▎ 摘　　要

NOVELTY - Inkjet ink comprises graphene, resin and solvent, where the resin has polycyclic aromatic group. USE - The inkjet ink used for forming image and monochrome printing. ADVANTAGE - The inkjet ink forms image with excellent ejection properties and image density, has improved dispersibility, and adopts graphene with high opacity due to its unique electrical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing inkjet ink, involving melt-kneading graphene powder and resin, dispersing obtained kneaded material in solvent, and preparing inkjet ink using obtained dispersion liquid.
