An inkjet ink contains a pigment, a polysaccharide, a water-soluble organic solvent, and self-emulsifying polyolefin resin particles. The polysaccharide has a percentage content of at least 0.01% by mass and no greater than 0.20% by mass. The water-soluble organic solvent contains a specific glycol ether compound. The specific glycol ether compound has a percentage content of at least 3.0% by mass and no greater than 24.0% by mass. A ratio (M.sub.Y/M.sub.X) of a mass M.sub.Y of the pigment to a mass M.sub.X of the self-emulsifying polyolefin resin particles is at least 0.24 and no greater than 3.10.

The present invention relates to an electrically conductive composition comprising a) a resin selected from nitrocellulose, chlorinated polyester, chlorinated polyether, chlorinated polyvinyl, chlorinated polyacetate and mixtures thereof; b) electrically conductive particles comprising graphite and carbon black, wherein ratio of said graphite and said carbon black is from 1:1 to 5:1; and c) a solvent, where in ratio of said electrically conductive particles and said resin is from 0.20:1 to 4:1. The compositions according to the present invention can be used in high-speed printing techniques such as flexography and rotogravure printing.

Provided is an ink composition, in particular an inkjet ink composition for use in inkjet printing such as drop on demand inkjet printing or continuous inkjet printing, which is suitable for producing codes on non-porous substrates.
