Abstract (en)

[origin: WO9403334A1] A film is provided for producing a dye diffusion thermal transfer image comprising diffusible dyes physically located in the pores of a porous film having a pore size between 20 and 400 Gurlex without any binder. The diffusion of dyes can be carried out at low energy and, thus, the service life of the thermal head can be extended. The film further posses high thermal sensitivity and high gradation.
