More Information
Summary: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.
