Abstract

To transfer a toner image from a toner-treated surface, a toner transfer film is employed, which comprises a transparent base carrying a transparent layer which is capable of picking up toner and has a temporary slight surface tack, the layer consisting of a mixture containing a polymeric and/or pre-polymeric binder, a polymerizable low molecular weight compound and a polymerization initiator. After transfer, the toner image can be permanently fixed to the toner transfer film by heating the film and/or exposing it to light.
