Ink comprising dispersed nanopigment micelles and printed textiles obtained therefrom

A water-based ink comprising:

• nanopigment micelles (1), said nanopigment micelles (1) comprising a pigment particle (1a) and a polymeric dispersing agent (1b), wherein said pigment particles (1a) have an average particle size between 150 nm and lower than 200 nm, as determined by ISO 13320:2009;
• a binder polymer (2);
• wherein said polymeric dispersing agent (1b) is a block copolymer comprising at least one hydrophilic segment comprising a homo- or co-polyether block amide and at least one hydrophobic segment comprising a homo- or co-polyether block amide, and
• wherein said nanopigment micelles are comprised in an amount of 40 wt. % to 60 wt. %, of said pigment particles (1a) and of 60 wt. % to 40 wt. % of said polymeric dispersing agent (1b).
