PURPOSE:To provide excellent economy and a high speed printing by providing an ink layer on a film made of aromatic polyamide resin, soluble resin, and conductive filler. CONSTITUTION:An ink layer is provided on a film made of aromatic polyamide resin, soluble resin and conductive filler. The polyamide resin desirably contains polymer containing 50mol% or more desirably 70mol% of repetition structure unit of predetermined composition. The soluble resin is not particularly limited if it dissolved 1wt.% or more of solvent for dissolving the polyamide resin, and desirably amide solvent such as N-methylpryrrolidone or resin dissolved 1wt.% or more in dimethylacetamide. The soluble resin is desirably, for example, polycarbonate, polyethersulfon, polyarylate. The filler is not particularly limited if it has electric conductivity, but carbon black is desirable in view of mutual solubility, dispersibility with the resin and further economy. |
