Disclosed are thermal transfer elements and processes for patterning solvent-coated layers and solvent-susceptible layers onto the same receptor substrate. These donor elements and methods are particularly suited for making organic electroluminescent devices and displays. The donor elements can include a substrate, an optional light-to-heat conversion layer, and a single or multicomponent transfer layer that can be imagewise transferred to a receptor to form an organic electroluminescent device, portions thereof, or components therefor. The methods offer advantages over conventional patterning techniques such as photolithography, and make it possible to fabricate new organic electroluminescent device constructions.

1. A method of transferring a multicomponent transfer unit to a receptor, the method comprising:providing a receptor comprising a substrate and a receptor layer disposed on the substrate, wherein the receptor layer is formed of a first material; providing a thermal transfer element comprising a substrate and a multicomponent transfer unit, the multicomponent transfer unit comprising a first layer formed of the first material; contacting the receptor layer of the receptor and the first layer of the thermal transfer element; and selectively heating the thermal transfer element to transfer the multicomponent transfer unit to the receptor according to a pattern to form at least a portion of both a first operational layer and a second operational layer of a multilayer device, wherein the first operational layer is configured and arranged to conduct or produce a charge carrier.
