This application relates to ink compositions, in particular ink compositions for use in continuous inkjet printing. The ink compositions are suitable for producing printed images for example with reduced printer error and good adhesion to low surface energy substrates, in particular, low energy substrates such as polypropylene, LDPE and HDPE. The ink composition contains a liquid carrier and carbon black. The ink composition has a surface resistance of at least 2 MΩ/sq after washing the printed deposit with the liquid carrier and an adhesion of 50% or more after applying an adhesive tape to the printed deposit and removing the adhesive tape.

Ink composition for inkjet printing

This application relates to an ink composition, in particular an ink composition for use in continuous inkjet printing. The ink composition for use in continuous inkjet printing, contains a siloxane surfactant and a metal conductivity salt. The ink composition is suitable for producing printed images with good adhesion to low surface energy substrates, in particular, low energy substrates such as polypropylene, LDPE and HDPE. The ink composition has a liquid carrier, a colourant, a siloxane surfactant and a metal conductivity salt. The siloxane surfactant is present in an amount greater than 0.1% by weight of the ink composition.
