Abstract
A process for producing a donor sheet for a thin-film formation comprising: while transporting a sheet on which a light-to-heat conversion layer has already been formed, forming a transfer layer on the light-to-heat conversion layer and drying the transfer layer.
Claims5
A process for producing a donor sheet for a thin-film formation comprising:
- while transporting a sheet on which a light-to-heat conversion layer has already been formed, forming a transfer layer on the light-to-heat conversion layer and drying the transfer layer, the sheet being transported by rotating a transporting roller in contact with the sheet, the sheet being transported by engaging holes in both edge portions of the sheet with projections arranged intervals on the transporting roller.
A process for producing a donor sheet for a thin-film formation comprising:
- while transporting a sheet on which a light-to-heat conversion layer has already been formed, forming a transfer layer on the light-to-heat conversion layer and drying the transfer layer, the sheet being transported by rotating a transporting roller in contact with the sheet, the sheet being transported as it is stuck by suction to the transporting roller.
A process for producing a donor sheet for a thin-film formation comprising:
- while transporting a sheet on which a light-to-heat conversion layer has already been formed, forming a transfer layer on the light-to-heat conversion layer and drying the transfer layer the sheet being transported by rotating a transporting roller in contact with the sheet, and drying the transfer layer by a heater incorporated in the transporting roller.
A process for producing a donor sheet for a thin-film formation comprising:
- while transporting a sheet on which a light-to-heat conversion layer has already been formed, forming a transfer layer on the light-to-heat conversion layer and drying the transfer layer:
- and
- drying the transfer layer under an inert gas atmosphere.
