NOVELTY - An ink composition comprises 20-50 wt.% conductive powder, 10-30 wt.% organic binder, 5-30 wt.% curing agent, 20-50 wt.% solvent, and 1-10 wt.% dispersant. The conductive powder comprises carbon black and graphite. The organic binder comprises acrylic polyol. The solvent comprises ethyl carbitol acetate and propylene glycol methyl ether. A thin film formed by applying the ink composition has sheet resistance of less than 1000 Omega /square. USE - Ink composition used for forming printed material (claimed). ADVANTAGE - The ink composition has desired electromagnetic properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of a printed material with electromagnetic properties, which involves preparing the base material, printing a pattern on the base material using the ink composition and curing the material on which the pattern is printed.
