Abstract: A dye acceptor material for thermosublimation printing comprising a support and a dye acceptor layer, characterized in that the dye acceptor layer contains a copolymer ofa) 15 to 75% by weight of an aromatic vinyl compound,b) 5 to 40% by weight (meth)acrylonitrile,c) 10 to 70% by weight (meth)acrylates containing 4 to 18 C atoms in the alcohol radical,d) 0 to 30% by weight other vinyl monomers,with the proviso that the glass transition temperature of the copolymer is above 40.degree. C. and the ratio by weight of component a) to component b) is 1:1 to 4:1, is distinguished by high color density and adequate image stability for minimal lateral diffusion.

Abstract: A dye acceptor element for thermosublimation printing comprising a support and a dye acceptor layer containing a graft polymer of an unsaturated copolyester as the graft base and a vinyl copolymer as the graft shell is distinguished by high color density, high sharpness, good image stability and a minimal tendency towards adhesion to than dye-donor lint.

Abstract: A dye acceptor element for the thermal sublimation printing process, having a base and a dye acceptor layer which contains a polyester formed from diols and dicarboxylic acids, the diol component of the polyester consisting to the extent of 0.5 to 60 mol % of a dimer diol, is distinguished by a high color density and a low tendency to sticking.
