Ink comprising dispersed nanopigment micelles and printed textiles obtained therefrom

A water-based ink comprising nanopigment micelles (1), said nanopigment micelles (1) comprising a water-insoluble pigment particle (1a) and a polymeric dispersing agent (1b) around said pigment particle (1a), whereby said pigment particles (1a) have an average particle size between 150 nm and lower than 200 nm, as determined by ISO 13320:2009;

• wherein said polymeric dispersing agent (1b) is a block copolymer of a copolyamide having at least one hydrophilic segment and at least one hydrophobic segment;
• a binder polymer (2);
• and
• wherein said copolyamide has a softening point between 105° C. and 125° C.
