<p>A dye donor element for thermal dye transfer has a support carrying in one area, a layer contg. an image dye in a binder and, in another area, a transferable protection layer. The two areas are approx. equal in size and the protection layer contains poly(vinyl formal), poly(vinyl benzal) or pref. poly(vinyl acetal) contg. at least 5 mol.% hydroxyl. Also claimed is (a) a thermal dye transfer assembly comprising the donor element above, superposed with a dye receiving element, and (b) a method of forming a protection layer on a dye image. The method involves imagewise heating to transfer a dye image from a donor to a receiver and thermally transferring a protection layer onto the dye image. The dye donor and protection layers are carried by the same or separate elements.</p> |
