Abstract
A donor film and a thermal imaging method, the film including a base layer; a first light-to-heat conversion layer on the base layer; and a second light-to-heat conversion layer on the first light-to-heat conversion layer and to which an organic material is deposited, wherein the first light-to-heat conversion layer and the second light-to-heat conversion layer respectively absorb light of different wavelengths.
Claims7
A donor film for use in effecting thermal imaging on an imaging substrate, the donor film comprising:
- a base layer;
- a first light-to-heat conversion layer on the base layer;
- and
- a second light-to-heat conversion layer on the first light-to-heat conversion layer, the second light-to-heat conversion layer including an organic material for depositing on the imaging substrate,
- wherein the first light-to-heat conversion layer transmits light having a wavelength that is absorbed by the second light-to-heat conversion layer.

A thermal imaging method, the method comprising:
- providing a donor film such that the donor film includes:
- a base layer;
- a first light-to-heat conversion layer on the base layer;
- and
- a second light-to-heat conversion layer on the first light-to-heat conversion layer and to which an organic material is deposited, wherein the first light-to-heat conversion layer and the second light-to-heat conversion layer respectively absorb light of different wavelengths;
- heating the second light-to-heat conversion layer by irradiating light of a wavelength that transmits through the first light-to-heat conversion layer and that is absorbed by the second light-to-heat conversion layer;
- heating the first light-to-heat conversion layer by irradiating light of a wavelength that is absorbed by the first light-to-heat conversion layer;
- and
- thermally imaging an organic material of the second light-to-heat conversion layer to an imaging substrate by thermal expansion when the first light-to-heat conversion layer is heated.
