THERMAL TRANSFER FILM

摘要

The present invention relates to a thermal transfer film. Particularly, the present invention relates to a thermal transfer film formed by adding a binder and a dye to a photothermal conversion layer so as to decrease the deviation in OD values at a specific wavelength absorbed by the dye. Accordingly, the thermal transfer film has a uniform OD value and an improved appearance, to thereby more efficiently transfer a transfer material from a transfer layer to a receptor. More particularly, the present invention relates to a thermal transfer film formed by further adding a pigment to the photothermal conversion layer so as to further decrease the deviation in OD values at the specific wavelength absorbed by the dye. Accordingly, the thermal transfer film has a more uniform OD value and a more improved appearance, to thereby more efficiently transfer the transfer material from the transfer layer to the receptor.
