▎ 摘　　要

NOVELTY - An ink composition comprises a carbon material chosen from graphene, expanded graphite, graphite, carbon black and carbon nanotubes, a dispersing agent and a solvent. The dispersing agent comprises a polymer (P1) and a polymer (P2) having molecular weight different from molecular weight of polymer (P1). USE - Ink composition (claimed). ADVANTAGE - The ink composition has improved carbon material dispersibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of ink composition.
