PURPOSE:To lengthen the life of a conducting head by constituting the titled sheet by a conduction resistance layer, which consists of carbon black, a phenoxy resin and a crosslinking agent and has specific surface resistance value, a polyethylene terephthalate film and an ink layer. CONSTITUTION:A sheet 1 for conduction heat transfer recording is formed by a conduction resistance layer 2, which contains carbon black of DPB oil absorption of 300ml/100g or more in Ck=5-35wt%, a phenoxy resin shown by formula (n represents the degree of polymerization) in Cp=20-60wt% and a crosslinking agent such as polyisocyanate in Cc=5-25wt% in Ck+Cp+Cc=60-90wt% as the sum of solid components as conductive dispersed particles, a supporter layer 3 composed of a biaxial oriented film made of polyethylene terephthalate in 2- 10mum thickness, and an ink layer 4. An ink layer of yellow, magenta, cyan and black can be applied as the ink layer. |
