Abstract
An electrothermal transfer recording medium formed with a support layer, a flameproof electrothermal resistive layer on one side of the support and an ink layer on the opposite side of the support is provided. The flameproof electrothermal resistive layer includes carbon black and a brominated aromatic compound with at least two aromatic rings dispersed therein. As used herein, the term 'brominated aromatic compound' includes brominated aromatic compounds and polymers, derivatives and mixtures thereof. The brominated aromatic compounds having at least two aromatic rings are flameproofing agents, improve dispersability of carbon black, are readily micronizable and function to micronize particles of other flame retardants or flame retardants assistants added to the resistive layer.
