A thermal dye image receiver element has, in order, a cellulosic raw base support, an antistatic subbing layer, and a thermal dye receiving layer. The cellulosic raw base support has an internal electrical resistance (WER) that is at least 1 log ohm/square greater than the surface electrical resistance (SER) of the antistatic subbing layer. This arrangement of antistatic properties overcomes a static problem in the thermal dye image receiver elements by properly balancing the conductivity between the two antistatic locations.
