Patent ID: 7141348

Claim:
A method to form a device disposing on a receptor substrate, the device being formed by transferring a multicomponent transfer unit from a thermal transfer element to the receptor substrate, wherein the multicomponent transfer unit comprises the device, and the thermal transfer element comprises a donor substrate and a transfer layer with a releasable adhesion layer disposed between the donor substrate and the transfer layer, the transfer layer comprising a plurality of multicomponent transfer units, and the releasable adhesion layer comprising a polymer composition having a low delamination temperature in the presence of light, whereby allowing the delamination of the adhesion layer to transfer the selected multicomponent units by exposing the selected multicomponent units to light; and maintaining good adhesion between the donor substrate and the transfer layer at a temperature higher than the delamination temperature in the absence of light, whereby permitting processing the multicomponent transfer units at a temperature higher than the delamination temperature, the method comprising imagewise exposing the releasable adhesion layer to light; and heating to decompose the releasable adhesion layer to transfer only the imagewise light-exposed areas to the receptor.
