ABSTRACT:
A process for manufacturing a dye-receiving element for thermal dye transfer comprising coating a cushion intermediate layer, a subbing layer, and a dye image-receiving layer on a support, wherein the cushion layer and subbing layer are simultaneously coated, and wherein the subbing layer includes a hydroxylated siloxane polymer surfactant having random recurring units of the following structures I or II: ##STR1## wherein A is --CH.sub.3 or B, and B is a C.sub.1 to C.sub.10 straight chain or branched primary or secondary hydroxy terminated alkylene group, and x, y, and z are such as to provide a molecular weight of from about 1,000 to about 20,000 and from 1 to about 20 hydroxyl groups per polymer molecule. The invention further comprises a receiving element comprising a support having thereon a cushion intermediate layer, a dye image-receiving layer, and a subbing layer between the cushion layer and the dye image-receiving layer, wherein the subbing layer contains a surfactant of the above structures I or II.
