PURPOSE:To eliminate the need for a back coat layer by providing a thermal transfer layer on a laminate of an aromatic polyamide layer having a surface roughness of not more than 0.1mum and a glossiness of at least 400 and an aro matic polyamide layer having a surface roughness of 0.12-1.0mum, on said layer. CONSTITUTION:A raw liquid of an aromatic polyamide A comprising less than 5wt.% of inorganic or organic particles of ZnO, Al2O3, carbon black or the like with a particle diameter of 20mmum-5mum and a raw liquid of an aromatic polyamide B comprising 0.1-80wt.% of inorganic or organic particles (similar to the above) with a particle diameter of 20mmum-10mum are laminated through a mixing pipe to obtain a laminate which comprises an aromatic polyamide layer A having a surface roughness of not more than 0.1mum and a glossiness of at least 400 and an aromatic polyamide layer B having a surface roughness of 0.12-1.0mum, and has a Young's modulus at 200 deg.C of at least 100kg/mm<2>. A thermal transfer layer is provided on the layer A of the laminate to produce a transfer material for thermal recording. |
