ABSTRACT:
An optical conductive thermal transfer ink medium is disclosed, comprising at least the following layers laminated on a light-transmitting substrate in this order: a light-transmitting conductive layer, a photothermal layer exhibiting photo-conductivity, a conductive layer and a thermal transfer ink layer and which is used, when printing, by applying a voltage between the light-transmitting conductive layer and the conductive layer. It may also comprise a low surface energy protection layer between the conductive layer and the thermal transfer ink layer or a conductive heating layer between the photothermal layer and the conductive layer, in the above described structure.
