and ink sets with at least one of the inks containing the pigment dispersion.

Aqueous pigment dispersions and inkjet inks

The present invention pertains to an aqueous inkjet ink set based on disperse dye colorants and, more particularly, to such an inkjet ink set particularly suitable for printing on polyester and polyester blend textiles, such as automotive textile stock, so that the printed fabric is colorfast when exposed to light.

Inkjet ink set

The present invention pertains to a dye-based inkjet ink set and, more particularly, to a dye-based inkjet ink set suitable for printing on polyamide fabric.

The present invention pertains to a dye-based inkjet ink set that includes a red disperse dye and, more particularly, to a dye-based inkjet ink set suitable for printing on polyester and polyester blends fabrics. The present invention also pertains to a method for printing polyester and polyester blends fabrics with the dye-based inkjet ink set, and a polyester and polyester blends fabrics so printed.

This invention pertains to an aqueous disperse dye black ink and inkjet ink set containing this disperse dye black ink. The ink and ink sets are especially suitable for printing of textiles, especially polyester and polyester blends.

Disperse dye black ink

The present invention pertains to a dye-based inkjet ink set and, more particularly, to a dye-based inkjet ink set suitable for printing on polyamide fabric. The present invention also pertains to a method for printing a polyamide fabric with the dye-based inkjet ink set, and a polyamide fabric so printed.

A process for dyeing certain textile fibers, utilizing vat acid dyeing and specific additional (second) reducing agents such as &#x3b1;-hydroxyalkylsulfinic acids, their salts and 1,2,4-trithiolane, resulting in excellent depth of shade and washfastness, is provided.
