ABSTRACT:
A receiver sheet for dye-diffusion thermal transfer printing, comprising a sheet-like dielectric substrate supporting a layer of dye-receptive material on one side, has an antistatic treatment on both sides to improve handling. The antistatic treatment on the side supporting the receiver coat comprises a conductive undercoat located between the substrate and the layer of dye-receptive material. Effective conductive undercoat materials include a cross-linked organic polymer containing a plurality of ether linkages doped with an alkali metal salt to provide conductivity. The antistatic treatment on the other side is preferably incorporated into a heat resistant and/or low friction backcoat, but like that of the receiver side, could also be in the form of a conducting undercoat between the substrate and backcoat.
