DONOR FILM COMPRISING LIGHT DIFFUSING LAYER FOR LASER INDUCED THERMAL IMAGING

摘要

The laser beam thermal transfer donor film comprising a base layer, a photothermal conversion layer, a protective layer, and a transfer layer, and further comprising a light diffusion layer laminated on either or both of an upper surface and a lower surface of the photothermal conversion layer. The donor film is laminated with a light diffusion layer adjacent to a light heat conversion layer, which is one of the components constituting the donor film, so that the laser light applied to the donor film is uniformly irradiated onto the light heat conversion layer by the light diffusion layer. do. Therefore, the light diffusion layer is made to uniformly generate heat in the photothermal conversion layer by the laser light, thereby uniformly transferring the transfer element, for example, an organic light emitting material, and to minimize the defect by controlling the transfer width evenly. There is provided a laser light thermoelectric donor film comprising.
